Silverlight 4.0 TextBlock

Question

Can some one send me a tutorial with textblock .

Im trying to give the user the ability to write in the textbox during runtime. At the moment its not letting me
write in the textbox.



Also I am trying to put a border around the textblock, below when i add the border element around the text block
It puts the border around the grid itself.

Can someone assist me?

<Border>
   <TextBlock Height="108"   HorizontalAlignment="Left" Margin="15,44,0,0" Name="UutHeaderInformationTextBlock" Text="Uut Header Block Information" VerticalAlignment="Top" Width="500" TextWrapping="Wrap" DataContext="{Binding}" />

</Border>
