Context menu paste in textbox not updated binding element value

Question

I'm binding a text box to a textblock, but it is not updated when I paste something using the context menu.

Following there is the XAML code for element binding:

<uc:CustomTextBox x:Name="txtBoxLastName"
                  Grid.Row="3"
                  Grid.Column="1"
                  Width="80"
                  Height="25"
                  HorizontalAlignment="Left" />

<TextBlock Grid.Row="4"
           Grid.Column="1"
           Width="100"
           Height="100"
           Text="{Binding Text,
                          ElementName=txtBoxLastName}" />

Context menu paste code:

this.SelectedText = Clipboard.GetText();

What's wrong with this code? Is there any other way to do the same ?

Regards.

Answer 1

Using the common Silverlight controls, the text pasted in the TextBox control is automatically pasted also in the TextBlock control.

I think the problem is in the code you're using to paste the text stored in the Clipboard, because you're setting the property SelectedText, when instead your TextBlock's Text property is bound to the Text property of the TextBox.

You can change the line from:

this.SelectedText = Clipboard.GetText();

to:

this.Text = Clipboard.GetText();

or, as second option, change the binding in your textblock from this:

Text="{Binding Text, ElementName=txtBoxLastName}"

to this:

Text="{Binding SelectedText, ElementName=txtBoxLastName}"
