Version=10.2.20102.1011

The following parameters are set inside the control's init event

var grid = sender as WebHierarchicalDataGrid;

grid.Width = new Unit("100%");
grid.IsSelfReference = true;
grid.MaxDataBindDepth = 2;
grid.AutoGenerateBands = false;
var gs = grid.GroupingSettings;
gs.ShowBandInGroupByArea = false;

the grid is binded to a dynamic selfreferenced WebHierarchicalDataSource

and the DataKeyFields of the grid contains 2 keys.

It all works well expand and collapse well from the browser, however it is always started collapse no matter what I do, I've try setting these two properties of the grid to -1 in many places as well as in the asp.net form as I sent before, with the same results.

I will, but first I would like to solve a preceding problem that might solve this one as well, it is described in this post I send:

which has not been replied for some reason.

Ok, thank you for your help with the other thread, I'm still having problems with expanding all rows, I can produce a scenario with static columns to work, but I can't produce it to work with auto created columns and bands using dynamic WebHierarchicalDataSource.

Can you provide a working example ?
