Thank you for the RadGridViewSettings.cs file.  Every thing work #1 except when I sort on a GridViewDynamicHyperlinkColumn and save it.

See error message in attachement.

Error at this line (setting.PropertyName = ((GridViewDataColumn)d.Column).GetDataMemberName();) :

foreach (ColumnSortDescriptor d in grid.SortDescriptors.OfType<ColumnSortDescriptor>())
{
    SortSetting setting = new SortSetting();
    setting.PropertyName = ((GridViewDataColumn)d.Column).GetDataMemberName();
    setting.SortDirection = d.SortDirection;
    Settings.SortSettings.Add(setting);
}

Any idea ?

{System.InvalidCastException: Impossible d'effectuer un cast de l'objet de type 'Telerik.Windows.Controls.GridViewDynamicHyperlinkColumn' en type 'Telerik.Windows.Controls.GridViewDataColumn'.
   à mesespacesclos.RadGridViewSettings.SaveState()
   à mesespacesclos.RadGridViewSettings.grid_Unloaded(Object sender, RoutedEventArgs e)
   à MS.Internal.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
   à MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)}

Hello Louis Bouchard,

 GridViewDynamicHyperlinkColumn descends from GridViewBoundColumnBase, not GridViewDataColumn.

Kind regards,
