Hello everyone,

I am having a issue that I can't seem to fix. When I call the following in a render overide:

    
              Dim s_wtr2 As New StringWriter()  
        
                        Dim h_wtr2 As HtmlTextWriter = New HtmlTextWriter(s_wtr2)  
        
                        'Check Type  
        
                        If drpType.SelectedValue = "CC Declined" Then 
        
                            gridPacc.RenderControl(h_wtr2)

I get the following error:

Script control 'gridPacc' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors(). Parameter name: scriptControl

"grdPacc" is a Q1 asp.net ajax telerik grid.

Any other control done the same way does not produce the error. Any help is appreciated.

Hi TadR,

You cannot invoke the RenderControl() method directly in such a way since this will not work for the standard MS GridView as well. Here is a sample code implementation which threw an exception on my machine related to the GridView instance:

    
                    <asp:ScriptManager ID="ScriptManager1" runat="server">  
        
                    </asp:ScriptManager> 
        
                    RadGrid  
        
                    <br /> 
        
                    <telerik:RadGrid ID="radgrdData" runat="server" /> 
        
                    MS GridView  
        
                    <br /> 
        
                    <asp:GridView ID="GridView1" runat="server" /> 
        
                    <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />

    
                protected void Button1_Click(object sender, EventArgs e)  
        
                {  
        
                    DataSet ds = new DataSet();  
        
                    ds.ReadXml(Server.MapPath("~/GridContent.xml"));  
        
                    radgrdData.DataSource = ds.Tables[0];  
        
                    radgrdData.DataBind();  
        
                    GridView1.DataSource = ds.Tables[0];  
        
                    GridView1.DataBind();  
        
                    StringWriter sw = new StringWriter();  
        
                    HtmlTextWriter htw = new HtmlTextWriter(sw);  
        
                    GridView1.RenderControl(htw);  
        
                    Response.Write(sw);  
        
                    sw = new StringWriter();  
        
                    htw = new HtmlTextWriter(sw);  
        
                    radgrdData.RenderControl(htw);  
        
                    Response.Write(sw);  
        
                }

This might be possible for other simple controls like ASP Menu for example but cannot be attained for complex controls like grids, data lists, etc.

Let me know if I am leaving something out.

Hey Guys Is There Any Other Way to Trouble Shoot this.
I Too Have The Same Problem.
Here is My Sample Cide

private void rendergrid(RadGrid _grid)
    {




        using (StringWriter sw = new StringWriter())
        {
            HtmlTextWriter htw = new HtmlTextWriter(sw);

            _grid.RenderControl(htw);
            htw.Flush();
            returnValue = sw.ToString();
        }
    }

The Highlighted One Produced the Error For me Threw The Exception
As it Goes Like This:"Script control 'RadGrid1' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl".

Hi,

set the "RegisterWithScriptManager" property to false.. finally got the solution...

But i am facing a new problem...

1.following are the error message i got

Microsoft JScript runtime error: Sys.InvalidOperationException: Type Telerik.Web.UI.Orientation has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.

2.Microsoft JScript runtime error: Object doesn't support this property or method

finally i got 7 jscript runtime error ....

how to solve this problem....

Thanks

Hello Sabarishbabu,

You can manually remove the scripts with Regex as demonstrated in the attached demo.

Let me know whether this helps.

Hello,
in my case I design an usercontrol and was using with:
var AndamentosCrono1 = (MyControl)Page.LoadControl("~/MyControl.ascx");
and loading into a placeHolder.
The error raised when an old page was trying load with:
<%@ Register Src="MyControl.ascx" TagName="MyControl" TagPrefix="myctl" %>
<uc1:MyControlID="MyControl1" runat="server" />
After removing the register and reference on page is solved by it self.
