The Exception is thrown as if the RenderMode is not set to Flat. If the GroupStyleSelector is defined before the RenderMode, the issue is not reproduced.

 SelectedPropertyDefinitions are not cleared when RadPropertyGrid.Item being changed.

Currently the only option is to call the Expand/Collapse groups API, which takes noticable time to execute.

Currently, when RenderMode Flat is enabled, RadPropertyGridd uses a custom navigation behavior. The default framework navigation is available only when RenderMode is Hierarchical.

Hello,
my question is about RadPropertyGrid.
The case if following. I use objects implementing ICustomTypeDescriptor, call it ClassTypeDescriptor, as items source for property grid and properties are derived from PropertyDescriptor class. It is important to have these objects grouped and sorted. That's why I pass System.ComponentModel.DataAnnotations.DisplayAttribute with GroupName and Order values set to the constructor of PropertyDescriptor. If I bind Item property of property grid direct to ClassTypeDescriptor, everything works like a charm, properties get grouped and sorted. But if I bind Item property to the List or any other collection of ClassTypeDescriptor, independently from the count of elements in it, grouping is getting lost and sorting is not applied also. I attach the demo solution to this report and hope for the quick answer.

P.S.: I've tried the same case but with "normal" object with properties. And grouping and sorting work even if I bind a collection to Item property of PropertyGrid

Thank you in advance

Add an additional EditorAttribute's constructor which takes the type's name as a string.

Available in the 2017 R1 Release (2017.1.117).

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

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.
