Handle Double-click on <Input type="image">

I have an image "button" which causes a postback.

I handle the "click" with

If Request.Form("btnBU7WD6_Submit.X") > 0 Then...

this works great. However, when a user double-clicks the image button the
Page_Load (postback) is processed twice. This is a problem.

Is there any easy way to detect that the image button has been double-cliked
and posted back twice?

Try creating a boolean Session Item at thee end of the click handler method
, and check for its presence before handling any subsequent clicks. If the
session item is not null at the beginning of the click handler method body,
that means it was already clicked.

Thanks Peter. That's the solution I planned on going with.

I was hoping there was a way to detect it in the Postback, but I don't see
anything.

Thanks

Disable the button client side onclick?
