我想将具有5列的数据绑定到我准备的每个标签中。例如：
（row1，col1）绑定到label1 （row1，col2）绑定到label2
我的数据库中的行数可以有所不同，可以是5行，6行等。列正好是5。可以帮我修好代码吗？我需要在用户按下按钮时绑定它。
这是我的aspx代码

这是一个例子，如何循环gridview。
double tot = 0;
foreach (GridViewRow gvRow in GridView1.Rows)
{
Label lblGT = (Label)gvRow.FindControl("lblinvGrandTotal");
if (lblGT.Text != "")
{
tot += Convert.ToDouble(lblGT.Text);
}
}
