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);

        #region 循环生成右键菜单
        private ContextMenu ContextMenus(Dictionary<string, RoutedEventHandler> list)
        {
            ContextMenu cm = new ContextMenu();
            //Style style = (Style)this.FindResource("ContextMenu"); //定义前台显示模板
            //cm.Style = style;
            foreach (var dc in list)
            {
                MenuItem menu = new MenuItem();
                //menu.Style = (Style)this.FindResource("JjxyMenuItem");
                menu.Header = dc.Key;
                menu.Click += dc.Value;
                cm.Items.Add(menu);
            }

            return cm;
        }
