GridViewComboBox dynamic list

[Curtis]

I'm building a grid where a GridViewComboBox will have its list dynamically updated based on the selection of an item in a previous column.  I've read numerous posts about how to and how not to do this and they all make sense but I'm having one tiny problem that I cannot resolve (its because of my newness to this Grid I'm sure!)

 

Here's the code:

Private Sub ATGrid_EditorRequired(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.EditorRequiredEventArgs) Handles ATGrid.EditorRequired
   If ATGrid.CurrentColumn.Name.ToLower = "messagecodetype" Then
      If e.EditorType Is GetType(RadComboBoxEditor) Then
         RemoveHandler DirectCast(e.Editor, RadComboBoxEditor).ValueChanged, AddressOf Editor_ValueChanged
         AddHandler DirectCast(e.Editor, RadComboBoxEditor).ValueChanged, AddressOf Editor_ValueChanged
      End If
   End If
End Sub

See where it says "RadComboBoxEditor" ?  My Visual Studio 2017 code says, "RadComboBoxEditor not defined"

My form imports the following:

Imports Telerik.WinControls
Imports Telerik.WinControls.UI

but clearly this object is either not exposed or not found in either namespaces.  Can someone direct me to the correct namespace, please?

 

Thanks much!

-Curtis

Hello Curtis, 

Thank you for writing.  

I suppose that you use the latest version. Note that RadComboBoxEditor is replaced by a RadDropDownListEditor. I would recommend you to have a look at the following KB article which is quite useful on this topic: http://www.telerik.com/support/kb/winforms/gridview/details/cascading-comboboxes-in-radgridview

I hope this information helps. Should you have further questions I would be glad to help.
