Question

I have a User Control, let’s say TextboxPage and it’s associated with ViewModel, TextboxPageViewModel. I need to get reference of TextboxPage in TextboxPageViewModel.

i.e.

<Button x:Name="btnCustomer" 
Command="{Binding CustomerCommand}" 
CommandParameter="{Binding...?}"/>

How can I do binding in xaml to pass the reference of UserControl, TextboxPage?

Answer 1

This will work in your case:

<Button x:Name="btnCustomer" 
Command="{Binding CustomerCommand}" 
CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"/>

cheers!
