      </asp:TemplateField> 
     </Columns> 
      <AlternatingRowStyle BackColor="PaleGoldenrod" /> 
      </asp:GridView>

MY CS代码是：

DataSet dss = new DataSet(); 
    SqlConnection MyConnection = new SqlConnection("server=prog;database=mydatabase; UID=sa;PWD=nato123;"); 

    SqlCommand sqlcmd = new SqlCommand("select * from [Bill]", MyConnection); 

    SqlDataAdapter adp = new SqlDataAdapter(sqlcmd); 
    DataSet ds = new DataSet(); 
    adp.Fill(ds); 

    GridView1.DataSource = ds.Tables[0]; 

    GridView1.DataBind(); 
    }

而不是使用按钮OnClick事件，我会用OnCommand并通过项目索引在CommandArgument：

<asp:Button ID="Button1" runat="server" OnCommand="Button1_Command" CommandArgument='<%#Container.ItemIndex%>' />

代码隐藏：

protected void Button1_Command(object sender, CommandEventArgs e) 
{ 
    GridViewRow row = GridView1.Rows[(int)e.CommandArgument]; 
    if (row != null) 
    { 
     TextBox txt = row.FindControl("TextBox1") as TextBox; 
     if (txt != null) 
     { 
      string value = txt.Text; 
     } 
    } 
}
