When the Expression_Dark theme is applied to the RadPropertyGrid, selecting an item is hard to read, as the item's foreground is white and the selection state is in a similar color.

To work this around, use the following Style:

<Style TargetType="telerik:PropertyGridField">
    <Style.Triggers>
        <Trigger Property="IsSelected" Value="True">
            <Setter Property="Foreground" Value="Black"/>
        </Trigger>
    </Style.Triggers>
</Style>

 Add selected inactive state for PropertyGrid Field.

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)

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.
