發布時間：2024/9/27 编程问答 23 豆豆

生活随笔收集整理的這篇文章主要介紹了 dexpress 流程图_DevExpress常用操作小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

1、如何解決單擊記錄整行選中的問題

View->OptionsBehavior->EditorShowMode 設置為：Click

2、如何新增一條記錄

(1)、gridView.AddNewRow()

(2)、實現 gridView_InitNewRow 事件

3、如何解決 GridControl 記錄能獲取而沒有顯示出來的問題

gridView.populateColumns();

4、如何讓行只能選擇而不能編輯(或編輯某一單元格)

(1)、View->OptionsBehavior->EditorShowMode 設置為：Click

(2)、View->OptionsBehavior->Editable 設置為：false

5、如何禁用 GridControl 中單擊列彈出右鍵菜單

設置 Run Design->OptionsMenu->EnableColumnMenu 設置為：false

6、如何隱藏 GridControl 的 GroupPanel 表頭

設置 Run Design->OptionsView->ShowGroupPanel 設置為：false

7、如何禁用 GridControl 中列頭的過濾器過濾器如下圖所示：

設置 Run Design->OptionsCustomization->AllowFilter 設置為：false

8、如何在查詢得到 0 條記錄時顯示自定義的字符提示/顯示如圖所示：

方法如下：

//When no Records Are Being Displayed

private void gridView1_CustomDrawEmptyForeground(object sender, CustomDrawEventArgs e)

{

//方法一(此方法為GridView設置了數據源綁定時，可用)

ColumnView columnView = sender as ColumnView;

BindingSource bindingSource = this.gridView1.DataSource as BindingSource;

if(bindingSource.Count == 0)

{

string str = "沒有查詢到你所想要的數據!";

Font f = new Font("宋體", 10, FontStyle.Bold);

Rectangle r = new Rectangle(e.Bounds.Top + 5, e.Bounds.Left + 5, e.Bounds.Right - 5, e.Bounds.Height - 5);

e.Graphics.DrawString(str, f, Brushes.Black, r); }

//方法二(此方法為GridView沒有設置數據源綁定時，使用，一般使用此種方法)

if (this._flag)

{ if (this.gridView1.RowCount == 0)

{ string str = "沒有查詢到你所想要的數據!"; Font f = new Font("宋體", 10, FontStyle.Bold);

Rectangle r = new Rectangle(e.Bounds.Left + 5, e.Bounds.Top + 5, e.Bounds.Width - 5, e.Bounds.Height - 5);

e.Graphics.DrawString(str, f, Brushes.Black, r); } } }

9、如何顯示水平滾動條？或

設置 this.gridView.OptionsView.ColumnAutoWidth = false;

.....列表寬度自適應內容

gridview1.BestFitColumns();

10、如何定位到第一條數據/記錄？

設置 this.gridView.MoveFirst()

11、如何定位到下一條數據/記錄？

設置 this.gridView.MoveNext()

12、如何定位到最后一條數據/記錄？

設置 this.gridView.MoveLast()

13、設置成一次選擇一行，并且不能被編輯

this.gridView1.FocusRectStyle = DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.RowFocus;

this.gridView1.OptionsBehavior.Editable = false;

this.gridView1.OptionsSelection.EnableAppearanceFocusedCell = false;

14、如何顯示行號？

private void gvPayList_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)

{

e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;

if (e.Info.IsRowIndicator)

{

if (e.RowHandle >= 0)

{

e.Info.DisplayText = (e.RowHandle + 1).ToString();

}

else if (e.RowHandle < 0 && e.RowHandle > -1000)

{

e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;

e.Info.DisplayText = "G" + e.RowHandle.ToString();

}

15、如何讓各列頭禁止移動？

設置 gridView1.OptionsCustomization.AllowColumnMoving = false;

16、如何讓各列頭禁止排序？

設置 gridView1.OptionsCustomization.AllowSort = false;

17、如何禁止各列頭改變列寬？

設置 gridView1.OptionsCustomization.AllowColumnResizing = false;

18.拖動滾動條時固定某一列

設置Columns，選擇要固定的列。設置Fixed屬性，可以選擇：固定在左邊、固定在右邊、不固定。

19.獲取選定行,指定列單元格的內容

return gridView1.GetRowCellValue(pRows[0], ColumName).ToString ();

20.分組顯示

OptionsView>OptionsBehavior>AutoExpandAllGroups = True

選擇要分組的列，將GroupIndex屬性設置為0

21.格式化數據

private void gvList_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e)

