WebDataGrid with MasterPage

Thierry Leroux-Demers posted over 13 years ago

I am following the example from https://www.infragistics.com/community/product_platforms/aspnet/w/aspnet-wiki/49/data-binding-the-webdatagrid-to-common-data-sources to bind to an ObjectDataSource. As it stands, it is working and I am also successful activating the cell editing and row adding behaviors. However, as soon as I use a MasterPage and put this within a Content, I receive "Deserialization failure: Invalid response" warnings on all add or edit actions. I have also added code-behind to assign the datasource dynamically. Can you help? Here is my code:

MASTER PAGE:

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>
<%@ Register assembly="Infragistics35.Web.v10.3, Version=10.3.20103.1013, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" namespace="Infragistics.Web.UI.NavigationControls" tagprefix="ig" %>

Oups... sorry for the long snippet I accidentally left in the text.

MORE IMPORTANTLY... I noticed I had not provided the MasterPage.Master.cs contents. When I went to copy it, I realized I had a Page_Init piece of code to change the master page ID to "_master" (rather than the default "ctl00"). After I removed that, the warnings disappeared.
