Question

public void myTextBlock1_Tap(object sender, System.Windows.Input.GestureEventArgs e)
    {

        StackPanel mystack = new StackPanel() { Height = 100, Width = 200 };
        TextBlock myTextBlock1 = new TextBlock() 
            { Text = "Text Block", Width = 350, Height = 40, FontSize = 20,
              VerticalAlignment = VerticalAlignment.Center, 
              TextAlignment = TextAlignment.Center, 
              HorizontalAlignment = HorizontalAlignment.Center, };
        mystack.Children.Add(myTextBlock1);
    }


for (int r = 0; r < m; r++)
        {
            TextBlock myTextBlockr = new TextBlock() 
                { Text = "Text Block", Width = 350, Height = 40, FontSize = 20,
                  VerticalAlignment = VerticalAlignment.Center, 
                  TextAlignment = TextAlignment.Center, 
                  HorizontalAlignment = HorizontalAlignment.Center };

            if (r == 0)

            {
                myTextBlockr.Tap += new 
                   EventHandler<GestureEventArgs> (myTextBlock1_Tap);
            }
            stack1.Children.Add(myTextBlockr);
            myTextBlockr.Text = a[r];
        }

我想在创建文本块时动态触发事件。没有生成错误但是点击（或点击UWP）事件不会触发该功能。
