解决方案

我们只是碰到了这个问题，我的工作。我们解决这个问题的办法是首先获得DropDownLists的UniqueID。这基本上是一个客户端ID。里面那个ID的是，它是从选定在GridView的行的引用。唯一的问题是，它似乎增加2到行计数。所以，如果你选择第1行的DROPDOWNLIST，独特的ID将带您到第三排的参考。所以：

获取的唯一ID>但是拆分它，你需要让行>使用行数来获得你所需要的值。

I have a Dropdownlist in a Gridview and i have to show the records associated with every id.And the ID contains more than 10 records so how can i show them??

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                con.Open();
                var ddl = (DropDownList)e.Row.FindControl("DropDownList1");
                //int CountryId = Convert.ToInt32(e.Row.Cells[0].Text);
                SqlCommand cmd = new SqlCommand("select LastName from Profile_Master",        con);
                SqlDataAdapter da = new SqlDataAdapter(cmd);
                DataSet ds = new DataSet();
                da.Fill(ds);
                con.Close();
                ddl.DataSource = ds;
                ddl.DataTextField = "LastName";
                ddl.DataBind();

            }
        }

解决方案

We just ran into this issue where I work. Our way around this problem was to first get the DropDownLists UniqueID. This is basically a Client ID. Inside of that ID is a reference to the row of the GridView that it was selected from. THE ONLY PROBLEM is that it seems to add 2 to the row count. So if you select Row 1's DropdownList, the Unique ID will bring you a reference to the 3rd row. So:

Get the unique ID > Split it however you need to to get the row > use the row number to get the values you need.
