Hello Lakshmi Satish Kumar Pydipati,
It seems you have hit a known issue in RadGridView . The RadGridView takes more control than needed over the Tab key navigation thus making scenarios as yours hard to achieve.
We are currently working on fixing that problem . Meanwhile as a workaround I may suggest to block the RadGridView from handling Tab Key and programmatically set focus to the next TextBox.
You may block the RadGridView from stealing the Tab key with the following code :
/assuming that you have subscribed to the KeyDown event of your textboxes)
.RadGridView1.ItemsSource = GetPersons();
sender, KeyEventArgs e)
(e.Key == Key.Tab)
Please excuse us for the inconvenience caused. We are doing our best to provide a fix as soon as possible.
