How to restrict user from submitting the form twice?
<p>I have an asp.net form, which allow users to submit a registration form which internally sends/store all these values on SharePoint list using the web-service and hence on submit the page process time is a little lengthier then the normal form.</p>

<p>Mean time before the page gets redirect to a thanks page, user's tend to click the submit button again, which is causing the multipul submission of the same record.</p>

<p>Please suggest a way to restrict this submission, on button click I am using a jquery function  for data validation, I have tried using the btn.disable = true method there, but once it reach's the else block (after passing the validation and this is where the disable = true code is) it doesn't submit's the form after reading btn.disable = true statement.</p>

<p>Experts, please show me a path.</p>

<p>Thanks in advance. </p>
