Hi Taha,

Thank you for the image and the code provided.

As the default TextBox handles the KeyDown and KeyUp events, it is not possible to use a Custom Keyboard Command Provider, which usually is the way to go in such scenarios. What you need to do is handle the PreviewKeyDown event of the RadGridView and perform the logic for pressing the Up and Down keys inside.

I have created a sample project that implements the desired behavior. Please, review it and update me if such approach would be useful. 

I will be looking forward to your reply.

Regards,
