Row collapses upon edit

[Justin Lee]

I have a hierarchical RadGrid that is editable.  If you edit a row that is expanded, the row collapses once in edit mode.  Once its in edit mode, you can expand it again and it remains in edit mode. This can be seen in the Telerik demos (http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/threelevel/defaultcs.aspx) so I'm guessing this is the way it was designed, and is not a bug.  But is there a way I can prevent a row from collapsing when it enters edit mode?

Thanks,
Justin

Helo Justin,

You can customize the behaviour by saving the editform index in global variable and setting the Expanded property back to True (if it was expanded before). Please feel free to change  the logic based on your requirement.

code:

public int check = -1;
protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.EditCommandName)
    {
        if (e.Item.Expanded)
        {
            e.Item.Expanded = true;
            check = e.Item.ItemIndex;
        }
    }
}
protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    if (check > 0)
    {
        RadGrid1.MasterTableView.Items[check].Expanded = true;
    }
}
