[Devang]

Hello Friends,

   I am getting same old "Script control '' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors(). Parameter name: scriptControl " as soon as I write following code to enable ajax for the radgrid. 

<telerik:RadAjaxManagerProxy ID="AjaxManagerProxy1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="rgUploadedDocs">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rgUploadedDocs" LoadingPanelID="RadAjaxLoadingPanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManagerProxy>

 

I am not doing anything special here. All I have is main aspx page with master page and few user controls in it. One of the user controls is already having RadAjaxManager so I am using RajAjaxManagerProxy in my user control. Following is my full aspx page code. I would appreciate if someone can help me on this. 

 

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="UploadDocument.ascx.cs" Inherits="UserControls_UploadDocument" %>
<%@ Register Src="~/UserControls/FormField.ascx" TagName="FormField" TagPrefix="uc" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>


<span id="uploadMessage" runat="server"  visible="true" class="formLabelAuto">The documents shown below are uploaded from this page only. You have to navigate to the specific page to view the documents on that page.</span>

        var selectText = selectElem.options[selectElem.selectedIndex].text;

        if (selectText.toUpperCase() == 'OTHER') {
            document.getElementById('<%= txtDescription.ClientID %>').removeAttribute('disabled');
        }
        else {

        }

    }
