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变化，可以是 5 行、6 行等。列正好是 5。能帮我看看后面的代码吗？当用户按下按钮时，我需要绑定它。

这是我的aspx代码

<div style="margin-top:10px; border:solid 2px #7bc1f7; border-radius:20px; padding:10px;">

这是一个示例，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);
        }
    }
