Display progress bar in ASP. NET

For ASP. NET pages that have 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 typeProgram;
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: Visual C #. net Code
response. write ("

");
response. write ("_");
response. write ("

");
response. write ("");
response. write ("");
response. flush ();
thread. sleep (10000);

Visual Basic. Net code
Response. Write ("<Div id = 'mydiv '> ")
Response. Write ("_")
Response. Write ("</div> ")
Response. Write ("<SCRIPT> mydiv. innertext =''; </SCRIPT> ")
Response. Write ("<script language = JavaScript> ;")
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)

Enter:
<SCRIPT>
Hidewait ();
</SCRIPT>
