Question

我想对textblock tap事件进行一些编码，我需要它的文本值我的xaml就像下面的

    <ListBox x:Name="listBox1">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <StackPanel Height="auto" >
                    <TextBlock  Name="myTextBlock"  Text="{Binding Busnumber}"  Tap="buss_Tap"  />                     
                </StackPanel>
            </DataTemplate>
        </ListBox.ItemTemplate>

然后在文本块点击事件上，我想点击点击文本值

private void buss_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{        
    //i want to achieve this 
    // string aa= myTextBlock.text;
    //but this is not working so what to do here to achieve the same?
}

Answer 1

您将获得 TextBlock in sender parameter 。将它转换为Textblock并从那里获取文本：

string text = ((TextBlock)sender).Text;

Answer 2

试试这个：

private void buss_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
    TextBlock txt = (TextBlock)sender;
    MessageBox.Show(txt.Text);
}

从C＃（XAML）获取datatemplate内的textBlock文本
