Hello all. I am currently having a problem getting the DataKeyValue from
my DetailTables data. The MasterTableView works fine, however, the
same logic does not work with DetailTables. I have searched the forum
and cannot fine any reference to this problem before. Anyone have any
clues? Code posted below. Thanks in advance.

    
            <telerik:RadGrid ID="RadGrid1" DataSourceID="SqlDataSource1" runat="server" Width="97%" AutoGenerateColumns="False"  AllowSorting="True"  ShowStatusBar="true" Skin="Office2007">

Hi Joshua,

In your code, I find that you are using the wrong ClientDataKeyName for teh DetailTable. Since you have set the ClientDataKeyNames for the detailtable as DataID, youhave to pass the same field name in the code to access the key value on client:
js:

    
            function RowClicked(sender, args)  
        
               {   
        
                    if(args.get_tableView().get_name() == "EventTable")   
        
                       alert(args.getDataKeyValue("EventID"));   
        
                    if (args.get_tableView().get_name() == "DataTable")   
        
                       alert(args.getDataKeyValue("DataID"));   
        
                }

Thanks
