Disabling SUBMIT button to prevent multiple clicks.

Experts,

I have a .NET applicataion form that is called form a Master page. The application's SUBMIT button needs to NOT allow multiple clicks.

I have tried this in the Page_Load event and verified it's added:

btnSubmit.Attributes.Add("onSubmit", "this.disabled=true;this.value='Please wait...';this.form.submit()");

but it's still allowing multiple clicks and multiple submissions.

Any ideas?

Thanks.

You do NOT want to disable the submit then submit the form..
there is no onsubmit on a button, it is on the form.
onclick is what you wanted

perhaps this is what you want

<script>
var submitted = false;
</script>

and add onsubmit of the form
if (submitted) return false; submitted=true;

or something like

btnSubmit.Attributes.Add("onclick", "if (this.form.getAttribute(submitted)) return false;
this.form.setAttribute('submitted',true); this.value='Please wait...'");

mplungjan,

Thanks for the catch, I did mean for it to be "onClick" on the button.
After correcting that (at least the behavior changed), the button is disabling (greying out) and the text is changing (Please Wait...), but the form is not submitting. It postsback like there is validation errors and there's not.

As I said. You cannot disable the submit button when you submit.

Instead set a switch and test it

Thanks.
