Nested View Template Relationships

[Michael]

Hi,

I have a three tier datagrid Hierarchy which basically consists of a Radgrid, in the Radgrid i have specified a master table and a detail table.  Within the detail table i have also specified a nested view template which holds another radgrid.  The set up works fine as everything expands as it should.

However, while selecting an item in the 3rd level of the hierarchy i would like to obtain a reference to the item expanded in the first level.
at present i am trying to perform this operation like so 

e.Item.OwnerTableView.ParentItem.GetDataKeyValue("EnquiryNo");

 The event isn't important, but e is of type GridSortCommandEventArgs.

The problem with this is that ParentItem is null.

This technique has worked in the same project when trying to get a handle from the detail table to the master table which leaves me to believe that a relationship must be set up between the nested view template and the detail table.

Any help will be greatly appreciated thank you

Hello Michael,

Try the following code snippet to get the DataKeyValue of item in MasterTable(first level).

C#:

protected void RadGrid2_SortCommand(object source, GridSortCommandEventArgs e)
   {
       RadGrid RadGrid2 = (RadGrid)source; // grid inside NestedViewTemplate
       GridNestedViewItem item = (GridNestedViewItem)RadGrid2.NamingContainer;
       item.ParentItem.OwnerTableView.ParentItem.GetDataKeyValue("EnquiryNo");
   }

Thanks,
Princy.
