Expand rows in hierarchical grid

Hi,

I have a hierarchical grid with about 4 levels. When the form opens up for the firs time, I would like only the first level to be expanded and all other levels to be collapsed. Is there a way to achieve this. The only code I have seen pertaining to this is " this.grid.Rows.ExpandAll() ", but this expands all the rows. I only want only one level to be expanded.

Thanks,

Deepak

  Hi,

  The grid has two API providing Row objects: grid.Rows and grid.Nodes. The first one represents only visible rows. The second - rows (visible and invisible) on  the top level of the grid. So if you need to expand only the first level, use the following code:

   

  foreach (Row row in grid.Nodes)
  {
      row.Expanded = true;
  }

  Best regards,
