A memory leak occurs when RadPropertyGrid instaces are loaded/unloaded multiple times. 

The issue manifests even more if the PropertyGrid contains fields for editing DateType types. 

See if we can improve the TryGetValueByReflection method when using dynamic objects.

The reason for the flickering is the group needs to be recreated so that its content to be updated.

BindingMode is OneWay when there is editor template and PropertySetMode is None

Resolved with LIB version 2014.1.407.

SearchTextBox is clipped, when SortAndGroupButtonsVisibility property of RadPropertyGrid is set to Collapsed, in Windows8Touch theme

Fixed with LIB version 2015.2.817.

The fix is available with lib version 2015.2.907.

The problem should be resolved with R2 2016. 

 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

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?

The fix will be available with lib version 2016.1.328

Expose a boolean property that states whether to save the expanded state of the group and property definitions and the filter descriptor.
