[DevExpress Support Team: MOVED FROM Detect when ENTER key is pressed in a grid]
[I need to detect when the enter key is pressed in a grid view. Subscribing to the keydown event, I can get all the other keypress events but the event is not triggered when pressing the ENTER key. The grid that I'm displaying is readonly mode]
How can this be done in WPF?

Hi Isaac,
I have attached a sample project illustrating how to accomplish this task. Please take a moment to review it.
Thanks,

Hello Jan,

Elliot's approach is based on handling the following TableView events: RowUpdated and HiddenEditor. These events are raised when an active cell is closed. In fact, this happens when an end-user presses Enter.

Although, there is another approach to accomplish this task using the standard WPF Preview_ events:

XAML
...  
<dxg:GridControl.View>  
    <dxg:TableView PreviewKeyDown="OnPreviewKeyDown" ... />  
</dxg:GridControl.View>

C#
void OnPreviewKeyDown(object sender, KeyEventArgs e) {  
            if(e.Key == Key.Return) {  
                // ...  
            }  
        }

I hope you will find this information helpful. Let me know your results.
