[Solved] Drop-down doesn't work when inside a ModalPopUp

[Jaime Fuhr]

I'm using the AJAX.NET ModalPopUpExtender to display a customer form.

Inside that form, I have a RadComboBox.  When the pop-up is opened, only the first comboBox item is available.  Clicking on the drop-down doesn't work.

As a test, I moved the comboBox outside of the modal and it works fine.  

Any ideas?

I found this article which solved my problem:  http://www.telerik.com/community/forums/aspnet-ajax/combobox/radcombobox-inside-an-ajaxtoolkit-modalpopupextender.aspx

The solution is to add the property "ZIndex="12000" to the comboBox.  

Now the dropdown shows up.  It must have been popping up behind my modal window, but because the list is short, I didn't notice it.
