Question

I need somehow pass double fromH, double toH, UIElement control to the AnimateH method within of sb.Completed but I got the error

The name ‘toW’ does not exist in the current context issue

and etc..

How do i can fix it?

Thank you!

 void AnimateTop(double from, double to, double fromH, double toH, UIElement control)
        {
            Debug.WriteLine("EFM - AnimateTop - from: " + from.ToString() + " to: " + to.ToString());
            Storyboard sb = new Storyboard();
            DoubleAnimation da = new DoubleAnimation();
            da.From = from;
            da.To = to;
            da.Duration = new Duration(TimeSpan.FromSeconds(1));
            sb.Children.Add(da);
            Storyboard.SetTargetProperty(da, new PropertyPath("(Canvas.Top)"));
            Storyboard.SetTarget(da, control);
            sb.Completed += (w, r) => 
            { 
                AnimateH(fromW, toW, control); // Here is the error
                control.UpdateLayout(); 
            };
            sb.Begin();
        }

You’re using toW but it’s not declared anywhere
or passed as parameter

If it’s a value that comes from another place, you should passed as a parameter. If it’s a value created from some method there, you should declare the type and get its value

TypeOftoW toW = MethodThatReturntoWValues();

before using it.
