.NET支持上下左右移动操作

效果如下图：

代码如下：

   public partial class ShowSet : System.Web.UI.Page
    {

        private string names = null;

                initi18n();

                string[] all =string.IsNullOrEmpty(names)?null: names.Split(',');//分割出所有列
                hidfShows.Value =ini.IniValue("Set", "Show");
                string include = hidfShows.Value;//获取当前页展示列
                if (string.IsNullOrEmpty(names)||all == null)
                {

                }
                for (int i = 0; i < all.Length; i++)//遍历所有列
                {
                    if (include.IndexOf("@" + all[i] + "@") == -1)//当前列中不包含分割出来的列时放在不显示框中
