如何Rais GotFocus RoutedEvent并将其捕获到另一个控件中 [英] How to Rais GotFocus RoutedEvent and catch it in an other control

问题描述

你好

我的VisualTree看起来像这样:

my VisualTree looks something like that:

DesignerItem
+ VertexControl

DesignerItem
+VertexControl

顺便说一句.

//Create a DesignerItem to make the VertexVisualization moveabel
DesignerItem designerItem = new DesignerItem();

VertexVisualization vertexcontrol = new VertexVisualization();
vertexcontrol.Vertex = v;
//add the VertexVisualization to the DesignerItem
designerItem.Content = vertexcontrol;

Canvas.Children.Add(designerItem);

推荐答案

您好martin.doku，

Hi martin.doku,

您是否将Focusable属性设置为true，我尝试使用以下代码来再现您的问题:

Have you set the Focusable property as true, i tried to repro your issue with below code:

<Canvas Background="Transparent" Width="500" Height="500">
    <ListBoxItem Focusable="True" Width="200" Height="20" Name="contentcontrol" GotFocus="contentcontrol_GotFocus">
        <TextBlock Focusable="True" Width="50" Height="20" Text="test" GotFocus="TextBlock_GotFocus"/>   
    </ListBoxItem>
</Canvas>
