Grid with Hierarchy and sorting

[AdamL]

My question is two parts:

1.  I have a Hierarchy grid that is not keeping state.  When I expand nodes and then sort the top level grid, the grid retruns to the all-collapsed state.  Is there a way to maintain the expand / collapse state during the sort callback?

2.  I also need a way to collapse all / expand all from a button press.  This needs to work in conjunction with #1.  The button for the action can be in the grid action bar or a separate button outside the grid.

Thanks in advance.

Hi Lindsaad,

1. Here is code library submission which explains how to retain the expanded state in hierarchical Grid on rebind.

2. I have submitted a code library on adding ExpandAll/CollapseAll option in the grid header for a hierarchical grid. Go through it and see whether it meet you requirements.
