Question

i have a situation where : User moves mouse over the image .

If user keeps mouse on that image for specific time ex. 2 seconds then only i have to proceed

further in mouseenter event otherwise don’t.

I have already refred to http://forums.silverlight.net/t/86671.aspx/1 but looks like mine is different case.

Answer 1

One option is to use a DispatchTimer to determine the length of the mouse over.

bool isMouseOverImage = false;
public void Image_MouseEnter(object sender, MouseEventArgs e)
{
  this.isMouseOverImage = true;
  var timer = new System.Windows.Threading.DispatcherTimer();
  timer.Interval = TimeSpan.FromSeconds(2);
  timer.Tick += (object timerSender, EventArgs timerArgs) =>
  {
     if(this.isMouseOverImage)
     {
       // write your code 
     }

     // stop the timer
     timer.Stop();     
  };
  timer.Start();
}

public void Image_MouseLeave(object sender, MouseEventArgs e)
{
  this.isMouseOverImage = false;
}

If you have multiple images, you should create a re-usable Behavior and attach it to each image. I can define code for that if that would help.
