解决方案 »

  1.   

     // 增加单项
        protected void AddBtn_Click(object sender, EventArgs e)
        {
            ArrayList MyAl = new ArrayList();
            for (int i = AddListBox.Items.Count - 1; i >= 0; i--)
            {
                ListItem list = AddListBox.Items[i];
                if (AddListBox.Items[i].Selected)
                {
     //移除单项
        protected void DropBtn_Click(object sender, EventArgs e)
        {
            ArrayList MyAl = new ArrayList();
            for (int i = DropListBox.Items.Count - 1; i >= 0; i--)
            {
                ListItem list = DropListBox.Items[i];
                if (DropListBox.Items[i].Selected)
                {
      //增加所有
        protected void AddAllBtn_Click(object sender, EventArgs e)
        {
            ArrayList MyAl = new ArrayList();
            for (int i = AddListBox.Items.Count - 1; i >= 0; i--)
            {
                ListItem list = AddListBox.Items[i];
       //移除所有
        protected void DropAllBtn_Click(object sender, EventArgs e)
        {
            ArrayList MyAl = new ArrayList();
            for (int i = DropListBox.Items.Count - 1; i >= 0; i--)
            {
                ListItem list = DropListBox.Items[i];
      

  2.   

    这个应该很简单吧   数据库有一个识别的字段 当A=1绑定a  listbox,A=0绑定b listbox ，其他的按钮是就update语句的操作了!
