GridViewComboBoxColumn dropdown item Height

[Curtis]

Is there any way to adjust the height of the items displayed when a GridViewComboBoxColumn is opened?  I'm not talking about the dropdownheight...I mean changing the height of each element inside the dropdown.

 

I'll be honest, I expected this column type to include a .ListElement property just like a RadDropDownList has but I've searched and cannot find a reference to this anywhere.

 

Any help you can provide would be appreciated.

After Frankensteining about 40 different pieces of code I came up with this:

Private Sub MCGrid_CellEditorInitialized(sender As Object, e As GridViewCellEventArgs) Handles MCGrid.CellEditorInitialized
    Dim ddl As RadDropDownListEditor = TryCast(e.ActiveEditor, RadDropDownListEditor)
    If ddl IsNot Nothing Then
        Dim editorElement As RadDropDownListEditorElement = TryCast(ddl.EditorElement, RadDropDownListEditorElement)
        editorElement.ListElement.ItemHeight = 25
        RemoveHandler editorElement.VisualItemFormatting, AddressOf editorElement_VisualItemFormatting
        AddHandler editorElement.VisualItemFormatting, AddressOf editorElement_VisualItemFormatting
    End If
End Sub

You don't need the Visual Formatting - my code snippet includes that reference because my dropdown list also displays an image.

Hello, Curtis,  

The CellEditorInitialized event is fired when the editor is initialized and visible. It is the appropriate place to introduce any customization to the editor. Adjusting the ItemHeight property of the ListElement is the correct way to increase/decrease the height. As you have already found out, it is possible to subscribe to the VisualItemFormatting event in order to customize the items in the drop down.

If you have any additional questions, please let me know.
