我的代码在 .cs 文件中定义的函数调用上生成面板。代码中使用了 ItemControl 来生成这些 Panels 。每个面板都有它Textbox
的 Slider
和Combobox
。
每个 Panel 的 Slider 和 Combobox 都在使用 TextBox.Text 像:
增加 Textbox.Text 字体大小的滑块。
组合框选择 TextBox.Text 的对齐方式。
我想将 Combobox 替换为 Button 和 Content Left
。因此,当我单击 Button 时,它的 Content 必须更改为Right
,类似地从 更改Right
为Left
.,才能更改为Alignment
.
谁能解决我的问题?这里的代码是:
XAML 文件:
<ItemsControl x:Name="lstItemsClassM" >
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<ComboBox x:Name="cboOccupation" IsEditable="False" HorizontalAlignment="Left"
Text="{Binding Path=Alignment, Mode=TwoWay}"
Margin="4" Width="140">
<ComboBoxItem>Right</ComboBoxItem>
<ComboBoxItem>Left</ComboBoxItem>
</ComboBox>
<Button Content="{Binding Alignment, Mode=TwoWay}" Click="Button_Click" Tag="{Binding PKId}" SourceUpdated="Button_SourceUpdated" />
<TextBox x:Name="txtText" Width="300" Height="100" Text="{Binding Text;, Mode=TwoWay}" FontSize="{Binding FontSize, Mode=OneWay}" TextAlignment="{Binding Alignment, Mode=OneWay}" />
<Slider Minimum="10" Maximum="30" Value="{Binding FontSize, Mode=TwoWay}" />
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
