For example when setting the following code in App.xaml resources
<Style TargetType="telerikInput:RadComboBox"> <Setter Property="DropDownBorderColor" Value="Red"/> <Setter Property="VerticalOptions" Value="Center"/> <Setter Property="SearchMode" Value="Contains"/> <Setter Property="Placeholder" Value="rwfrfre"/> <Setter Property="PlaceholderColor" Value="Yellow"/> <Setter Property="DisplayMemberPath" Value="Population"/> <Setter Property="SearchTextPath" Value="Name"/> </Style>
null ref exception is thrown for DisplayMemberPath and SearchTextPath.
When setting the style inside the page where the control is defined, it works as expected.
