Hi,

We are using Infragistcs 2012.1. When we open the column chooser without any columns it is throwing the error (which was fine earlier version)

Here is the scenario. Load the ultrawingrid with datasource then Exclude all the columns form columnchooser as below

 foreach (UltraGridColumn col in this.ultraGrid.DisplayLayout.Bands[0].Columns)
                {
                    col.ExcludeFromColumnChooser = ExcludeFromColumnChooser.True;
                }

Now open column chooser, exception is getting thrown and applcaition gets crash. Please suggest on this.
