如何获取当前编辑行上（下）一项的ID呢？

Question

(Convert.ToInt64(GridView1.DataKeys[GridView1.SelectedIndex].Value.ToString()))这个是当前编辑行的ID，对吗？那么如何获取这一行的上（下）项的ID呢？

Answer 1

GridView1.SelectedIndex是选中的行，上下行GridView1.SelectedIndex-1获取+1不就行了

Answer 2

我是想在GRIDVIEW里面得到不连续ID、连续顺序的两条数据的ID号！

Answer 3

(Convert.ToInt64(GridView1.DataKeys[GridView1.SelectedIndex].Value.ToString()))
//GridView1.SelectedIndex-1取的不行.它就是表中上一条数据.

Answer 4

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        switch (e.CommandName)
        {
            case "ViewDetails":
                // 查看详细
                Response.Redirect("DownloadViewDetails.aspx?did=" + GridView1.Rows[Convert.ToInt32(e.CommandArgument)].Cells[0].Text);
                break;
            case "MoveDown":                using (ExtDownloads downloads = new ExtDownloads())
                {
                        long dID1 = (Convert.ToInt64(GridView1.DataKeys[GridView1.SelectedIndex].Value.ToString())); 
                        long dID2 = (Convert.ToInt64(GridView1.DataKeys[GridView1.SelectedIndex + 1].Value.ToString()));
                        downloads.MoveDown(Convert.ToInt64(dID1), Convert.ToInt64(dID2));                }
                BindData();
                break;
        }
    }这里我已经绑定已经绑定了DataKeysnames,不过还是提示索引超出范围，什么回事呢？
