how to bind width of child element to width of parent element in silverlight

Question

I have a grid whose width is \"1*\". So the actual width decided at runtime I think. Within that grid I have another grid whose width I want to set to the runtime width of paren

Answer 1

This is generic solution which may work everywhere. You wouldn't need to write parent element name. This will identify its parent and will take parent's width.

Width="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=ActualWidth}"
