WPF DataGridRow ContextMenu MenuItem單擊事件未觸發

Question

我有一個帶有上下文菜單的DataGrid，該菜單只能從行訪問。 我從這個StackOverflow Answer獲得解決方案。 我需要將上下文菜單綁定到行，因為click方法需要選擇特定的行。 行上的上下文菜單看起來很好用。 現在的問題是菜單項的單擊事件沒有觸發。 有人知道如何解決此問題嗎？

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>

我將MessageBox和WriteLine命令添加到click事件方法中，以確保它們不會顯示。

C＃：

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

將ContextMenu添加為Resource並將其作為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>
