Exposing dataview

Posts: n/a
Hello all,

I have composite control with button, 2 textboxes and dataview.
Now I want to expose dataview control as propertie to be accessed at

I declared propertie:
public DataView myDataView
get { return localDataView}

on CreateChildControls I create localDataView as
localDataView = new DataView;
localDataView.ID = this.ID+"dataview";

All is ok, I see propertie myDataView in desiger, but when I click on
Columns propertie of my exposed dataview I get error
Object reference not set to an instance of an object.

Any ideas,

Best regards, Skok Tone
