WPF-右键菜单ContextMenu

示例：

        <Button Margin="10,10,0,0" VerticalAlignment="Top" HorizontalAlignment="Left" Content="按钮_具有右键菜单">
            <Button.ContextMenu>
                <ContextMenu StaysOpen="true">
                    <MenuItem Header="File"/>
                    <MenuItem Header="Save"/>
                    <Separator/>
                    <MenuItem Header="Recent Files">
                        <MenuItem Header="ReadMe.txt"/>
                        <MenuItem Header="Schedule.xls"/>
                    </MenuItem>
                </ContextMenu>
            </Button.ContextMenu>
        </Button>

后台：

            Dictionary<string, RoutedEventHandler> dist = new Dictionary<string, RoutedEventHandler>();
            //添加右键菜单项，包括名称和事件
            dist.Add("添加", add_Click);
            dist.Add("修改", edit_Click);
            dist.Add("删除", del_Click);
            dist.Add("导出", putout_Click);
            dgrid.ContextMenu = ContextMenus(dist);