{

if (this.gvList.FocusedColumn.FieldName == "passQty")

{

string passQty = e.Value.ToString().Trim();

int receiveQty = orderDetailList[this.gvList.FocusedRowHandle].qty;

if (!JXType.IsIntBigThanZero(passQty))

{

e.Valid = false;

e.ErrorText = "合格數量必須為大于等于0小于等于接貨數量的整數！";

}

else

{

if (int.Parse(passQty) > receiveQty)

{

e.Valid = false;

e.ErrorText = "合格數量必須為大于0小于等于接貨數量的整數！";

}

22.合并表頭

///初始化表格

using DevExpress.XtraGrid.Columns;

using DevExpress.XtraGrid.Views.Base;

using DevExpress.XtraGrid.Views.BandedGrid;

using DevExpress.XtraEditors.Repository;

private void InitGrid()

{

// advBandedGridView1是表格上的默認視圖，注意這里聲明的是：BandedGridView

BandedGridView view = advBandedGridView1 as BandedGridView;

view.BeginUpdate(); //開始視圖的編輯，防止觸發其他事件

view.BeginDataUpdate(); //開始數據的編輯

view.Bands.Clear();

view.OptionsView.ShowColumnHeaders = false;? ? ? ? ? ? ? ? ? ? ? ? //因為有Band列了，所以把ColumnHeader隱藏

//添加列標題

GridBand bandID = view.Bands.AddBand("ID");

bandID.Visible = false; //隱藏ID列

GridBand bandName = view.Bands.AddBand("姓名");

GridBand bandSex = view.Bands.AddBand("性別");

GridBand bandBirth = view.Bands.AddBand("出生日期");

GridBand bandScore = view.Bands.AddBand("分數");

GridBand bandMath = bandScore.Children.AddBand("數學");

GridBand bandChinese = bandScore.Children.AddBand("語文");

GridBand bandEnglish = bandScore.Children.AddBand("英語");

GridBand bandSubTotal = bandScore.Children.AddBand("小計");

GridBand bandRemark = view.Bands.AddBand("備注");

bandFile.AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;//這是合并表頭居中顯示

view.EndDataUpdate();//結束數據的編輯

view.EndUpdate();? //結束視圖的編輯

}

具體可看

dev gridcontrol 合并表頭

23.? //動態添加列

DevExpress.XtraGrid.Columns.GridColumn Col1 = new DevExpress.XtraGrid.Columns.GridColumn();

Col1.FieldName = "name";

Col1.Caption = "名字";

Col1.Visible = false;

Col1.VisibleIndex = gvCountry.Columns.Count;

gvCountry.Columns.Add(Col1);

24。設置自動增加的行號

private void gridview_CustomDrawRowIndicator(object sender,? ? ? ? ? ? ? ? ? ? ? ? ? ? DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)

{

e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;

if (e.Info.IsRowIndicator)

{

if (e.RowHandle >= 0)

{

e.Info.DisplayText = (e.RowHandle + 1).ToString();

}

else if (e.RowHandle < 0 && e.RowHandle > -1000)

{

e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;

e.Info.DisplayText = "G" + e.RowHandle.ToString();

}

｝

25.特效：gridcontrol中有5種view 型式，普通的是gridview，然后分別為cardview、BandedView、Advanced BandedView、LayoutView；共5種。

1)、view組中把OptionView下的viewmode 設置成“Carousel”就達到這種“旋轉木馬”式的gridcontrol view 特效了

2)、layoutView1.OptionsCarouselMode.PitchAngle 這個屬性決定“旋轉木馬”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 傾角; 節錐半角

3)、Roll Angle 屬性決定著傾側角度

4)、指定數據源，顯示數據：

//顯示數據

private void showData(List list)

{

DataTable dt = new DataTable("OneEmployee");

dt.Columns.Add("Caption", System.Type.GetType("System.String"));

dt.Columns.Add("Department", System.Type.GetType("System.String"));

dt.Columns.Add("PhotoName", System.Type.GetType("System.Byte[]"));

for (int i = 0; i < list.Count; i++)

{

DataRow dr = dt.NewRow();

dr["Caption"] = list[i].Name;

dr["Department"] = list[i].Department;

string imagePath = @"D:\C#\photos\" + list[i].PhotoPath;

dr["PhotoName"] = getImageByte(imagePath);

dt.Rows.Add(dr);

}

gridControl1.DataSource = dt;

}

//返回圖片的字節流byte[]

private byte[] getImageByte(string imagePath)

