Add selected inactive state for PropertyGrid Field.

Add an event that is raised when the editor's value gets updated and just before the value is updated back to the associated data item when PropertySetMode is Union or Intersection.

Currently, you can use the PropertySetsValidationFunction to intercept this moment, but the function is not invoked only for the currently edited property, but for all other properties in the PropertyGrid and you cannot indicate which one triggered the change.

Improve loading performance when IsGrouped="True" and AutoExpandGroups="True".

Currently the AutomationID of the PropertyGridField is set to "{0}_FieldEditor", where {0} is the DisplayName of the property definition. We can introduce an option to prevent this.

An non edit mode is enabled in the control when the EditMode is set to Single. In this case, only one field can enter edit mode and the rest are read only. 

Currently, there is no API that allows you to customize the content (that shows the property value) of the read only fields.

Add an API that allows you to customize the read only content. Similar to the EditorTemplate of the PropertyDefinition.

 

By the time being, a custom DataTemplate can be applied only for the EditorTemplate. When the EditMode is Single, a plain TextBlock is used for a readonly PropertyDefinition. With the Default EditMode, if the EditorTemplate is set, it will be displayed, but the user needs to stick to the default behavior provided by the ReadOnlyEditorState property (grayed out and disabled element for its Disabled value, and enabled interaction for the ReadOnly one). Provide an option to directly set a ReadOnlyTemplate for both EditModes.

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.

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

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.

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