Hello all. I am trying to get a datakeyname from the parent
of a child table when the Context Menu is displayed. I am
having a difficult time trying to figure this out. Any ideas?
Thanks.

    
            // Abbreviated function for ease of reading  
        
            function ShowContext(sender,args){  
        
            var menu = $find("GridContextMenu");  
        
            var selectedindex = args.get_itemIndexHierarchical();  
        
            //Not sure about below  
        
            var parentindex = sender.get_parentView().getDataKeyNames("EventId");  
        
            menu.show(args.get_domEvent());  
        
            }

Hi Josh,

Give a try with the following approach and see whether it helps.

ASPX:

    
                    <telerik:RadGrid ID="RadGrid2" runat="server" ShowFooter="true" AllowPaging="True" PageSize="7"   > 
        
                            <MasterTableView CommandItemDisplay="Top"  
        
               ClientDataKeyNames="ProductID" > 
        
                                <Columns> 
        
                                  ... 
        
                                </Columns> 
        
                                <DetailTables> 
        
                                    ... 
        
                                </DetailTables> 
        
                            </MasterTableView> 
        
                            <ClientSettings> 
        
                                <ClientEvents OnRowContextMenu="ShowContext" OnRowCreated="OnRowCreated" /> 
        
                            </ClientSettings> 
        
                        </telerik:RadGrid>

JS:

    
            <script type="text/javascript"> 
        
             function ShowContext(sender, eventArgs) 
        
             { 
        
              var selectedindex = eventArgs.get_itemIndexHierarchical();   
        
              var table = eventArgs.get_tableView();  
        
              var ParentRow=table.get_parentRow(); 
        
              if(ParentRow!=null) 
        
              { 
        
               var masterTable = $find("<%= RadGrid2.ClientID %>").get_masterTableView(); 
        
               var currentrow = masterTable.get_dataItems()[ParentRow.sectionRowIndex]; 
        
               alert(currentrow.getDataKeyValue("ProductID")) 
        
              } 
        
            </script>

Thanks
