PROJECT DESCRIPTION
This is an alternative way to handle [ENTER] key to perform insert/update operation inside a RadGrid FormTemplate (EditFormType="Template") within a Content Page (Master Page template). For unknown reason (probably the FormTemplate with customized insert/update and cancel button), I was unable to handle the [ENTER] key event so this is a possible solution:

                     <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">         
                    <script type="text/javascript" language="javascript">         
                        function onKeyPress(sender, eventArgs) {         
                            // 13 is the keycode for enter key         
                            if (eventArgs.get_keyCode() == 13) {         
                                // LblUpdateButtonId it's an hidden label that contain the id of my custom insert/update button         
                                var temp = document.getElementById("<%=LblUpdateButtonId.ClientID %>");         
                                var button_id = temp.innerHTML.replace(/_/g, "$");         
                                // perform postback         
                                WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(button_id, "", true, "", "", false, true));         
                                // inhibit event bubbling         
                                eventArgs.set_cancel(true);         
                            }         
                        }         
                </script>         
                </telerik:RadCodeBlock>         

The custom insert/update asp:button calls a sub on OnLoad event (OnLoad="SetUpdateButtonId") to store his client id in the hidden label because I was unable to retrieve it in a different way:

                    Protected Sub SetUpdateButtonId(ByVal sender As Object, ByVal e As System.EventArgs)         
                  LblUpdateButtonId.Text = CType(sender, Button).ClientID         
            End Sub
