I need a javascript to either enable or disable the dropdowns when the user
clicks on the checkbox and do NOT post back to the server.
I tried the following, but it does not work. How to correct it?

AssignToQueueCheckBox.Attributes["oncheckedchanged"] =
"document.getElementById('ctl00$ctl00$ContentPlaceHolder1$ContentPlaceHolder2$WorkUnitDropDownList').disable=!document.getElementById('ctl00$ctl00$ContentPlaceHolder1$ContentPlaceHolder2$WorkUnitDropDownList').disable;"
+

Thanks

as there is no "oncheckedchanged" event for a checkbox, you are just defining
a custom attribute. try: "onclick"

also it really a bad practice to view source to get the control names, you
shouald ask the control for is ClientID:
