It will not be better to prevent from double click(actually not double click,but submitting twice).
The better approch is to use unique constraints for combination of columns.If they will be inserted again,it will thrown a exception.

Hi,

Try disabling the button on first click or change the text from submit to submitting...with javascript

<input type="submit" id="btnSubmit" value="Submit"
   onclick="this.disabled=true;this.value='Submitting...'; this.form.submit();">

For the server side button,

OnClientClick call a java function which does this work of disabling and changing text.And onClick of the asp button, call the asp method you want.

hope this helps.