{

FileStream files = new FileStream(imagePath, FileMode.Open);

byte[] imgByte = new byte [files.Length ];

files.Read(imgByte, 0, imgByte.Length);

files.Close();

return imgByte;

}

26.檢查數據的有效性

在gridview的ValidateRow事件中加入檢查代碼：

#region 檢查數據

private void gridView1_ValidateRow(object sender, ValidateRowEventArgs e)

{

GridView view = sender as GridView;

view.ClearColumnErrors();

if (view.GetRowCellValue(e.RowHandle, "ReceiveDate") == DBNull.Value)

{

e.Valid = false;

view.SetColumnError(view.Columns["ReceiveDate"], "必須指定日期");

}

27.設某一列文字和標題局中顯示

gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

28.列表過濾條件多選

列名.OptionsFilter.FilterPopupMode= DevExpress.XtraGrid.Columns.FilterPopupMode.CheckedList

29.隔行換色的方法

this.gridView1.Appearance.OddRow.BackColor = Color.White;? // 設置奇數行顏色 // 默認也是白色可以省略

this.gridView1.OptionsView.EnableAppearanceOddRow = true;? // 使能 // 和和上面綁定同時使用有效

this.gridView1.Appearance.EvenRow.BackColor = Color.WhiteSmoke; // 設置偶數行顏色

this.gridView1.OptionsView.EnableAppearanceEvenRow = true;? // 使能 // 和和上面綁定同時使用有效

1.隱藏最上面的GroupPanel

gridView1.OptionsView.ShowGroupPanel=false;

2.得到當前選定記錄某字段的值

sValue=Table.Rows[gridView1.FocusedRowHandle][FieldName].ToString();

3.數據只讀

gridView1.OptionsBehavior.Editable=false;

4.不顯示MasterDetailView

gridView1.OptionsDetail.EnableMasterViewMode=false;

5.修改最上面的GroupPanel內容

gridView1.GroupPanelText="柳生飄絮";

6.設置數據源:

gridControl1.DataSource = dt;

綁定每一列的FiledName--屬性

對于Oracle數據庫,所有的在設計器里寫的程序中的字段名必須大寫,否則可能綁定不上字段,sqlserver沒有這個限制.

7.讀寫拷貝權限設置

只讀不可拷貝：

ColumnViewOptionsBehavior.Editable = False

只讀可拷貝:

ColumnViewOptionsBehavior.Editable = True

OptionsColumn.AllowEdit = True

OptionsColumn.ReadOnly = True

可編輯:

ColumnViewOptionsBehavior.Editable = True

OptionsColumn.AllowEdit = True

OptionsColumn.ReadOnly = False

8.模板列的設置:

到Columns中，在他的屬性中找到ColumnEdit.

以LookUpEdit為例：

首先從Designer左邊菜單In-Place Editor Repository中添加LookUpEdit.取名為Re1.然后.在他的Columns屬性中添加3列.Caption依次為:編號,姓名,性別.FieldName依次為:FID,FNAME,FSEX.然后將Re1的NullText設置成空.

AutoSearchColumnIndex屬性設置為2.ImmediatePopup屬性設置為True.

SearchMode設置為OnlyInPopup.

然后將這個模板列附加到我們上面提到的列1(也就是將列1的ColumnEdit屬性設成Re1)

最后我們還要在代碼里面給Re1綁定數據源和顯示項.

Re1.DataSource = DALUse.Query("select fid,fname,fsex from dual").Tables[0];

Re1.DisplayMember = "FSEX";

Re1.ValueMember = "FNAME";

9.設某一列文字和標題局中顯示

gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

10.去掉某一列上面的自動篩選功能(Filter)

gridView1.Columns[0].OptionsFilter.AllowAutoFilter = false;

gridView1.Columns[0].OptionsFilter.AllowFilter = false;

gridView1.Columns[0].OptionsFilter.ImmediateUpdateAutoFilter = false;

11.設置凍結列(左凍結)

gridView1.Columns[0].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;

12.得到單元格數據(0行0列)

string ss=gridView1.GetRowCellDisplayText(0, gridView1.Columns[0]);

string ss = gridView1.GetRowCellValue(0, gridView1.Columns[0]);

13.設置單元格數據(將0行0列的單元格賦值123)

gridView1.SetRowCellValue(0, gridView1.Columns[0], "123");

13.手動添加dev的列

DevExpress.XtraGrid.Columns.GridColumn Col1=new DevExpress.XtraGrid.Columns.GridColumn ();

