I am running this example

http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/xmldatasource/defaultcs.aspx

but getting this error "Unable to cast object of type 'Telerik.Web.UI.GridDataItem' to type 'Telerik.Web.UI.GridEditFormItem'
" on bold line

protected void RadGrid1_UpdateCommand(object source, GridCommandEventArgs e)

{

GridEditFormItem gridEditFormItem = (GridEditFormItem)e.Item;

Hashtable ht = new Hashtable();

gridEditFormItem.ExtractValues(ht);

aspx code is like this:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="EditAll.aspx.cs" Inherits="EditAll" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<br />

<asp:XmlDataSource ID="XmlDataSource1" runat="server" DataFile="~/App_Data/XML/Customer.xml">

</asp:XmlDataSource>

</form>

</body>

</html>

Is there way to cast directly, to resolve this error?

Thanks
