Today, I would like to talk to you about the two noteworthy places in the process of ASP.NET development, which many people may not know. In order to make you understand better, the editor summarized the following content for you. I hope you can get something according to this article.

There are two strange things about the Page_Load event on an ASPX page in an ASP.NET development program that you should remember:

a. Sometimes Page_Load events occur multiple times on your ASP.NET page. One possible reason for this is that you set the AutoEvenWireup value of the ASPX page to True. If so, it is unnecessary to add the line "Handles MyBase.Load" after "Sub Page_Load (ByVal Sender as System.Object,ByVal e as System.EventArgs"). Since Visual Studio.NET can automatically handle this part for you, you can of course set the AutoEventWireup value to False.

b. Sometimes it's as if the click event handling code for a button is not running. Here you should check the Page_Load event to make sure that any ASP.NET developer code that loads data (for example, code that binds data in a drop-down list) runs only when the page is initially loaded, not later when the client data is returned. An easy way to check this is to add a test to your Page_load event handler for the page. IsPostBack value-False means that the page has been loaded * and True means that a data return process has taken place.

After reading the above, do you have any further understanding of which of the two noteworthy aspects of the ASP.NET development process are? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
