RadGrid for ASP.NET NestedView How To Stop multiple views?

[Ed Paay]

I have successfully created a grid in asp.net with a nested view.  Since I am new to radgrid I am wondering what is the best way to cause a currently displayed nested view to close before a new one is opened when the user clicks on a different parent row drop down button?  I only want one nested view to be open at the time.

Thanks ed.

Hi Ed Paay,

Add the following code snippet in ItemCommand in order to allow single row expand at a time for each level in the grid hierarchy.

C#:

    protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == RadGrid.ExpandCollapseCommandName)
        {
            foreach (GridItem item in e.Item.OwnerTableView.Items)
            {
                if (item.Expanded && item != e.Item)
                {
                    item.Expanded = false;
                }
            }
        }
    }

Is there a better way to do this now like assigning a property or something so that this occurs with out a postback?
