Question

Grid data not updating based on text typed in TextBox

Answer 1

+1 A:

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.

Hello and thank you for the replythe text changed is firring when i do type along in the txtbox Private Sub cmdsearch(ByVal sender as Object, ByVal e as System.Windows.Controls.TextChangedEventArgs) Dim navn As String = DirectCast(Me.txtsearch.Text, String) 'convert our name collection to an IEnumerable(Of T) where T (type) = Person Dim source As IEnumerable(Of subscripers) = DirectCast(_SubscriperContext.subscripers, IEnumerable(Of subscripers)) Me.SubcriperGrd.ItemsSource = source.Where(Function(p As subscripers) p.Navn Like navn) End Sub

hmm strange how its formatted Private Sub cmdsearch(ByVal sender as Object, ByVal e as System.Windows.Controls.TextChangedEventArgs) Dim navn As String = DirectCast(Me.txtsearch.Text, String) Dim source As IEnumerable(Of subscripers) = DirectCast(_SubscriperContext.subscripers, IEnumerable(Of subscripers)) Me.SubcriperGrd.ItemsSource = source.Where(Function(p As subscripers) p.Navn Like navn) End Sub

I wasn't familiar with VB.NET's `Like` operator so I looked it up in the docs in MSDN (http://msdn.microsoft.com/en-us/library/swf8kaxw.aspx). I think that this is not the tool for the job as it appears to be for pattern matching (a very bare bones regex if you will). I think that you want `p.Navn.StartsWith(navn)`.

Oh, looks like you already figured that out.

@vbturbo: It's my pleasure. "and ill not bother the stack overflow forum ever again." Meh, ignore those that don't take you seriously; there's plenty of folks here that will. Just ask clear questions that haven't already been answered and there are plenty of people that will try to help you out. Good luck.

Answer 2

+1 A:

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

Nah, it just sounds funny => "lambada expressions" instead of "lambda expressions". Can't tell about others but I didn't want to offend you in any way. Welcome aboard and DO bother stack overflow forum again. It's a great resource to simplify your everyday development process. :)
