When you drag the RadDock control on the client, it is moved through the DOM. So if you update a RadDock via AJAX you will receive such an error.

There several approaches to use RadDock with AJAX
1) You can update only the content in a RadDock, e.g.
http://demos.telerik.com/ASPNET/Prometheus/Dock/Examples/Default/DefaultCS.aspx
2) You can update all RadDockZones while all RadDocks are docked ,e.g.
http://demos.telerik.com/ASPNET/Prometheus/Dock/Examples/AutoPostBack/DefaultCS.aspx
3) As it shown in the following example
http://demos.telerik.com/ASPNET/Prometheus/Dock/Examples/MyPortal/DefaultCS.aspx

Hope this helps!

Else

False

rddockzonePrjTypes.Visible =

False

End If

Hi Priya,

The problem you experience is most probably due to making the RadDocks invisible. When the RadDock's Visible property is set to false the control is not rendered on the page and it is possible in case of a callback this results in the error you mention. My suggestion is to close the docks instead of making them invisible. In this way you will be able to have the closed docks in the state with closed status. You could show them later when you need them. You could close the docks if you set the RadDock's Closed property to true.

In case you still experience any problems, please, send us a simple running project which reproduces the problem you describe so that we can run it on our side, get a better idea of your scenario and research the issue. You will need to open a support ticket in order to have the right to attach files. For your convenience I have attached a screenshot from you own account with instructions how to open a support ticket. I would also like to ask you for a detailed description of what is the exact scenario you want to achieve. We will be glad to help you resolve the problem.

I receive the same error message when using radajaxmanager ina moss webpart, i followed every guide in the site, but cant get it to work. Im trying to set a radcalendar to do assinc. postbacks, setting this on prerender:

 

 

RadAjaxManager ajaxManager = RadAjaxManager.GetCurrent(this.Page); ajaxManager.AjaxSettings.AddAjaxSetting(calendario, calendario);

when i try the radajaxpanel, it just doesnt work...

 

 

[TerraForum]

I got around the first issue (placed radcalendar inside a Panel), bt now it only work in the first postback, the calendar does not do a second postback anymore...

[Missing User]

Hello TerraForum,


I'd suggest that you temporarily disable Ajax on your page (set EnableAjax=False) and make sure that your approach works with PostBacks. This is a good debugging approach to take when you're concerned that Ajax is causing problems.

All the best,

as a matter of fact, i gave it up using RadControls for ASP.NET AJAX, and used RadControls for ASP.NET, that caused no problems for me...

[caglar_ozkul]

Hi,
I have an asp Panel that contains 10 field. and a toolbar has been located on the panel (out of panel)

When I use the following code, 

protected void page_Load(object sender, EventArgs e)
{
    AjaxProxy.AddAjaxSettings(toolbar1, panel1);
    AjaxProxy.AddAjaxSettings(field1

, field2);

 

 

     AjaxProxy.AddAjaxSettings(field4, field5

);
}

after clicking the toolbar, field2 and field5 becomes invisible. And in the second click it gives me the error: Could not find updatepanel ctl00_.....field2 ....

Kind Regards,
Caglar Ozkul

Hello caglar_ozkul,

Keep in mind that the controls, which Visible property is set to False, are not rendered on the page. This can be the reason for catching the error. For better understanding of the problem we have to reproduce it locally, but the information, that you provided is insufficient. Can you,please, send us running project, where we can observe this issue? Once we receive it, we will do our best to help you.

Sincerely yours,
Petko
