TabContainer in an Update Panel dissappears after an event is fired in an update panel

Hello :

I have a TabContainer in an Update Panel. When ever an event fires in an update Panel such as Button onclick , the TabContainer dissappears.

I also tried to move update Panel inside the TabPanel . I tested this at 2 different Places. One is on a Page and the other sits in a panel that is displayed by Modal Popup. When the event fires , the one in the Page is still visble and I have a JS error . The one that sits in the ModalPopup dissappears with same JS error.

Here is the error , I am seeing

this.get_element() has no properties

_app_onload(Object _disposableObjects=[9] _components=Object,Object _components=[9] _isPartialLoad=true)ScriptResource.ax... (line 217)

this.get_element().style.visibility = 'visible';

Can any please let me know how this problem can be resolved.

Thanks,

After little struggle , I found that TabstripContainer when in update Panel disappears.

For Ex i have this secnario :

<Page>

<updatepanel>

<usercontrol>

<TabStripContainer></TabstripContainer>

</usercontrol>

</updatepanel>

</Page>

The TabstripContainer in UserControl dissappears when an even fires in UserControl.

So i need to arrange the above as follows

<page>

<usercontrol>

<TabStripContainer>

<TabPanel>

<updatepanel

</updatePanel>

</TabPanel>

</TabstripContainer>

</usercontrol>

</page>

Hopefully this issue will be resolved. cause update panel is being used alot for partial rendering.

I have the same problem with TabContainer disappearing after a click on a button outside of it when both the TabContainer and the button are contained in an UpdatePanel.

Are there any solutions for this problem yet?

I must have the button in same UpdatePanel as TabContainer, but visually below the container.

Have you seen this thread:http://forums.asp.net/thread/1549317.aspx

Thank you very much! This fixes the bug! Sorry for not searching forums thoroughly enough.

So I understand that we need to modify Tabs.js dispose method

to dispose : function() {
Sys.Application.remove_load(this._app_onload$delegate); // this is missing
AjaxControlToolkit.TabContainer.callBaseMethod(this, "dispose");
}

But how are you explicitly using the TabContainer to use this Javascript. I am using AjaxControlKit.dll with no source code.

So what I did is I copied Tab.js into my project and modified the dispose method. And for the tabcontainer , I pasted the path to this Tab.js in

ScriptPath property7.But then I am getting a Type 'AjaxControlToolkit.TabPanel' does not have a public property named 'System.Web.UI.Control'.

What am i doing wrong here.

I took the sources of AjaxControlKit.dll and recompiled them after making the change in Tabs.js
Yep , basically , Jason Hill did the same thing.And it worked.
