WPF DataGridRow ContextMenu MenuItem单击不触发事件

我有一个DataGrid，其上下文菜单只能从行中访问。我从this StackOverflow Answer得到了解决方案。我需要将上下文菜单绑定到行，因为点击方法需要选择特定的行。行上的上下文菜单很好看。问题是现在菜单项的点击事件不会触发。有人知道如何解决这个问题吗？WPF DataGridRow ContextMenu MenuItem单击不触发事件

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>

我添加一个MessageBox和WriteLine命令的单击事件的方法，以确保但他们不露面。

C＃：

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

将它标记为答案，如果它可以帮助你 –

添加ContextMenu作为Resource并引用其作为StaticResource。

<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>
