how to disable the button when submitted

Hi,

When click on button, you have to disable the control.



in JavaScript, you have to write the following:

function SubmitResult()
{
  document.getElementById('btnSubmit ').disabled = true;
  __doPostBack('btnSubmit','click');
}

It will identify the click event of the server side.

protected void btnSubmit_Click(object sender, eventargs e)
{
        
}

 First of all you must have PRIMARY KEY CONSTRAINT to avoid duplicates. Or must have a duplicate check before insertion.
