获得元素的名称上，我`clicked` /`mousedown` [英] get the name of the element on which I `clicked` / `mousedown`

问题描述

我的根元素是一个名为根图标的页面。

我有一个像<许多控制code>的TextBlock ，文本框，电网，矩形，边框等...谁是根。

的孩子

现在，我想有一个的MouseDown 或 PreviewMouseDown 或点击在根来找到我点击的元素的名称。

所以，我怎样才能得到我点击的元素的名称 / 鼠标按下？

如果我能得到一个使用隧道的解决方案，这将是容易得多。

解决方案

RoutedEventArgs 有获取或设置对引发事件的对象的引用属性源。试试这个

xaml.cs

 私人无效Grid_MouseDown_1（对象发件人，MouseButtonEventArgs E）
 {
 VAR mouseWasDownOn = e.Source为FrameworkElement的; 
如果（mouseWasDownOn！= NULL）
 {
串的ElementName = mouseWasDownOn.Name; 
} 
} 
  

XAML

 <电网PreviewMouseDown =Grid_MouseDown_1> 
<&StackPanel的GT; 
<组合框的ItemsSource ={绑定的ItemsSource}/> 
<按钮内容=OK/> 
< / StackPanel的> 
 
< /网格和GT;

I have a page whose root element is a Grid named Root.

I have many controls like TextBlock, TextBox, Grid, Rectangle, Border etc... who are children of Root.

Now, I want to have a MouseDown or PreviewMouseDown or Click on Root to find the name of the element on which I clicked.

So, how can I get the name of the element on which I clicked / mousedown ?

If I can get a solution that uses Tunneling, It will be much easier.

解决方案

RoutedEventArgs has property Source that Gets or sets a reference to the object that raised the event. Try this

xaml.cs

private void Grid_MouseDown_1(object sender, MouseButtonEventArgs e)
    {
        var mouseWasDownOn = e.Source as FrameworkElement;
        if (mouseWasDownOn != null)
        {
            string elementName = mouseWasDownOn.Name;
        }
    }

xaml

<Grid PreviewMouseDown="Grid_MouseDown_1">
    <StackPanel>
        <ComboBox ItemsSource="{Binding ItemsSource}"/>
        <Button Content="ok"/>
    </StackPanel>

</Grid>
