What I'm looking to do is popup an "are you sure" confirmation box if the newly selected value of a dropdownlist is a certain value before I submit the form.
<select name="ListSearchType" id="ListSearchType">
<option value="C">Closed</option>
<option value="O">Open</option>
<option value="P">Pending</option>
</select>
So if I had the dropdownlist like above with autopostback enabled, I'd want to popup a confirmation box if the user select 'Closed' before the form is submitted.