Col1.FieldName="FID";

Col1.Visible=true;

Col1.VisibleIndex=gridView1.Columns.Count;

gridView1.Columns.Add(Col1);

14.設置自動增加的行號,需要先添加給gridview添加事件CustomDrawRowIndicator

private void gridview_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)

{

if (e.Info.IsRowIndicator && e.RowHandle >= 0)

e.Info.DisplayText = (e.RowHandle + 1).ToString();

}

15.刪除: (修改了dgvdel里的datagridviewdel方法)

public static void datagridviewdel_Dev(DevExpress.XtraGrid.Views.Grid.GridView Mydgv)

{

if (MessageBox.Show("你確定要刪除選中的記錄嗎？", "刪除提示", MessageBoxButtons.YesNo, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2, 0, false) == DialogResult.Yes)

{

int iSelectRowCount = Mydgv.SelectedRowsCount;

if (iSelectRowCount > 0)

{

Mydgv.DeleteSelectedRows();

}

16. 新增: (對于新增,其本身的AddNewRow方法就可以做到)

private void btn_add_Click(object sender, EventArgs e)

{

gridView1.AddNewRow();

}

具體如果對于新加行還有什么特別的設置,可以在它gridView1_InitNewRow事件中填寫:

private void gridView1_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)

{

ColumnView View = sender as ColumnView;

View.SetRowCellValue(e.RowHandle, View.Columns[0], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns[0])); //復制最后一行的數據到新行

View.SetRowCellValue(e.RowHandle, View.Columns[1], gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2), gridView1.Columns[1])); //復制最后一行的數據到新行

}

17. 保存 (第三方控件提供的RefreshData和RefreshDataSource方法對于保存數據都不好使,最后還是使用了Dgvsave的datagridviewsave方法,用這個方法就可以)

18.特效：gridcontrol中有5種view 型式，普通的是gridview，然后分別為cardview、BandedView、Advanced BandedView、LayoutView；共5種。

1)、view組中把OptionView下的viewmode 設置成“Carousel”就達到這種“旋轉木馬”式的gridcontrol view 特效了

2)、layoutView1.OptionsCarouselMode.PitchAngle 這個屬性決定“旋轉木馬”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 傾角; 節錐半角

3)、Roll Angle 屬性決定著傾側角度

4)、指定數據源，顯示數據：

//顯示數據

private void showData(List list)

{

DataTable dt = new DataTable("OneEmployee");

dt.Columns.Add("Caption", System.Type.GetType("System.String"));

dt.Columns.Add("Department", System.Type.GetType("System.String"));

dt.Columns.Add("PhotoName", System.Type.GetType("System.Byte[]"));

for (int i = 0; i < list.Count; i++)

{

DataRow dr = dt.NewRow();

dr["Caption"] = list[i].Name;

dr["Department"] = list[i].Department;

string imagePath = @"D:\C#\photos\" + list[i].PhotoPath;

dr["PhotoName"] = getImageByte(imagePath);

dt.Rows.Add(dr);

}

gridControl1.DataSource = dt;

}

//返回圖片的字節流byte[]

private byte[] getImageByte(string imagePath)

{

FileStream files = new FileStream(imagePath, FileMode.Open);

byte[] imgByte = new byte [files.Length ];

files.Read(imgByte, 0, imgByte.Length);

files.Close();

return imgByte;

}

19.檢查數據的有效性

在gridview的ValidateRow事件中加入檢查代碼：

#region 檢查數據

private void gridView1_ValidateRow(object sender, ValidateRowEventArgs e)

{

GridView view = sender as GridView;

view.ClearColumnErrors();

if (view.GetRowCellValue(e.RowHandle, "ReceiveDate") == DBNull.Value)

{

e.Valid = false;

view.SetColumnError(view.Columns["ReceiveDate"], "必須指定日期");

}

#endregion

調用gridview.UpdateCurrentRow()方法執行檢查

最常用的DevExpress Winform 4個代碼片段：

一、GridControl的刪除操作

private void rILinkEditInfoDel_Click(object sender, EventArgs e)

{

if (XtraMessageBox.Show("請確定是否刪除當前記錄？", "警告", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)

{

DataRow row = gvInfos.GetDataRow(gvInfos.FocusedRowHandle);

delByCode(row["Code"].ToString());

XtraMessageBox.Show("操作成功！");

}

二、綁定非數據表中列

Hashtable ht = new Hashtable();

private void gridView6_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)

