I have 3 grids, one inside the other as a tree. As I get a value from the first grid, being inside the 3rd grid, I have the code:
GridDataItem parentItem = ((source as RadGrid).NamingContainer as GridNestedViewItem).ParentItem as GridDataItem;
With this code I can get the value of grid 2, being within grid 3, but I want to get the value of the 1st grid. How should I do it?
