第一行数据不返回

I have a Gridview loaded from a database. The Gridview has BoundFields, Buttons, Textboxes, and Dropdown lists. If I select any row but the first row I am able to collect the data from that row. If I select the first row I can see the 0 being pasted to the Method. The Dropdown list and the Textboxes give me their data, but the BoundFields do not.

我有一个从数据库加载的Gridview。Gridview有BoundFields、按钮、文本框和下拉列表。如果我选择了第一行之外的任何一行，我就能够从这一行中收集数据。如果我选择第一行，我可以看到将0粘贴到该方法。下拉列表和文本框提供了它们的数据，但BoundFields没有。

string txtFName = ((TextBox)GridViewListComp.Rows[grIndex].Cells[0].Controls[0]).Text;

...repeat same template for others...

…为别人重复同样的模板……
