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".

When a PropertyDefinition with binding to an attached property is added to the PropertyDefinitions collection, the created editor is not bound correctly. 

Currently, the control allows you to search only for fields that have been expanded already. If a parent field was never expanded, the search won't look for its children.

Allow searching in not expanded fields.

Possibility to edit only the SelectedPropertyDefinition (like in Visual Studio)

 

The following exception is thrown when changing the value of specific properties.
InvalidCastException: 'Object must implement IConvertible.'

This happens if the bound property is of a base type and the provided value is of a type that inherits the base type. For example, if you bind to a property of type Brush and you assign a value of type SolidColorBrush.

When a RadPropertyGrid instance is placed inside a RadBusyIndicator, the StyleManager cannot apply the styles correctly and it causes an InvalidOperationException at runtime.

Workaround: Use the NoXaml version of the assemblies with the needed themes.

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.

Behind the scene we need to update any changes made in the property grid, in a SQL Server database, too. With our current implementation we fire a database request if a property is edited in the property grid. This is fine if only one entity has been selected. If more than one entity has been selected (ProperytSetMode “Intersection”) a database request is fired for each entity if a property is edited. This is not very performant for us.
We need an event like “EditEnded” to figure out when the PropertySetViewModel has updated all ViewModels. Then we are able to updated the necessary changes in the database in a single call. 

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.

 

Expose API to control window's location when using Editor attribute with the EditorStyle.Modal

 SelectedPropertyDefinitions are not cleared when RadPropertyGrid.Item being changed.

 

When the PropertyDefinition of the AutoGeneratingPropertyDefinitionEventArgs is set for a nested property definition, it is not respected. 

Nested properties are not loaded when the ComponenetType does not match the DeclarationType. The same setup is correctly presented when using the UI for WinForms' PropertyGrid.
