Chrome Glass Border - Drag'n Drop Problem | myCSharp.de

MusiuminCapitiss

Hallo zusammen

Ich hab wieder ein Problem mit dem Glass Border.
Wenn ich bei meiner Applikation folgenden style Lade:

XML-Code:

<Style TargetType="{x:Type ribbon:Ribbon}">

        <Setter Property="Background" Value="Transparent"></Setter>

    </Style>

    <Style TargetType="{x:Type v:Shell}">

        <Setter Property="shell:WindowChrome.WindowChrome">

            <Setter.Value>

                <shell:WindowChrome CornerRadius="0" ResizeBorderThickness="10" GlassFrameThickness="-1" CaptionHeight="30"></shell:WindowChrome>

            </Setter.Value>

        </Setter>

        <Setter Property="Template" Value="{DynamicResource ChromeWindowContent}"></Setter>

    </Style>

    <ControlTemplate TargetType="{x:Type v:Shell}" x:Key="ChromeWindowContent">

        <Grid>

            <ContentPresenter x:Name="content" Margin="3,8,3,3" Content="{TemplateBinding Content}" ></ContentPresenter>

        </Grid>

        <ControlTemplate.Triggers>

            <Trigger Property="WindowState" Value="Maximized">

                <Setter Property="Margin" Value="8,8,8,8" TargetName="content"></Setter>

            </Trigger>

        </ControlTemplate.Triggers>

    </ControlTemplate>

Enden All Drag'n Drop Aktionen mit einem Exception.

...Ohne Glass Efekt funktionieren alle Drag'nDrop Aktionen.

Wenn ich den Style nicht lade, funktionieren alles wunderbar.
Mein OS ist Win7 x64.
