DataFormatString is not respected when exporting RadGridView to .xlsx file and a GridViewDataColumn is bound to a nested property.

Available in LIB version: 2017.2.605

Available in the 2017 R1 release (2017.1.117).

The issue is reproduced only when the items in the source collection have properties with duplicated values and they are sorted before the selection is processed. If the property values are unique or the SelectionMode is set to Multiple, the selection works as expected both with sorted and unsorted data. The workaround is to use either Multiple SelectionMode, or Cell/Mixed SelectionUnit.

For the time being, an appropriate converter should be used for the bindings.

Add a TextAlignment property to the GridView's AggregateFunctions to set the alignment of the resulting text. 
Apply to both Caption and FormattedValue simultaneously. 
This way we won't have to make custom ItemTemplates for the AggregateResultsList in each footer, when using AggregateFunctions out-of-the-box.

As a temporary workaround, the following custom keyboard command provider can be used:

	public class CustomKeyboardCommandProvider : DefaultKeyboardCommandProvider
	{
		private GridViewDataControl parentGrid;

		public CustomKeyboardCommandProvider(GridViewDataControl grid)
		 : base(grid)
		{
			this.parentGrid = grid;
		}

		public override IEnumerable<ICommand> ProvideCommandsForKey(Key key)
		{
			List<ICommand> commandsToExecute = base.ProvideCommandsForKey(key).ToList();

			if (key == Key.Enter)
			{
				commandsToExecute.Clear();
				commandsToExecute.Add(RadGridViewCommands.CommitEdit);
				commandsToExecute.Add(RadGridViewCommands.BeginEdit);
				commandsToExecute.Add(RadGridViewCommands.MoveDown);
			}

			return commandsToExecute;
		}
	}

In an application, I bind a DataTable with many rows to a RadGridView. As soon as, the datatable is binded, I see the memory needed by the application growing. The problem is that the binding is done each time the content of the DataTable is changing. It seems that the memory is never cleared and keep growing until a MemoryException is thrown. This does not appear with a WPF standard GridView. Do you know why ?
