WPF DataGridRow ContextMenu MenuItem单击事件未触发

Question

我有一个带有上下文菜单的DataGrid，该菜单只能从行访问。 我从这个StackOverflow Answer获得解决方案。 我需要将上下文菜单绑定到行，因为click方法需要选择特定的行。 行上的上下文菜单看起来很好用。 现在的问题是菜单项的单击事件没有触发。 有人知道如何解决此问题吗？

XAML：

<DataGrid x:Name="NetworkEntryGrid" Margin="10,10,10,0" CanUserResizeColumns="True" CanUserReorderColumns="False" ColumnWidth="*" IsReadOnly="True" IsManipulationEnabled="False">
    <DataGrid.Resources>
        <Style TargetType="DataGridRow">
            <Setter Property="ContextMenu">
                <Setter.Value>
                    <ContextMenu>
                        <MenuItem Header="Install As">
                            <MenuItem x:Name="InstallLabelsMenuItem" Header="Labels" Click="InstallLabelsMenuItem_Click"/>
                            <MenuItem x:Name="InstallATagsMenuItem" Header="A Tags" Click="InstallATagsMenuItem_Click"/>
                            <MenuItem x:Name="InstallSpecialLabelsMenuItem" Header="Special Labels" Click="InstallSpecialLabelsMenuItem_Click"/>
                            <MenuItem x:Name="InstallReportsMenuItem" Header="Reports" Click="InstallReportsMenuItem_Click"/>
                            <MenuItem x:Name="InstallPawnTicketsMenuItem" Header="Pawn Tickets" Click="InstallPawnTicketsMenuItem_Click"/>
                            <MenuItem x:Name="InstallReceiptsMenuItem" Header="Receipts" Click="InstallReceiptsMenuItem_Click"/>
                        </MenuItem>
                        <MenuItem Header="Copy">
                            <MenuItem x:Name="CopyNameMenuItem" Header="Name" Click="CopyNameMenuItem_Click"/>
                            <MenuItem x:Name="CopyIpMenuItem" Header="IP" Click="CopyIpMenuItem_Click"/>
                            <MenuItem x:Name="CopyMacMenuItem" Header="MAC Address" Click="CopyMacMenuItem_Click"/>
                            <MenuItem x:Name="CopyVendorMenuItem" Header="Vendor" Click="CopyVendorMenuItem_Click"/>
                        </MenuItem>
                    </ContextMenu>
                </Setter.Value>
            </Setter>
        </Style>
    </DataGrid.Resources>
</DataGrid>

我将MessageBox和WriteLine命令添加到click事件方法中，以确保它们不会显示。

C＃：

private void InstallLabelsMenuItem_Click(object sender, RoutedEventArgs e)
{
    Console.WriteLine("Labels Clicked");
    MessageBox.Show("Labels Clicked", "Menu Item Event", MessageBoxButton.OK);
    AssignPrinter("Labels");
}

将ContextMenu添加为Resource并将其作为StaticResource引用。

<DataGrid x:Name="NetworkEntryGrid" Margin="10,10,10,0" CanUserResizeColumns="True" CanUserReorderColumns="False" ColumnWidth="*" IsReadOnly="True" IsManipulationEnabled="False">
    <DataGrid.Resources>
        <ContextMenu x:Key="contextMenu">
            <MenuItem Header="Install As">
                <MenuItem x:Name="InstallLabelsMenuItem" Header="Labels" Click="InstallLabelsMenuItem_Click"/>
                <MenuItem x:Name="InstallATagsMenuItem" Header="A Tags" Click="InstallATagsMenuItem_Click"/>
                <MenuItem x:Name="InstallSpecialLabelsMenuItem" Header="Special Labels" Click="InstallSpecialLabelsMenuItem_Click"/>
                <MenuItem x:Name="InstallReportsMenuItem" Header="Reports" Click="InstallReportsMenuItem_Click"/>
                <MenuItem x:Name="InstallPawnTicketsMenuItem" Header="Pawn Tickets" Click="InstallPawnTicketsMenuItem_Click"/>
                <MenuItem x:Name="InstallReceiptsMenuItem" Header="Receipts" Click="InstallReceiptsMenuItem_Click"/>
            </MenuItem>
            <MenuItem Header="Copy">
                <MenuItem x:Name="CopyNameMenuItem" Header="Name" Click="CopyNameMenuItem_Click"/>
                <MenuItem x:Name="CopyIpMenuItem" Header="IP" Click="CopyIpMenuItem_Click"/>
                <MenuItem x:Name="CopyMacMenuItem" Header="MAC Address" Click="CopyMacMenuItem_Click"/>
                <MenuItem x:Name="CopyVendorMenuItem" Header="Vendor" Click="CopyVendorMenuItem_Click"/>
            </MenuItem>
        </ContextMenu>
        <Style TargetType="DataGridRow">
            <Setter Property="ContextMenu" Value="{StaticResource contextMenu}"/>
        </Style>
    </DataGrid.Resources>
</DataGrid>
