expandTreeLevel( rrn )

This method expands the tree level at the specified row, which is considered the "parent" row. All "child" rows belonging to that parent row will be expanded (displayed).


  • rrn -  relative record number of the row for which to expand the tree level, where 1 is the first row, 2 is the second row, etc. If 0 is specified, then all rows will be expanded.

*Row n refers to the original row number as written by the server-side program, and does not change when filters or sorts are applied.

Please see here for a grid tree example.


// expand the tree level for first row getObj("Grid1").grid.expandTreeLevel(1);
