Background: when loading data on a page in an Asp.net project, if loading data is slow, the page will be blank and some information will be searched online, all of them are simulated using JS, and it has not been found for a while.
So I thought about it myself and wrote it myself.
Implementation principle:
Add an updatepanel on the page, and add updateprogress to it. Add an animation page during loading, and add a button in updatepanel to simulate click events. Dizzy, I can't understand it. Go to the Code directly. The Code is as follows:
Front-end code:
<% @ Page Language = "C #" autoeventwireup = "true" codebehind = "devdetailpage. aspx. cs" inherits = "manageservice. devdetailpage" %> <! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <HTML xmlns = "http://www.w3.org/1999/xhtml">Background code:
Protected void loaddata_click (Object sender, eventargs e) {If (request. querystring. Count> 0) {// binddata (); alldata. Visible = true ;}}To sum up, add a button in updatepanel and execute the button event during loading to obtain data,
I think this method is still not very good. If there is a better method, please describe it.
