I am using an alert box to alert some messages after some validation.
Now I want to make alert box position over the control where it had a validation
error.

As a default, an alert box pops up in center of page,
Now I want it at some custom position,
for example I have 4 textbox to be validated, textbox-3 has some incorrect data,
I want the alert to be presented just above the textbox-3 instead of center of page.

Is this possible to change the display behavior of alert box?
If there's no other option to go for jquery dialog box.
