wpf与ItemTemplate的依赖

Question

我需要在下面的TextBlock中显示选定的RibbonMenuButton的值。 RibbonMenuButton的项目定义为ItemTemplate。如何在路径中定义引用？我用“ xxx”标记了

<ribbon:RibbonMenuButton ItemsSource = "{Binding Path=CompaniesList.Companies}" x:Name="rbtnCompanies" Label="{x:Static resources:ConsoliaJPK.SELECT_COMPANY}" SmallImageSource="Resources/Images/Check32.png" Margin="16,0,-15.604,-0.264">
    <RibbonMenuButton.ItemTemplate>
        <DataTemplate>
            <TextBlock x:Name="tblCompany" Text="{Binding Path=Name}" PreviewMouseLeftButtonDown="tblCompany_PreviewMouseLeftButtonDown" >                                        
            </TextBlock>
        </DataTemplate>
    </RibbonMenuButton.ItemTemplate>
</ribbon:RibbonMenuButton>
<TextBlock Text = "{Binding  ElementName=rbtnCompanies, Path=xxx}" Margin="41,6,-132,-6.604"></TextBlock>

Answer 1

我想rbtnCompanies.xxx应该包含Name。您可以在您的tblCompany_PreviewMouseLeftButtonDown中进行此分配。
