c# - ASP.NET WEBForms - see steps in real time -

let's assume have page button. on button click have event function called.

    protected void btnclick(object sender, eventargs e)     {         panelsteps.visible = true;         panelsteps_detailsaboutrecords.controls.add(new literal { text = "dads"});         system.threading.thread.sleep(5000); // wait 5 seconds         panelsteps_detailsaboutrecords.controls.add(new literal { text = "bda" });         system.threading.thread.sleep(5000); // wait 5 seconds         panelsteps_detailsaboutrecords.controls.add(new literal { text = "cdsa" });         system.threading.thread.sleep(5000); // wait 5 seconds         panelsteps_detailsaboutrecords.controls.add(new literal { text = "ddsa" });         system.threading.thread.sleep(5000); // wait 5 seconds         panelsteps_detailsaboutrecords.controls.add(new literal { text = "dase" });     } 

in browser see panel after entire function executed. why? , how can see in browser steps function in real time?

you have client-server architecture client web browser , server c# "server-side" code executes. server-side code, listed in op, finishes , bundled "response" object before client sees it.
