Hi,
I have an asp html page that allows the user to input data into a web page. When they click the submit button it calls a default.aspx.vb. The ISPostback is always false so it skips my sql add parameters. Here is the code:

推荐答案
第一件事，为什么要在页面加载中编写逻辑?您正在通过按钮单击提交页面-定义单击处理程序，并在该单击事件方法中将保存数据写入DB逻辑中.
顺便说一句，请记住将AutoEventWireUp设置为"true"以处理自动点击事件.
First thing, why to write a logic in pageload? You are submitting a page via button click - define click handler and write the save data in DB logic in that click event method.
BTW, do remember to set AutoEventWireUp to ''true'' to have automatic click event handled.
