DataBind a Control for another control

Question

I have two converters, one sets the visibility of the control to Hidden if the text is null. Another converts int to string. I am trying to use both of them below, I want to make the DockPanel Hidden if tbDisposition.Text is null, but the DockPanel binding does not work a bit.

<DockPanel Visibility="{Binding Path=tbDisposition.Text, Converter={StaticResource cIsVisible}}"> <TextBlock Text="Disposition: "/> <TextBlock Name="tbDisposition" Text="{Binding Path=SessionEvent.DispositionID, Converter={BLL:CodeMarkupExtension}}" Foreground="Blue" /> </DockPanel> 

Answer 1

You need to use ElementName :

 <DockPanel Visibility="{Binding ElementName=tbDisposition, Path=Text, Converter={StaticResource cIsVisible}}"> <TextBlock Text="Disposition: "/> <TextBlock Name="tbDisposition" Text="{Binding Path=SessionEvent.DispositionID, Converter={BLL:CodeMarkupExtension}}" Foreground="Blue" /> </DockPanel> 

Answer 2

When binding objects to the Text property, ToString() automatically called on this object, so there is no need for an int to string converter. Instead, you can simply override ToString.
