Errors when tear off a tab inside a page #225

Closed ha-nso-li closed 4 years ago

ha-nso-li commented 5 years ago

It raises exceptions when I tear off a tab. 'TabablzControl' is in 'Page' control.

MainWindow.xaml

<Frame NavigationUIVisibility="Hidden" Grid.Row="0" Grid.Column="1" Content="{Binding MyPage}" />

And I set 'ImagePage' as 'MyPage' from view model.

ImagePage.xaml

<Grid>
    <dragablz:TabablzControl Margin="8">
        <dragablz:TabablzControl.InterTabController>
            <dragablz:InterTabController />
        </dragablz:TabablzControl.InterTabController>
        <TabItem Header="Tab No. 1" IsSelected="True">
            <TextBlock>Hello World</TextBlock>
        </TabItem>
        <TabItem Header="Tab No. 2">
            <TextBlock>We Have Tearable Tabs!</TextBlock>
        </TabItem>
    </dragablz:TabablzControl>
</Grid>

Exception (in Korean)

It seems this problem is similar to #117 but it isn't.

App.xaml

<Style TargetType="{x:Type dragablz:TabablzControl}" BasedOn="{StaticResource MaterialDesignTabablzControlStyle}">
    <Setter Property="Background" Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=Page}, Path=Background}" />
    <Setter Property="TextElement.Foreground" Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=Page}, Path=(TextElement.Foreground)}" />
</Style>

When I fix AncestorType from Window to Page, System.Windows.Data error is gone but an exception was still raised.

Enviroment: C# 4.7.2 Dragablz v0.0.3.203, MahApps.Metro v1.6.5, MaterialDesignThemes v2.5.1, Prism v7.10.431 etc.... All libraries are installed from NuGet.

Workaround: I temporary disabled tearable tab feature. (see #115)

Closing the issue that I'm not interested in anymore. + It seems the project is inactive and abandoned.
