UWP入門（八）--幾個簡單的控件原文:UWP入門（八）--幾個簡單的控件

每天看幾個，要不聊幾天我就可以看完啦，加油！

看效果

1. CheckBox

<TextBlock Grid.Row="0" Text="CheckBox" VerticalAlignment="Center" /><StackPanel Grid.Column="1"Margin="20,10,0,10" Orientation="Horizontal"><CheckBox Name="MyCheckBox" Content="Agree?"Tapped="MyCheckBox_Tapped" /><TextBlock Name="CheckBoxResultTextBlock" /></StackPanel> private void MyCheckBox_Tapped(object sender, TappedRoutedEventArgs e){CheckBoxResultTextBlock.Text = MyCheckBox.IsChecked.ToString();}

2. RadioButton

<TextBlock Grid.Row="2" Text="RadioButton" VerticalAlignment="Center" /><StackPanel Grid.Row="2" Grid.Column="1" Orientation="Horizontal"Margin="20,10,0,10"><RadioButton Name="YesRadioButton" Content="Yes" GroupName="MyGroup" Checked="RadioButton_Checked" /><RadioButton Name="NoRadioButton" Content="No" GroupName="MyGroup" Checked="RadioButton_Checked" /><TextBlock Name="RadioButtonTextBlock" /></StackPanel> private void RadioButton_Checked(object sender, RoutedEventArgs e){RadioButtonTextBlock.Text = (bool)YesRadioButton.IsChecked ? "Yes" : "No";}

3. CombomBox

<TextBlock Grid.Row="3" Text="ComboBox" Name="MyComboBox" VerticalAlignment="Center" /><StackPanel Orientation="Horizontal" Grid.Row="3" Grid.Column="1" Margin="20,10,0,10"><ComboBox SelectionChanged="ComboBox_SelectionChanged" ><ComboBoxItem Content="Fourth" /><ComboBoxItem Content="Fifth" /><ComboBoxItem Content="Sixth" IsSelected="True" /></ComboBox><TextBlock Name="ComboBoxResultTextBlock" /></StackPanel> private void ComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e){if (ComboBoxResultTextBlock == null) return;var combo = (ComboBox)sender;var item = (ComboBoxItem)combo.SelectedItem;ComboBoxResultTextBlock.Text = item.Content.ToString();}

4. ListBox

<TextBlock Grid.Row="4" Text="ListBox" VerticalAlignment="Center" /><StackPanel Grid.Row="4" Grid.Column="1" Margin="20,10,0,10"><ListBox Name="MyListBox" SelectionMode="Multiple" SelectionChanged="ListBox_SelectionChanged"><ListBoxItem Content="First" /><ListBoxItem Content="Second" /><ListBoxItem Content="Third" /></ListBox><TextBlock Name="ListBoxResultTextBlock" /></StackPanel> private void ListBox_SelectionChanged(object sender, SelectionChangedEventArgs e){var selectedItems = MyListBox.Items.Cast<ListBoxItem>().Where(p => p.IsSelected).Select(t => t.Content.ToString()).ToArray();ListBoxResultTextBlock.Text = string.Join(", ", selectedItems);}

5. image

image 的四種拉伸方法

None
- 不做任何處理，一般比較大
Fill
- 占據所給的最大空間，比例會失調
Uniform
- 按比例伸縮，占據所給的最大空間
UniformFill
- 按比例伸縮，占據大小

6. 漂亮的 ToggleSwitch

不需要代碼

7. ToggleButton

<TextBlock Grid.Row="7" Text="ToggleButton" VerticalAlignment="Center" /><StackPanel Orientation="Horizontal" Grid.Row="7" Grid.Column="1" Margin="20,10,0,10" ><ToggleButton Name="MyToggleButton" Content="Premium Option" IsThreeState="True" Click="MyToggleButton_Click" /><TextBlock Name="ToggleButtonResultTextBlock" /></StackPanel> private void MyToggleButton_Click(object sender, RoutedEventArgs e){ToggleButtonResultTextBlock.Text = MyToggleButton.IsChecked.ToString();}

代碼

cs 代碼

public sealed partial class MainPage : Page{public MainPage(){this.InitializeComponent();}private void MyCheckBox_Tapped(object sender, TappedRoutedEventArgs e){CheckBoxResultTextBlock.Text = MyCheckBox.IsChecked.ToString();}private void RadioButton_Checked(object sender, RoutedEventArgs e){RadioButtonTextBlock.Text = (bool)YesRadioButton.IsChecked ? "Yes" : "No";}private void ComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e){if (ComboBoxResultTextBlock == null) return;var combo = (ComboBox)sender;var item = (ComboBoxItem)combo.SelectedItem;ComboBoxResultTextBlock.Text = item.Content.ToString();}private void ListBox_SelectionChanged(object sender, SelectionChangedEventArgs e){var selectedItems = MyListBox.Items.Cast<ListBoxItem>().Where(p => p.IsSelected).Select(t => t.Content.ToString()).ToArray();ListBoxResultTextBlock.Text = string.Join(", ", selectedItems);}private void MyToggleButton_Click(object sender, RoutedEventArgs e){ToggleButtonResultTextBlock.Text = MyToggleButton.IsChecked.ToString();}} posted on 2017-09-20 13:16 NET未來之路閱讀(...) 評論(...) 編輯收藏
