Error "Sys.WebForms.PageRequestManagerParserErrorException"

[Venkatesh]

HI,
When i add more than 6 records in the grid, i am getting the below error:

"Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near ' Thank you for using'. "

I am not using the trial version and below is the aspx code for the radajax and radgrid added. This error is shown in the scriptresource.axd file.

<div class="Table">
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                <AjaxSettings>
                    <telerik:AjaxSetting AjaxControlID="radgrid1">
                        <UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="radgrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                            <telerik:AjaxUpdatedControl ControlID="hdnRowsCount" LoadingPanelID="RadAjaxLoadingPanel1" />
                        </UpdatedControls>
                    </telerik:AjaxSetting>
                </AjaxSettings>
            </telerik:RadAjaxManager>
            <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Height="75px"
                Width="75px" Transparency="25">
                <img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>'
                    style="border: 0;" /></telerik:RadAjaxLoadingPanel>
            <asp:HiddenField ID="hdnRowsCount" runat="server" Value="0" />

<telerik:RadGrid ID="radgrid1" runat="server" ShowStatusBar="True" ShowFooter="True"
                OnItemCommand="radgrid1_ItemCommand" OnDeleteCommand="radgrid1_DeleteCommand"
                OnInsertCommand="radgrid1_InsertCommand" OnUpdateCommand="radgrid1_UpdateCommand"
                OnNeedDataSource="radgrid1_NeedDataSource" OnItemDataBound="radgrid1_ItemDataBound"
                CellSpacing="0" GridLines="None">
                <MasterTableView DataKeyNames="ProductNumber" AutoGenerateColumns="false" EditMode="InPlace"
                    CommandItemDisplay="TopAndBottom" CommandItemSettings-AddNewRecordText="Add New Order">
                    <Columns>

How to fix this?

Thanks

Hi Venkatesh,

I tried to reproduce the described issue but to no avail. I am sending you a simple example based on your code please check it out and let me know what differs in your case. Also it will be helpful if you post the aspx page markup with the related code behind.

Looking forward for your reply.

Kind regards,
Radoslav
