Question

I have a canvas on my WPF form that I need to run a sequence of images at Runtime. How do I refresh the images in the canvas?

Answer 1

Any changes you make to visual elements in a WPF application will be reflected in the view. You do not need to invoke a Refresh method to make changes visible. For your application you could create a DispatcherTimer, then either change your Image.Source or replace your Image on each Tick.

For example:

<Canvas>
  <Image x:Name="myImage" Source="SomeUri"/>
</Canvas>

And this code-behind:

var timer = new DispatcherTimer();
timer.Interval = TimeSpan.FromSeconds(1);
timer.Start();
timer.Tick += (s,e) =>
{
  myImage.Source = // next image in sequence
}
