Using ExpandCollapseCommandName from Parent Grid

[Tim]

I have a Hierarchical DataGrid that is created in a class then displayed dynamically to the form. I am unable to get the  ExpandCollapseCommandName to work on postback in the ItemCommand Event below.

private void ActiveBatchesRadGrid_ItemCommand(object source, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.InitInsertCommandName)
    {
        GridTableView _gridTableView = (GridTableView)e.Item.OwnerTableView;
    }
    if (e.CommandName == RadGrid.ExportToExcelCommandName)
    {
        GridTableView _gridTableView = (GridTableView) e.Item.OwnerTableView;
        _gridTableView.GetColumn("PolicyEditRecord").Visible = false;
        _gridTableView.GetColumn("PolicyDeleteRecord").Visible = false;
        this.__activeBatchesRadGrid.MasterTableView.HierarchyDefaultExpanded = true;
    }
    if (e.CommandName == RadGrid.ExpandCollapseCommandName)
    {
        e.Item.Selected = !e.Item.Expanded;
    }
}

What I would like to do is to GetDataKeyValue() of the parent row when a parent row is expanded

I found the problem. HierarchyLoadMode = GridChildLoadMode.Client should have been set to HierarchyLoadMode = GridChildLoadMode.ServerBind
