    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!

    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:

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