Javascript - Validate DropDownList If Checkbox Checked?
Aug 31, 2010
ASP.NET3.5 Webforms. Am trying to put a validator on the drop down list, only if the checkbox is checked.
This doesn't work. If I put an alert in the onclick event, it does show.
<script language="javascript" type="text/javascript">
function setVal(sender) {
var myVal = document.getElementById('<%=(DropDownList)CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("ddlSupplierCouncilArea")%>');
