winforms - How to use mousehover delay in c#? -

i using mousehover click in c# want wait 2-3 sec before click , if cursor not stay on button 2 or more seconds, won't click.

you implement functionality deriving button class:

using system; using system.windows.forms;  namespace mousehoverdelay {     public class hoverbutton : button     {         protected system.timers.timer timer;          public bool ishoverenabled { get; set; }         public double delay { get; set; }          public event system.timers.elapsedeventhandler timerelapsed         {             add             {                 timer.elapsed += value;             }             remove             {                 timer.elapsed -= value;             }         }          public hoverbutton()         {             // defaults: hover trigger enabled 3000 ms delay             ishoverenabled = true;             delay = 3000;              timer = new system.timers.timer             {                 autoreset = false,                 interval = delay             };         }          protected override void onmouseenter(eventargs e)         {             base.onmouseenter(e);              if (ishoverenabled)             {                 timer.start();             }         }          protected override void onmouseleave(eventargs e)         {             base.onmouseleave(e);              timer.stop();         }     } } 

after adding form need set it's delay , handler method inside initializecomponent() method of form:

this.btnhovertest.delay = 2000; this.btnhovertest.timerelapsed += timer_elapsed; 

and implement handler in form:

using system; using system.windows.forms;  namespace mousehoverdelay {     public partial class form1 : form     {         public form1()         {             initializecomponent();         }          // triggers when delay milliseconds have passed since hovering mouse on control         protected void timer_elapsed(object o, eventargs e)         {             messagebox.show("hovered 2 seconds!");         }     } }
