Context Menu - Javascript GetDataKeyName of Parent

[Josh]

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
