Dynamic generated Controls doesnt work, javascript error

I have an ajax enabled control which has a Dropdownlist that changes the Textbox when index gets changed. It is working fine if I use an ASPX page that contains the control in design time.

However, when I dynamically add this control to the ASPX in run time, I got an error when the Dropdownlist is triggered:

Javascript error: System.InvalidOperationException: A control with ID 'myDropDownList' could not be found for the trigger in UpdatePanel..etc..

What should I do? Please help..

There's a good chance that if you look at your page source you'll find that the dynamic control does not have a clientside Id of 'myDropDownList'. It'll probably have something more complex like ct100_myDropDownList or something.

Two possible fixes: 1) wire up your javascript on something other than the id (e.g. iterate over getElementsByTagName), or 2) render the control's ClientID inside a script tag on the page like: var ddl = '<%= myDropDownList.ClientID %>'

HOpe that helps.

DropshadowExtender disappear on gridview selected index changes

Hello,

I have a gridview inside a panel wich is inside an updatepanel. My problem is when I click on my gridview and I select a row the shado and the rounded corners of the panel around the gridview disappear.

I can see the dropshadowextender, only on the first page load, after it disappears. I can't find any solution to keep the rounded corner and the shadow

Please try your scenario with the recently available61121 release of the Toolkit (and ASP.NET AJAX Beta 2). If the problem persists, then please reply with acomplete, self-contained sample page that demonstrates the problem so that we can investigate the specific behavior you're seeing. Thank you!

DropDownList inside an UpdatePanel

Hi

When i change the DropDownList value, the Text property doesn't change and the selected index is still at 0.
