Hi,

My requirement is
I have an asp page in which there is a textbox. If the user clicks on close(X) button in IE without entering a value in the textbox I want a pop up to appear like "Please enter the value" and the window should not close. Kindly advoice.

I don't want the browser confirmation with Ok and cancel. B'coz if the user clicks on OK the window will close.

regards,
...
