Issue with Image loading in Ajax

Hi All,

We have issue with image loading while using AJAX

- We are using UpdatePanel to validate the request.

Issue:

On page load below code is working fine.

imgVefrification.ImageUrl = "ImageValidate.aspx";

On button click after validating the image value, if validation fails we are trying to call it again.

But image is not getting refreshed (Debug is not hit/process "ImageValidate.aspx" page)

Please suggest.
