The fix will be available with lib version 2016.1.328

Currently, if you change the value of a property in the object bound to the property grid control, the control's UI won't reflect this change.

RadPropertyGrid exposes PropertySetsValidationFunc property that validates the new value of a property. However, it is executed after the property is set. PropertyGrid should validate them before the setter is invoked.

I understand from http://docs.telerik.com/devtools/wpf/controls/radpropertygrid/features/validation, that there are essentially two methods to implement data validation in a RadPropertyGrid.  Note that I would like to use the "property set" feature of RadPropertyGrid whereby I can display/edit properties from multiple items simultaneously (http://docs.telerik.com/devtools/wpf/controls/radpropertygrid/features/defining-propertysets).

I was only able to get the second validation technique (data annotations) to work when using property sets.  Should the first technique (IDataErrorInfo) work with the property sets feature?  Towards the end of the discussion here http://www.telerik.com/forums/validation-bfd78b274562, this topic is touched on, but it is not clear if it was ever resolved.

If it is not possible to use the IDataErrorInfo technique with property sets, I suggest the documentation at http://docs.telerik.com/devtools/wpf/controls/radpropertygrid/features/validation be updated to reflect this fact.  Separately, is there a target date for when this feature may be added?

If it is possible to use the IDataErrorInfo technique with property sets, would someone kindly post a sample solution?

Expose an event  corresponding to AutogeneratingPropertyDefinition so that the user can customize the property definitions.

 Provide a straight-forward option for customers to set their custom tooltip. An example showing how to achieve this now is available at https://github.com/telerik/xaml-sdk/tree/master/PropertyGrid/CustomHyperlinkToolTip

The problem should be resolved with R2 2016. 

The fix is available with lib version 2015.2.907.

Fixed with LIB version 2015.2.817.

Research the opportunity to add support for TypeConverter on class.

Available in the 2017 R1 Release (2017.1.117).

It should be a themable editor which allows users to select a file or a directory from the file system using OpenFileDialog, FolderBrowserDialog or directly to type the full path to the file.
