How to define a limit to the movement of an object in a canvas?
It's because when you do this:
if (currentPosition.X > 1028) //this doesnt work
{
transform.X = clickPosition.X;
}
You use transform, that is a different instance than the transform you use. You instanciated a new RenderTransform just before:
draggableControl.RenderTransform = new TranslateTransform(transform.X, transform.Y);
This should works:
if (currentPosition.X > 1028)
{
((TranslateTransform)draggableControl.RenderTransform).X = clickPosition.X;
}
