C# 无法进行响应。重定向无法工作

我有这个简单的代码，我想检查客户类型是否为商业客户。否则，将出现错误。如果是，它将被引导到另一页。我是不是遗漏了什么

protected void Button1_Click(object sender, EventArgs e)
    {
        if ("Customer Type" != "Commercial Customer")
        {
            lblerror.Text = "For commercial customers only";
        }
        else
        {
            Response.Redirect("CreditRequestRegistration.aspx");
        }

    }

这是我的aspx代码：

              <table id="tblcustomerprofile" border="1" cellpadding="1" cellspacing="0">
                   <tr>

您正在比较两个明显不相等的字符串。else部分将如何执行？如果它们在gridview中，我如何比较它们？Customertype是标题，Commercial Customer在数据字段中。您可以使用foreach循环formview控件，并比较“Customer type”列中的文本。您可以给我一个示例吗？我真的非常感谢@parthat这会给你一些想法：
