在GridView中的检查项目不显示 [英] Checked items in gridview is not displayed

问题描述

在我的编码中，我使用带有复选框和列表框的gridview来获取选中的项目.但是选中的项目不会显示在istbox中.
我正在使用以下代码:

In my coding I''m using a gridview with check box and a list box to get the checked items. But the checked items are not displayed in istbox.
I''m using the following code:

protected void btSelect_Click(object sender, EventArgs e)
   {
       StringCollection sc = new StringCollection();
       string id = string.Empty;
       for (int i = 0; i < GridView1.Rows.Count; i++)
       {
           CheckBox cb = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("CheckBox1");
           if (cb != null)
           {
               if (cb.Checked)
               {
                   id = GridView1.Rows[i].Cells[1].Text;
                   sc.Add(id);
               }
           }
       }
       foreach (string item in sc)
       {
           productList.Items.Add(item);
       }
   }

我是否想念什么?

谢谢.

Whether I''m missing something?

Thankyou.

推荐答案

也许这会帮助 DataGridDemo [ ^ ]

尝试:

Try:

protected void btSelect_Click(object sender, EventArgs e)
{
        List<string> sc = new List<string>();
        string id = string.Empty;
        for (int i = 0; i < GridView1.Rows.Count; i++)
        {
            CheckBox cb = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("CheckBox1");
            if (cb != null)
            {
                if (cb.Checked)
                {
                    id = GridView1.Rows[i].Cells[1].Text;
                    sc.Add(id);
                }
            }
        }

        productList.DataSource = sc.ToArray();
        productList.DataBind();
}
