    I have a ColorPircker on a ToolBar bound  to a string property.  Everything is working as expected, but I noticed an uncaught exception being thrown in one of the Telerik dlls. Here it is:

    A first chance exception of type 'System.NullReferenceException' occurred in Telerik.Windows.Controls

    I've verified that the string is never null, so I am assuming this is coming from inside the Controls dll.  Has anyone else noticed this before?

    We are also facing same issue with ColorPicker. We are trying to use this in PropertyGridDefinition. Exception get raised when I click on SplitButton of ColorPicker.

    <DataTemplate x:Key="backgroundTemplate">
                    <telerik:RadColorPicker SelectedColor="{Binding NormalHeaderBackground, Converter={StaticResource colorToBrush}, Mode=TwoWay}"  NoColorVisibility="Visible" HeaderPalette="Office" MainPalette="Grayscale" StandardPalette="Standard" />

    Hello Kim,

    Could you please elaborate a bit more on your scenario - what is the type of exception, what steps do you perform, etc ? Do you follow the approach from this demo - PropertyGrid First Look ? Is it possible for you to open a new support thread with an isolated project that we can investigate ? Thank you in advance for your cooperation.
