I don't know what exactly can be wrong because I reviewed my code it seems all looks quite good. Also I used same functionality with RadControls for asp.net it working good, and when migrated to the RadControls for ASPNET AJAX I encountered with such problems in forms where used rad ajax. And in some scenariuos it works fine, but sometimes crashes hard to predict when and why it crashes.
So maybe you could help me with that problem.
I can only copy code of one of my forms where I getting exception, because whole system is hudge enough. I am using ms web clint factory for client and for services web service factory. Is it can affet somehow ajax ?
So here it is code of one form:
Aspnet:

Hello Raimondas,

From your code snippets I see that you commented an MS UpdatePanel instance and replaced it with RadAjaxPanel. Do you receive the same error with the UpdatePanel? I am asking this question because our RadAjaxPanel is based on it and the exception might be rather a generic one with this configuration.

If the problem surfaces only when using our RadAjaxPanel, the best means to progress in our investigation is to isolate a stripped working version of your project and send it enclosed to a formal support ticket. We will examine your complete code logic and will get back to you with more info on the matter.

Best regards,

The same issue here. Standard UpdatePanel works but RadAjaxPanel always fails. To reproduce:
Add RadAjaxPanel to standard FormView EditTemplate. And bind values to FormView.
First time you hit edit state of FormView everything go ok. But If you try to bind new values, then same error as above occurs.

Hello Marian,

Indeed you are correct about this behavior. I suspect that it is caused by the fact that every control which implements IScriptControl should be registered with the ScriptManager, however when this control is moved to another control's collection (in your case when the FormView is rebound) the ScriptManager "registration" is not updated, which points to the control which do not exists anymore. In order to workaround this behavior you can update the entire FormView control or you can use RadAjaxManager and set the ajaxsetting for the nested control on Page's PreRender event. I have attached a simple page which demonstrates this later approach.
Please give ti a try and let us know if this helps.

All the best,
Rosen

Thanx, I'm already using RadAjaxManager, but this was specific thing, because RadAjaxPanel was placed in user control which might or might not be placed on page with ScriptManager.

Thanx anyway, I replaced RadAjaxPanel with UpdatePanel and it works.
Reason why I just posted reply is that you can reproduce this bug and of course this was one of the first items in google when I try to search for workaround, so anyone now can solve this problem;)

I'm having the same problem, formview and everything, however my formview is in a user control, which does not seem to have the OnPreRenderCompleted event.  I tried to add the code in the example to the PreRender event, but this does not seem to work.  Do you have any reccomendations?  Thanks.

Hi Richardsonke,

In cases like yours, where a user control is used, you can try moving the code to UserControl's PreRender event. Similar to the following:

    protected override void OnPreRender(EventArgs e)  
    {  
        Control control = FormView1.FindControl("Panel1");  
        RadAjaxManager1.AjaxSettings.AddAjaxSetting(control, control);  
        base.OnPreRender(e);  
    } 

Please give it a try and let us know about the result.

Yes, I've tried the OnPreRender event of the user control, but I get the same error.  Any ideas?  Thanks.

Hi Richardsonke,

I'm afraid that I'm unable to reproduce the behavior you have described. I have attached a modified version of the page. Please take a look and let me know if I'm missing something obvious.

Sorry, I oversimplified what I was trying to do because I misunderstood where the issue was coming from.  It seems that the problem is that I have a RadAjaxPanel inside of my form view (full disclosure: the RadAjaxPanel is actually inside of a user control that's inside of the formview template).  To reproduce this, you just have to modify your previous solution to change the WebUserControl.ascx file to look like this:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">  
    <asp:FormView runat="server" ID="FormView1" DefaultMode="Edit">  
        <EditItemTemplate> 
            <asp:Panel runat="server" ID="Panel1">  
                <asp:Button runat="server" ID="Button1" OnClick="Button1_Click" /><br /> 
                <telerik:RadAjaxPanel ID="RadAjaxPanel2" runat="server">  
                    text  
                </telerik:RadAjaxPanel> 
            </asp:Panel> 
        </EditItemTemplate> 
    </asp:FormView> 
</telerik:RadAjaxPanel> 
 

You will then receive the following error when clicking the button: 

System.ArgumentException: Script control '' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().\r\nParameter name: scriptControl\r\n at System.Web.UI.ScriptControlManager.RegisterScriptDescriptors(IScriptControl scriptControl)\r\n at System.Web.UI.ScriptManager.RegisterScriptDescriptors(IScriptControl scriptControl)\r\n at Telerik.Web.UI.ProxyScriptControl.Render(HtmlTextWriter writer)\r\n at System.Web.UI.Control.RenderControlInternal(HtmlTextWriter writer, ControlAdapter adapter)\r\n at System.Web.UI.Control.RenderControl(HtmlTextWriter writer, ControlAdapter adapter)\r\n at System.Web.UI.Control.RenderControl(HtmlTextWriter writer)\r\n at System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children)\r\n at System.Web.UI.Control.RenderChildren(HtmlTextWriter writer)\r\n at System.Web.UI.Control.Render(HtmlTextWriter writer)\r\n at System.Web.UI.Control.RenderControlInt

(note: this is the expanded version of the error by handling the ScriptManager1_AsyncPostBackError event).

Any help you can provide would be appreciated.  Thanks.

Hello Richardsonke,

As I stated in my previous message, this behavior is caused by the fact that when controls are moved, the internal registration list  inside ScriptManager  is not refreshed. Therefore in order to workaround this, you should use RadAjaxManager instead of RadAjaxPanel as shown in the previously sent example.

Sincerely yours,
