How can I display the progress of an ASP. NET page that has been loaded for a long time in a client browser?
For an Asp.net page that has been loaded for a long time, we can display a progress bar in the client browser to show that the page is being loaded. The specific implementation process is as follows:
Create a project named webportal. In the project type, select Visual C # project or visual basic project;
Select an ASP. NET web application from the template type Program ;
Enter: http: // localhost/webportal;
Add a new project: A web form named showprogress.
Add any other Web server controls on your web form showprogress. aspx.
Right-click showprogress. aspx and click "View ". Code ", Enter at the top:
Visual C #. Net code
Using system. Threading;
Visual Basic. Net code
Imports system. threading
In the page_load event, enter the Visual C #. Net code.
Response. Write ("<Div id = 'mydiv '> ");
Response. Write ("_");
Response. Write ("</div> ");
Response. Write ("<SCRIPT> mydiv. innertext =''; </SCRIPT> ");
Response. Write ("<script language = <a href =" http://dev.21tx.com/web/javascript/ "target =" _ blank "> JavaScript </a> ;");
Response. Write ("Var DOTS = 0; var dotmax = 10; function showwait ()");
Response. Write ("{var output; Output = 'loading page'; DOTS ++; If (DOTS> = dotmax) DOTS = 1 ;");
Response. Write ("For (VAR x = 0; x <dots; X ++) {output + = '·';} mydiv. innertext = output ;}");
Response. Write ("function startshowwait () {mydiv. style. Visibility = 'visible ';");
Response. Write ("window. setinterval ('showwait ()', 1000 );}");
Response. Write ("function hidewait () {mydiv. style. Visibility = 'did ';");
Response. Write ("window. clearinterval ();}");
Response. Write ("startshowwait (); </SCRIPT> ");
Response. Flush ();
Thread. Sleep (10000 );
