Hi Scott,
Thank you for the question.
There is a ValueChanged event that you can subscribe to. In your case the sender parameter will be a GridViewComboBoxCellElement which has a Value property. Use this property to take action appropriate to your situation.
I hope this is what you are looking for. Please write back if you have more questions.
All the best,

Hello jerry,
Thank you for your question. GridViewComboBoxCellElement is a type, not a property. You have to subscribe to RadGridView ValueChanged event and safely cast the sender reference to a GridViewComboBoxCellElement. If the cast is successful you can get the Value property of the casted object. Please write again if you have other questions.
Sincerely yours,

Victor,
When I try and cast sender I don't get an option for GridViewComboBoxCellElement.
I'm trying to do
GridViewComboBoxCellElement cmbCE = sender as GridViewComboBoxCellElement;
But it tells me that it doesn't exist. Am I missing something?
Thank You

Hi jerry,
Please excuse my colleague Victor for the naming error. Actually, the correct type of the combobox cell is:
GridComboBoxCellElement.
If you have additional questions, feel free to contact me.

I know this thread is a bit long in the tooth, but it was what I found for what I needed. I'm using VB.NET and here is what I have. It is failing with an InvalidCastException on Line 4 (DirectCast). What should I be doing to get the selected value?
1.
Private
Sub
dgvVenWarehouses_ValueChanged(sender
As
Object
, e
As
System.EventArgs)
Handles
dgvVenWarehouses.ValueChanged
2.
3.
Dim
cellElement
As
GridComboBoxCellElement
4.
cellElement =
DirectCast
(sender, GridComboBoxCellElement)
5.
value = cellElement.Value

Hello Bob,
Thank you for writing.
The RadGridView.ValueChanged event is fired when the editor's value is updated. The sender in this event is the editor, not the cell. However, note that the value is not committed to the cell yet until the user presses Enter or navigates to another cell. You can find below a sample code snippet demonstrating how to get the newly selected value and the corresponding displayed value:
I hope this information helps. Should you have further questions I would be glad to help.