{

GridView View = sender as GridView;

if (e.RowHandle >= 0)

{

object needAlert = View.GetRowCellValue(e.RowHandle, View.Columns["needAlert"]);

if (needAlert != null & needAlert != DBNull.Value && needAlert.ToString().Trim() != "0" & View.GetRowCellValue(e.RowHandle, View.Columns["Value"]) != DBNull.Value)

{

decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns["Value"]));

object MinValue = View.GetRowCellValue(e.RowHandle, View.Columns["MinValue"]);

object MaxVlaue = View.GetRowCellValue(e.RowHandle, View.Columns["MaxValue"]);

if (MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() != "" & MaxVlaue != DBNull.Value && MaxVlaue != null & MaxVlaue.ToString() != "")

{

decimal gridColumn2 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns["MinValue"]));

decimal gridColumn1 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns["MaxValue"]));

if (gridColumn2 > AverValue || AverValue > gridColumn1)

{

if (!ht.ContainsKey("pic"))

ht.Add("pic", GetImage(1));

e.Value = ht["pic"];

}

///

/// 由資源文件獲取圖片

///

byte[] GetImage(int key)

{

Image img = DevExpress.Utils.Controls.ImageHelper.CreateImageFromResources(string.Format("RiverSys.Resources.{0}.gif", key.ToString()), typeof(RiverInfos).Assembly);

return DevExpress.XtraEditors.Controls.ByteImageConverter.ToByteArray(img, ImageFormat.Gif);

}

///

/// 動態根據條件設置行樣式

///

private void gridView6_RowStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e)

{

GridView View = sender as GridView;

if (e.RowHandle >= 0)

{

object needAlert = View.GetRowCellValue(e.RowHandle, View.Columns["needAlert"]);

if (needAlert != null & needAlert != DBNull.Value && needAlert.ToString().Trim() != "0" & View.GetRowCellValue(e.RowHandle, View.Columns["Value"]) != DBNull.Value)

{

decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns["Value"]));

object MinValue = View.GetRowCellValue(e.RowHandle, View.Columns["MinValue"]);

object MaxVlaue = View.GetRowCellValue(e.RowHandle, View.Columns["MaxValue"]);

if (MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() != "" & MaxVlaue != DBNull.Value && MaxVlaue != null & MaxVlaue.ToString() != "")

{

decimal gridColumn2 = Convert.ToDecimal(MinValue);

decimal gridColumn1 = Convert.ToDecimal(MaxVlaue);

if (gridColumn2 > AverValue || AverValue > gridColumn1)

{

e.Appearance.ForeColor = Color.Red;

e.Appearance.BackColor = Color.LightGray;

}

三、GridControl 中顏色選擇控件

private void gvMapColor_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)

{

GridView view = sender as GridView;

DataView dv = view.DataSource as DataView;

if (e.IsGetData)

{

string strVal = dv[e.ListSourceRowIndex]["Color"].ToString();

if (strVal != "")

{

//e.Value = DevExpress.Utils.StyleLayout.ColorFromString(strVal);

e.Value = Common.HexToColor(strVal);

}

else

{

//Color colorVal = DevExpress.Utils.StyleLayout.ColorFromString(e.Value.ToString());

Color colorVal = (Color)e.Value;

dv[e.ListSourceRowIndex]["Color"] = Common.RGB_HEX(colorVal.ToArgb());

}

四、關于 GridControl 驗證示例

/**

/// 初始化GridView，綁定數據

///

private void GridViewBindData(string parentId)

{

this.gridView1.Columns.Clear();

this.FDs= areaSetupActionHelper.getDsRegionByParentId(parentId);

this.gridCArea.DataSource =this.FDs.Tables[0].DefaultView;

this.gridView1.Columns["id"].VisibleIndex = -1;

this.gridView1.Columns["childCounts"].VisibleIndex = -1;

this.gridView1.Columns["reg_id"].Caption = "區劃編號";

this.gridView1.Columns["reg_name"].Caption = "區劃名稱";

this.gridView1.Columns["parent_id"].Caption = "父區劃編號";

this.gridView1.Columns["reg_desc"].Caption = "區劃描述";

this.gridView1.Columns["parent_id"].ImageIndex =1;

this.gridView1.Columns["reg_desc"].ImageIndex = 0;

