我的问题是,当用户单击FirstUserControl上的Button时,我想从UserControl(FirstUsercontrol)将Textbox值传递到不同的UserControls文本框(SecondUsercontrol)。 我在互联网上搜索了很多,发现了link。
然而,我的问题仍然存在,我真的不知道如何解决这个问题。 如果我按照链接上提到的方式进行操作,我的SecondUsercontrol将从FirstUserControl获取所有内容,我只想将Textboxvalues传递给UserControl。
First UserControl.xaml.cs:
public partial class FirstUserControl: UserControl, INotifyPropertyChanged
{
public FirstUserControl()
{
//this.DataContext = this;
InitializeComponent();
}
public string ThemaString
{
get { return (string)GetValue(ThemaStringProperty); }
set { SetValue(ThemaStringProperty, value); }
}
// Using a DependencyProperty as the backing store for ThemaString. This enables animation, styling, binding, etc...
public static readonly DependencyProperty ThemaStringProperty =
DependencyProperty.Register("ThemaString", typeof(string), typeof(sseAnzeigen), new FrameworkPropertyMetadata(null) { BindsTwoWayByDefault = true });
FirstUserControls.xaml:
<Label Content="Thema:" Grid.Column="0" HorizontalAlignment="Left" Margin="3" Grid.Row="8" VerticalAlignment="Center"/>
<TextBox x:Name="ThemaText" Grid.Column="1"
HorizontalAlignment="Left" Height="23" Margin="3" Grid.Row="8"
Text="{Binding ThemaString, RelativeSource={RelativeSource
AncestorType={x:Type local:FirstUserControl}}/>
<Button Content="Entwurfsansicht" Grid.Row="3"
Click="Button_Click" />
SecondUsercontrol.xaml.cs:
<UserControl.DataContext>
<local:FirstUserControl/>
</UserControl.DataContext>
<TextBlock Text="Thema:" MinWidth="{Binding ActualWidth,
ElementName=textBlock, Mode=OneWay}" />
<TextBox x:Name="ThemaText" Text="{Binding ThemaString}">
我试图将代码剪切成我的问题。希望这足以理解我的意思:)。 谢谢!!
