Hello,
I've written a control that uses a RadComboBox in a modal popup that is initiated by an ajax toolkit PopupControlExtender. This works fine, however when I try to use it on a particular page in my website, the combobox doesn't behave normally and stops loading new items. The reason for this seems to be because the control has been placed inside an UpdatePanel.
If I show the modal popup automatically when the page loads then the combobox works fine - the issue only arises because the modal is hidden when the page first loads.
I understand that this is something to do with the scripts not being loaded for the RadComboBox, but I have no idea how to get around this. I've tried changing the UpdatePanel to a RadAjaxPanel but then nothing seems to work at all!
