C＃Gridview第一行數據不返回

Question

我有一個從數據庫加載的Gridview。 Gridview有BoundFields，Buttons，Textboxes和Dropdown列表。如果我選擇任何行，但第一行，我能夠從該行收集數據。如果我選擇第一行，我可以看到0被粘貼到方法。下拉列表和文本框給我他們的數據，但是BoundFields沒有。

ASP文件

<asp:GridView ID="GridViewListComp" runat="server" AutoGenerateColumns="False" BackColor="White" 
    BorderWidth="2px" Width="1500px"

代碼文件

protected void GridViewListComp_RowUpdated(object sender, GridViewUpdateEventArgs e) 
    { 

     int grIndex = e.RowIndex; 
     GridViewRow rowGr = GridViewListComp.Rows[grIndex]; 
     string txtFName = GridViewListComp.Rows[grIndex].Cells[0].Text; 
     string txtLName = GridViewListComp.Rows[grIndex].Cells[1].Text; 
     string txtDOB = GridViewListComp.Rows[grIndex].Cells[2].Text; 
     string txtPolicy = ((TextBox)GridViewListComp.Rows[grIndex].FindControl("txtPolicy")).Text; 

     DropDownList ddl = GridViewListComp.Rows[grIndex].FindControl("ddlStatus") as DropDownList; 

     //gets the value of Status Dropdown list 
     string valueStatus = ddl.SelectedValue.ToString(); //This gets the value of Status 


     string txtPaidAmt = ((TextBox)GridViewListComp.Rows[grIndex].FindControl("PAID_AMT")).Text;

嘗試的背後...

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

...重複別人相同的模板......
