Reload Data
As of R3 2016, through the new ReloadData method you can refresh RadPropertyGrid's data engine - reload the set of PropertyDefinitions, reload the list of item properties and recreate the PropertySetViewModel, if PropertySetMode is different from None.
Note that this is different from the Rebind method which simply recreates RadPropertyGrid's contents according to the bound data.
Example 1: Call RadPropertyGrid's ReloadData method
this.radPropertyGrid.ReloadData();
Me.radPropertyGrid.ReloadData()
Calling the ReloadData method will also clear RadPropertyGrid's SelectedPropertyDefinition.
