ControlPanelItem without GridViewSelectColumn

[Heiko]

If followed the Telerik ControlPanelItem "Column chooser" example. It works perfect, though now I have two entries for the GridViewSelectColumn and GridViewToggleRowDetailsColumn which I don't want to display. Is there a way to remove those from the columns list?

Hello Neils,

A possible way to remove the GridViewSelectColumn and GridViewToggleRowDetailsColumn columns from the displayed list in the "Column Chooser" dropdown button is to use a convert. For example you can return another collection that excludes the mentioned columns like so:

public class ColumnChooserConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            ObservableCollection<GridViewColumn> otherColumns = new ObservableCollection<GridViewColumn>();
            if (value != null)
            {
                var columns = value as Telerik.Windows.Controls.GridViewColumnCollection;

                foreach (var column in columns)
                {
                    if (!column.GetType().Name.Equals("GridViewToggleRowDetailsColumn") && !column.GetType().Name.Equals("GridViewSelectColumn"))
                    {
                        otherColumns.Add(column);
                    }
                }

            }

            return otherColumns;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            // TODO: Implement this method
            throw new NotImplementedException();
        }
    }

I hope this helps.
