How to perform a server-side validation using ASPxCallback and if succeed, make a full page postback
This example demonstrates how to perform a server-side validation using the ASPxCallback control and to make a full page postback if the validation is successful.
Clicking the check button initiates a callback on the server to perform a server-side validation. If the validation succeeds, in the client's CallbackComplete event handler the button click initiates a full page postback.
