Hello kyle,

Here is an example:

    
            <%@ Page Language="C#" %> 
        
            <%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <script runat="server"> 
        
                protected void RadGrid1_UpdateCommand(object source, GridCommandEventArgs e) 
        
                { 
        
                    UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID); 
        
                    ListDictionary keyValues = new ListDictionary(); 
        
                    ListDictionary newnewValues = new ListDictionary(); 
        
                    ListDictionary oldValues = new ListDictionary(); 
        
                    keyValues.Add("ProductID", ((GridEditFormItem)e.Item).ParentItem.GetDataKeyValue("ProductID")); 
        
                    oldValues.Add("ProductName", ((GridEditFormItem)e.Item).ParentItem["ProductName"].Text); 
        
                    newValues.Add("ProductName", ((TextBox)userControl.FindControl("TextBox1")).Text); 
        
                    LinqDataSource1.Update(keyValues, newValues, oldValues); 
        
                } 
        
            </script> 
        
            <html xmlns="http://www.w3.org/1999/xhtml"> 
        
            <head runat="server"> 
        
                <title>Untitled Page</title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                <div> 
        
                    <asp:ScriptManager ID="ScriptManager1" runat="server" /> 
        
                    <telerik:RadGrid ID="RadGrid1" DataSourceID="LinqDataSource1" AutoGenerateEditColumn="true" 
        
                        runat="server" OnUpdateCommand="RadGrid1_UpdateCommand"> 
        
                        <MasterTableView DataKeyNames="ProductID" AllowAutomaticUpdates="true"> 
        
                            <EditFormSettings EditFormType="WebUserControl" UserControlName="WebUserControl.ascx"> 
        
                            </EditFormSettings> 
        
                        </MasterTableView> 
        
                    </telerik:RadGrid> 
        
                </div> 
        
                <asp:LinqDataSource ID="LinqDataSource1" runat="server" ContextTypeName="DataClassesDataContext" 
        
                    EnableUpdate="True" TableName="Products"> 
        
                </asp:LinqDataSource> 
        
                </form> 
        
            </body> 
        
            </html>

and the UserControl code:

    
            <%@ Control Language="C#" ClassName="WebUserControl" %> 
        
            ProductName: <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("ProductName") %>'></asp:TextBox> 
        
            <asp:LinkButton ID="LinkButton1" CommandName="Update" runat="server">Update</asp:LinkButton> 
        
            <asp:LinkButton ID="LinkButton2" CommandName="Cancel" runat="server">Cancel</asp:LinkButton>
