You should be able to subscribe to the tapped event for the control. It is document <a href="http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.xaml.uielement.tapped" rel="nofollow">here</a>

It cannot be simpler. As dotNetNinja says you have to sign up for the Tapped event. Example follows, notice TextBox_Tapped method in the xaml code and in the cs code behind.

.xaml code:

<pre><code>&lt;Page x:Class="TappedEventExample.BlankPage"
 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 xmlns:local="using:TappedEventExample"
 xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
 xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
 mc:Ignorable="d"&gt;
 &lt;Grid Background="{StaticResource ApplicationPageBackgroundBrush}"&gt;
 &lt;TextBox
 x:Name="MyTextBox"
 HorizontalAlignment="Left"
 Margin="100,100,0,0"
 TextWrapping="Wrap"
 Text="My TextBox"
 VerticalAlignment="Top"
 Height="100" Width="200"
 Tapped="TextBox_Tapped"/&gt;
 &lt;/Grid&gt;
&lt;/Page&gt;
</code></pre>

.xaml.cs code:

<pre><code>public sealed partial class BlankPage : Page
{
 public BlankPage()
 {
 this.InitializeComponent();
 }

 /// &lt;summary&gt;
 /// Invoked when this page is about to be displayed in a Frame.
 /// &lt;/summary&gt;
 /// &lt;param name="e"&gt;Event data that describes how this page was reached. The Parameter
 /// property is typically used to configure the page.&lt;/param&gt;
 protected override void OnNavigatedTo(NavigationEventArgs e)
 {
 }

 private void TextBox_Tapped(object sender, TappedRoutedEventArgs e)
 {
 this.MyTextBox.Text = "I was tapped.";
 }
}
</code></pre>

That's all.

How do i detect if the textbox has been tapped. User will normally tap on the textbox before they can type something. I tried textbox.tapped = true , .selected , it doesnt work for WinRT/Windows 8 metro application. Can someone help me out? THanks

如何检测文本框是否已被点击。用户通常会在键入内容之前点击文本框。我尝试了textbox.tapped = true，.selected，它不适用于WinRT/Windows8 metro应用程序。有人能帮帮我吗？谢谢
