c# - In WPF, what is the equivalent of Suspend/ResumeLayout() and BackgroundWorker() from Windows Forms -

if in function in code behind, , want implement displaying "loading..." in status bar following makes sense, know winforms nono:

statusbarmessagetext.text = "loading configuration settings...";             loadsettingsgriddata(); statusbarmessagetext.text = "done"; 

what winforms chapter 1 class 101, form won't display changes user until after entire function completes... meaning "loading" message never displayed user. following code needed.

form1.suspendlayout();     statusbarmessagetext.text = "loading configuration settings...";                 form1.resumelayout();  loadsettingsgriddata();  form1.suspendlayout();     statusbarmessagetext.text = "done"; form1.resumelayout(); 

what best practice dealing fundamental issue in wpf?

best , simplest:

using(var d = dispatcher.disableprocessing()) {     /* work... use dispacher.begininvoke... */ } 

or

idisposable d;  try {     d = dispatcher.disableprocessing();     /* work... use dispacher.begininvoke... */ } {     d.dispose(); }
