get text from a TextBox

Question

Hello,

I'm trying to develop a Windows 8 app, and in the process used blend to add some Textboxes to the UI in XAML. However, I want to eventually get the text the user has imputed into the boxes, and use it in C#. Is there a way to easily do this? I've been looking for online, and it seems sort of like the opposite of data binding, and I haven't had a lot of luck looking around for an answer to this question.

Thanks for the Help!

Hi DrakeTX,

Well, first step you need assign a x:Name for a TextBox control:

 <TextBox x:Name="txt" HorizontalAlignment="Left" Height="194" Margin="337,210,0,0" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top" Width="350"/>

second step, get the Text from cs:

        public MainPage()
        {
            this.InitializeComponent();
            string text = txt.Text;
        }

Thanks for the help James!

This makes sense, but I'm having a bit of difficulty implementing this as when I do, I get a The Name does not exist in the current context error.  Right now, the Textboxes were generated by blend in a DataTemplatein App.xaml

<DataTemplate x:Name="PostAnEventBlocks" x:Key="DataTemplate1">
      	<Grid>
	<TextBlock HorizontalAlignment="Left" Width = "200" Margin="14,10,0,487" FontSize="25">Event Name</TextBlock>
      	<TextBox Name="EventNameTextBox" HorizontalAlignment="Left" TextWrapping="Wrap" VerticalAlignment="Top" Width="186" Margin="14,71,0,0"/>
			
      	</Grid>
      </DataTemplate>

where the DataTemplate is called in MainPage.xaml

<HubSection x:Name="PostAnEventSection" Header="Post An Event" DataContext="{Binding MainViewModel.PostAnEventModel}" ContentTemplate="{StaticResource DataTemplate1}" IsHeaderInteractive="{Binding HasMoreItems}" Style="{StaticResource AppHubSectionStyle}" Width="642" 
             />

Is there a arrange this so that the TextBoxes can be more easily edited? I seriously doubt that the DataTemplate is in the right place, or the right format for what I really need.

Thanks for all of the help!
