导出为 CSV 时网格视图空行

这个问题是由对这个问题的进一步讨论引起的。

以下是我用于创建 CSV 文件的例程。一切都很好，除了我只得到列标题而没有行。

   protected void CSVReport_Click(object sender, EventArgs e)
    {
        Response.Clear();
        Response.Buffer = true;
        Response.AddHeader("content-disposition", "attachment;filename=PeopleReportTest.csv");
        Response.Charset = "";
        Response.ContentType = "text/csv";
        Response.AddHeader("Pragma", "public");
       GridView1.AllowSorting = false;
       GridView1.AllowPaging = false;
       GridView1.DataBind();
        StringBuilder sb = new StringBuilder();
        for (int k = 1; k < GridView1.Columns.Count; k++)
        {
            //add separator
            sb.Append(GridView1.Columns[k].HeaderText + ',');
        }
        //append new line
        sb.Append("'r'n");
        for (int i = 0; i < GridView1.Rows.Count; i++)
        {
            for (int k = 1; k < GridView1.Columns.Count; k++)
            {
                //add separator
                sb.Append(GridView1.Rows[i].Cells[k].Text + ',');
            }
            //append new line
            sb.Append("'r'n");
        }
        Response.Output.Write(sb.ToString());
        Response.Flush();
        Response.End();
    }

在检查时，我可以看到GridView1.Rows[i].Cells[k].Text总是返回一个空值。

所以问题可能出在我的网格视图的结构上。我知道如果我有TemplateFields代码将不起作用，但我只有一个并且它设置为不可见。

所有其他字段均DynamicFields 。这可能是问题所在吗？

下面是标记：

            CssClass="table table-condensed borderless"

                <asp:DynamicField DataField="PartnerSurname" HeaderText="Partner"/>
            </Columns>
            <PagerStyle CssClass="footer" />
            <PagerTemplate>
                <asp:GridViewPager runat="server" />
            </PagerTemplate>
            <EmptyDataTemplate>
                There are currently no items in this table.
            </EmptyDataTemplate>
</asp:GridView>
