Question

我的上下文菜单中的项目未执行。我的xaml：

        </DataGrid.Columns>


        <DataGrid.RowStyle>
            <Style TargetType="DataGridRow" BasedOn="{StaticResource {x:Type DataGridRow}}">
                <Setter Property="ContextMenu" Value="{StaticResource ContextMenu}" />
            </Style>
        </DataGrid.RowStyle>

    </DataGrid>
    <TextBox HorizontalAlignment="Left" x:Name="FilterString" Height="19" Margin="128,15,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="134"/>
    <Label Content="filtr odbiorca" HorizontalAlignment="Left" Height="26" Margin="17,15,0,0" VerticalAlignment="Top" Width="92"/>


</Grid>

我的视图模型-上下文菜单部分：

    public void Open(object source)
    {
        MessageBox.Show((string)source);
    }

我可以看到此上下文菜单，正如我在其他类似文章中所看到的那样，上下文菜单未与我的ViewModel连接，并且我不知道如何连接它。 Contextmenu应该使用选定的行作为参数进行一些操作。
