Window Custon Theme

[Mikhailo Shuturma]

I created library with my custom theme for RadWindow, but after applying (using StyleManager) and click on header Close button application chashes.

I use this code for close button:

<telerik:RadButton x:Name="PART_CloseButton" Command="telerik:WindowCommands.Close" Style="{StaticResource WindowButtonStyle}">
                                        <Path Fill="{StaticResource WindowButtonIconFill}" Stroke="{StaticResource WindowButtonIconStroke}" Width="14" Height="14" Data="M1.5,3.5 L2.5,2.5 4.5,2.5 6.5,4.5 8.5,2.5 10.5,2.5 11.5,3.5 8.5,6.5 8.5,7.5 11.5,10.5 10.5,11.5 8.5,11.5 6.5,9.5 4.5,11.5 2.5,11.5 1.5,10.5 4.5,7.5 4.5,6.5 z" />
                                    </telerik:RadButton>

Also is use alternate of Command="telerik:WindowCommands.Close":
 
<Button.Command>
    <RoutedUICommand
    Text="Close" />
 </Button.Command>
than button not work.

Help me to resolve this problem.

Thanks

Hi Mikhailo,

 The button doesn't work when you use Command="telerik:WindowCommands.Close"  or <Button.Command>
    <RoutedUICommand
    Text="Close" />
 </Button.Command>.
If the second one is the case - it cannot work, because we are not listening for such a command. We are listening for the telerik:WindowCommands.Close command.

If both don't, please provide us with a sample project that reproduces the issue. This will help us investigate what the problem is.

Kind regards,

When I use "telerik:WindowCommands.Close" after click on close button ("X") my application crashes. My sample projects theme file is attached. Also one note: I use trial version (2010.1.309.35) of Rad controls.
Please let me known if there is way to resolve this trouble.
