[Sirwan]

Hi 
i want to hide a column based on a parameter value.
First: i can't figure out the expression i should write in group filter.
Second : i should adjust the other columns width, will this code do the job
Private Sub Table1_ItemDataBinding(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Table1.ItemDataBinding
        Table1.Body.Columns(index).Width = NewSize
End Sub