RepositoryItemTextEdit textEditReg_Id = new RepositoryItemTextEdit();

textEditReg_Id.Mask.EditMask =parentId+"\\d{2,3}";

textEditReg_Id.Mask.MaskType = DevExpress.XtraEditors.Mask.MaskType.Regular;

this.gridView1.Columns["reg_id"].ColumnEdit = textEditReg_Id;

this.gridView1.Columns["reg_desc"].ColumnEdit = new RepositoryItemMemoExEdit();

TreeListNode node = this.treelArea.FocusedNode.ParentNode;

string fid = node==null?"0":node.GetValue("RegID").ToString().Trim();

DataSet ds = areaSetupActionHelper.getDsRegionByParentId(fid);

RepositoryItemLookUpEdit lookUEParent_Id = new RepositoryItemLookUpEdit();

lookUEParent_Id.Columns.Add(new LookUpColumnInfo("reg_id", 40, "區劃編號"));

lookUEParent_Id.Columns.Add(new LookUpColumnInfo("reg_name", 40, "區劃名稱"));

lookUEParent_Id.DataSource = ds.Tables[0].DefaultView;

lookUEParent_Id.ValueMember = "reg_id";

lookUEParent_Id.DisplayMember = "reg_id";

this.gridView1.Columns["parent_id"].ColumnEdit = lookUEParent_Id;

}

/**

/// gridView單元格驗證的相關處理程序

///

private void gridView1_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e)

{

if (e.Valid == false&this.gridView1.FocusedColumn.FieldName == "reg_id")

{

e.ErrorText = "區劃編號不合法！\n應為父區劃編號加2～3位數據組成！";

}

if (this.gridView1.FocusedColumn.FieldName == "reg_name")

{

Regex reg=new Regex(@"[\u4e00-\u9fa5]{1,20}");

Match m=reg.Match(e.Value.ToString().Trim());

if (m.Length != e.Value.ToString().Trim().Length)

{

e.Valid = false;

e.ErrorText = "區劃名稱應為漢字\n長度為1至20";

}

private void gridView1_InvalidValueException(object sender, InvalidValueExceptionEventArgs e)

{

if (MyDialog.Alert("　您所填寫的內容不符合規則\n　要放棄您剛才對此項所做的更改嗎？", "您所編輯的內容不符合規則", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)

{

e.ExceptionMode = ExceptionMode.Ignore;

}

/**

/// gridView行驗證的相關處理程序

///

private void gridView1_ValidateRow(object sender, DevExpress.XtraGrid.Views.Base.ValidateRowEventArgs e)

{

string regid = this.gridView1.GetRowCellValue(e.RowHandle, "reg_id").ToString().Trim();

string regName = this.gridView1.GetRowCellValue(e.RowHandle, "reg_name").ToString().Trim();

if ( regid.Length < 1)

{

e.Valid = false;

this.gridView1.SetColumnError(this.gridView1.Columns["reg_id"], "請填寫區劃編號!", DevExpress.XtraEditors.DXErrorProvider.ErrorType.Default);

// e.ErrorText = "區劃名稱不能為空!";

}

if (regName.Length < 1)

{

e.Valid = false;

this.gridView1.SetColumnError(this.gridView1.Columns["reg_name"], "區劃名稱不能為空!", DevExpress.XtraEditors.DXErrorProvider.ErrorType.Default);

}

private void gridView1_InvalidRowException(object sender, DevExpress.XtraGrid.Views.Base.InvalidRowExceptionEventArgs e)

{

if (e.RowHandle >= 0)

{

if (this.gridView1.GetRowCellValue(e.RowHandle, this.gridView1.Columns["reg_id"]).ToString().Trim() == "" || this.gridView1.GetRowCellValue(e.RowHandle, this.gridView1.Columns["reg_name"]).ToString().Trim() == "")

{

if (MyDialog.Alert(" 　您所填寫的內容不符合規則\n　要放棄您剛才對此項所做的更改嗎？", "您所編輯的內容不符合規則", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)

{

e.ExceptionMode = ExceptionMode.Ignore;

}

else

{

e.ExceptionMode = ExceptionMode.NoAction;

}

else

{

e.ExceptionMode = ExceptionMode.Ignore;

}

表單綁定數據集刷新GridView數據：

gv_zdfw.RefreshData();

gv_zdfw.RefreshRowCell(viewIndex.FocusedRowHandle, gv_zdfw.Columns["MDMZDFW_ZDBH"]);

gv_zdfw.RefreshRow(viewIndex.FocusedRowHandle);

GridView數據刷新表單綁定數據集：

gv_zdfw.CloseEditor();

分類: DEV

標簽: DEV
