Have you tried to collapse/show columns instead of unload and load items of DataGrid? I think it's more efficient. Like this: Private Sub menuItem_Checked(sender As Object, e As RoutedEventArgs)Dim item As MenuItem = TryCast(sender, MenuItem)SetItemVisibility(item, Visibility.Visible)End Sub Private Sub SetItemVisibility(ByRef item As MenuItem, ByVal visibilidad As Visibility) If item IsNot Nothing Then For Each columna As DataGridColumn In _dataGrid.Columns If columna.Header.ToString.Equals(item.Header.ToString) Then columna.Visibility = visibilidad Exit For End If Next End If End Sub

Hello Diptimaya, This was a wonderful article and helped me a lot!!I think there is some logical error in menuItem_checked Event.As the MenuItem item variable is not used in the event and hence isChecked is always set to true. Hope u would notice!!!!! Again thanks

Do you have a net4 VS2010 update to this topic? I can't seem to convert this, as I get errors with the DataGridColumnHeaders under net4.0 using Microsoft.Windows.Controls.Primitives. It compiles fine under 3.5, but not 4.0. What is the equivalent Net4 code? Thanks, Jeff
