1.新建類庫解決方案，引入命名空間,同時引入要添加UI Form的WebPart(在Portal\UILib目錄下)


2.繼續UFSoft.UBF.UI.Custom.ExtendedPartBase，重寫AfterInit()方法，代碼如下，便于添加下拉列表按鈕，在原單據中UI先新增一下拉按鈕；添加按鈕綁定的父控件，如本例中的下拉列表控件，可以UBF設計工具中的控件名屬性ID來查找，本例中綁定的下拉列表按鈕：DropDownButton2，若是系統標準的單據，建議查看系統的源碼生成的ID相匹配

3.配置文件
配置文件WebPartExtend以作為前綴命名，如本例中：WebPartExtend_GiftDocUIPlug.config，配置內容如下
主要配置ExtendedPart節點屬性值
（1）parentPartFullName：引用的UIForm WebPart的dll
（2）extendedPartFullName：命名空間+類名

（3）extendedPartAssemblyName：程序集

<?xml version="1.0" encoding="utf-8" ?> <configuration><configSections><section name="WebPartExtend" type="UFSoft.UBF.UI.Custom.ExtendedPartSection, UFSoft.UBF.UI.FormProcess" /></configSections><WebPartExtend><ExtendedPart parentPartFullName="Homa.test.ch01.GifDocUIModel.GiftDocUIFormWebPart" extendedPartFullName="GiftDocUIPlug.GiftDocUIPlugExtend" extendedPartAssemblyName="GiftDocUIPlug.dll"></ExtendedPart></WebPartExtend> </configuration>

4.部署發布
(1)配置文件：拷貝至Portal根目錄下
(2)dll文件拷貝至Portal\UILib目錄下


5.最后運行下單據效果
