Why Popup Calendar doest trigger textbox event OnTextChanged?

A textbox connect to an Atlas Toolkit Control PopupCanendar.
There is a javascript for OnTextChanged event of this textbox.

When using popup calendar to select a date for this textbox, it doesn't trigger this event.
But if type date in textbox directly, it is OK. the OnTextChanged will be fired.

Why? what's the solution for this case?The DOM is a little weird in that script changes don't tend to fire the associated event handlers that get fired when the user makes a change. It sounds like you're hitting that here. It's possible to fire the event from script, too, so maybe you want to try that. If you switch to PopupControl's CommitScript mode, I think you should be able to make this change fairly easily.

window.opener.document.TextBoxRateLockDate is null or not an object

My ASP.Net page has a calendar picker link with an onclick event as shown below:

<a href="http://links.10026.com/?link=javascript:;" onclick="calendarPicker('TextBoxRateLockDate');" title="Pick Date from Calendar"><img src="http://pics.10026.com/?src=../../../../App_Images/simplecalendar/calendar.gif" border="0" /></a>

The above link is inside of a MultiView control, which is inside an UpdatePanel control. The link pops-up the date picker calendar just fine but when I select a date , I get the following error:

Microsoft Jscript runtime error:
'window.opener.document.TextBoxRateLockDate' is null or not an object

How can I resolve this issue?

Hi,

This is a pure javascript issue.

I'd suggest using document.getElementById() method to find the textbox. Usually like this: window.opener.document.getElementById("TextBoxRateLockDate")

Hope this helps.
