Error with RadGrid inside FormView

[Henrique Duarte]

Hi,

I'm getting this error after FormView Updated or Inserted :
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Script control 'gridEnderecos' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

Here is my code:

Hello Henrique,

Have you tried wrapping the FormView into an ASP:Panel and add Panel -> Panel AJAX setting instead? Here are the expected settings for your convenience:

    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="bSalvar">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="Panel1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="Panel1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="Panel1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>

I hope this helps!

Hi Konstantin,

It didn't work.
After Inserted or Updated a record, I need to redirect to same page to avoid this issue.

Another suggestion?

Henrique

Hi Henrique,

I've checked our records and it seems we've got a few other reports with the same error and RadGrid including one when the Grid has been placed in a FormView. It appeared however the issue was caused by improper AJAX settings but in your case those look correct. I assume there is something else within the implementation so we will need to look into your code and investigate the problem locally instead of shooting in the dark.

Can you please isolate the problem as much as possible (removing controls/code which do not affect the problem) and send a runnable application through a regular support ticket? You can use dummy data binding the Grid/FormView since I bet the data has nothing with the actual problem.

We will gladly debug the error and get back to you with our findings/resolution. Thank you for the understanding and cooperation and looking forward to hearing from you.

Hello Henrique,

I have verified your project and I notice that this exception was caused by this ajax setting:

            <telerik:AjaxSetting AjaxControlID="FormView1$RadGrid1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="FormView1$RadGrid1" />
                </UpdatedControls>
            </telerik:AjaxSetting>

Please remove this to avoid the problem!

Kind regards,
Vlad

Hi Vlad,

There is no other to do that?
My FormView is huge and I need to insert items in RadGrid before saving the data.

Henrique

Hello Henrique,

Here is an example how to add the same setting programatically:

        protected void Page_PreRenderComplete(object sender, EventArgs e)
        {
            RadGrid RadGrid1 = (RadGrid)FormView1.FindControl("RadGrid1");
            RadAjaxManager1.AjaxSettings.AddAjaxSetting(RadGrid1, RadGrid1);
        }

I had the same problem with a radGrid inside an asp:FormView. The radGrid uses a userControl as its EditForm (irrelevant?). I was getting:

      script control '' is not a registered script control. script controls must be registered using registerscriptcontrol() before calling registerscriptdescriptors().

My code (copied from http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/usercontroleditform/defaultcs.aspx ) included this:

        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadGrid1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>

When removed, my error went away and my page worked correctly.
