I have a RadGrid with 3 columns in the master table only: 2 are read only and the other is an EditTemplate with a RadTextBox. If in edit or insert mode and after the value of the textbox changes and loses focus, I want to do an AJAX call which will query the database for the newly entered value and then populate the 2 read only fields from the results. So to the user, the 2 read only fields appear to get "auto populated" after the value of the textbox changes. Is this possible? All I really need help with is getting the textbox to call a sub in the codebehind. I should be able to take it from there.
Thanks!
Thanks!
