Hi,

I have used webdatagrid 13.1 version and locally installed the infragistics. And i have written a aspx page with the below code to enable the cell editing option by clicking mouse with single or double. Its working find for me. But the same code has been deployed where cell clicking is not possible in the grid as part of edit\Update the record. 

asp:ScriptManager ID="ScriptManager1" runat="server">
