I tried adding "Onclick = "submit" to the asp.net code but it kept through an error.
Any help would be very much appreciated.
Thank you for your time and help.
我尝试在 asp.net 代码中添加“Onclick =”submit”，但它仍然通过一个错误。
任何帮助将不胜感激。感谢您的时间和帮助。

There are two ways to wire up this button event. The first would be in code behind by modifying your signature to add the Handleskeyword:
有两种方法可以连接此按钮事件。第一个将通过修改您的签名以添加Handles关键字来隐藏在代码中：
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
The second would be in the html side by defining the onClick event to be assigned to the function itself
第二个将在 html 端通过定义要分配给函数本身的 onClick 事件
<asp:Button ID="Button1" runat="server" Text="Button" onClick="Button1_Click" />
