Grid data not updating based on text typed in TextBox

I have this lambda expression

Me.Subcripe开发者_如何学CrGrd.ItemsSource = _
   source.Where(Function(p As subscripers) p.Navn Like navn)

where i should filter the grid data based on the typed input in a txtbox

It returns the result when i type the full name but it doesn't filter the data as i type along in the txt field

what am i missing ?

Thanks

Sorry for asking (seems like i must be a jerk according to some of the response)

here is the solution

Me.SubcriperGrd.ItemsSource = source.Where(Function(p As subscripers) p.Navn.StartsWith(navn))

in case someone else might look for a filter solution

and ill not bother the stack overflow forum ever again

You're probably missing responding to the event sent when the text changes TextBox.TextChanged. Handle this event and update the filter each time the text changes.
