c# - How can I make a ListView update after each item is added? -

i trying use listview make realtime log output windows form.

this dummy code:

 public form1()     {         initializecomponent();         listview1.view = view.details;         listview1.gridlines = false;         listview1.scrollable = true;          listview1.fullrowselect = true;         listview1.columns.add("track");         listview1.columns.add("status");          (int = 1; <= 10000; i++)         {             listviewitem lvi = new listviewitem("track " + i);             lvi.subitems.add("updated");             listview1.items.add(lvi);             listview1.topitem = lvi;             listview1.ensurevisible(listview1.items.count - 1);         }     } 

how can set refreshes after each line added? @ moment application waits until list generated , loads form complete list.

you can fill data items in thread (for example using task):

application.doevents() ... processes window messages , redraws component.

 public form1()         {             initializecomponent();             listview1.view = view.details;             listview1.gridlines = false;             listview1.scrollable = true;              listview1.fullrowselect = true;             listview1.columns.add("track");             listview1.columns.add("status");              task t = new task(new action(() =>                 {                     refreshlines();                 }));             t.start();         }          public void refreshlines()         {             if (this.invokerequired)             {                 this.invoke(new methodinvoker(this.refreshlines));             }             (int = 1; <= 10000; i++)             {                 listviewitem lvi = new listviewitem("track " + i);                 lvi.subitems.add("updated");                 listview1.items.add(lvi);                 listview1.topitem = lvi;                 listview1.ensurevisible(listview1.items.count - 1);                 application.doevents();             }         } 

you can call this.refresh(); instead of application.doevents();
