How to specify javascript to run when ModalPopupExtender is shown *

Question

The ASP.NET AJAX ModalPopupExtender has OnCancelScript and OnOkScript properties, but it doesn't seem to have an OnShowScript property. I'd like to specify a javascript function to run each time the popup is shown.

In past situations, I set the TargetControlID to a dummy control and provide my own control that first does some JS code and then uses the JS methods to show the popup. But in this case, I am showing the popup from both client and server side code.

Anyone know of a way to do this?

BTW, I needed this because I have a textbox in the modal that I want to make a TinyMCE editor. But the TinyMCE init script doesn't work on invisible textboxes, so I had to find a way to run it at the time the modal was shown

Answer

hmmm... I'm pretty sure that there's a shown event for the MPE... this is off the top of my head, but I think you can add an event handler to the shown event on page_load

function pageLoad()
{
    var popup = $find('ModalPopupClientID');
    popup.add_shown(SetFocus);
}

function SetFocus()
{
    $get('TriggerClientId').focus();
}

i'm not sure tho if this will help you with calling it from the server side tho
