Slide to max page hight

Question

I have a slider and can fill in the slide length .

For example 300 or 400 .

In the code the length 550 what to fill in for the whole screen ?

var mainDisplayInfo = DeviceDisplay.MainDisplayInfo;


            if (MyDraggableView.Height == 0)
            {
                Action<double> callback = input => MyDraggableView.HeightRequest = input;
                double startHeight = 0;
                double endHeight = mainDisplayInfo.Height / 4;
                uint rate = 32;
                uint length = 550;
                Easing easing = Easing.CubicOut;
                MyDraggableView.Animate("anim", callback, startHeight, endHeight, rate, length, easing);
            }
            else
            {
                Action<double> callback = input => MyDraggableView.HeightRequest = input;
                double startHeight = mainDisplayInfo.Height / 4;
                double endiendHeight = 0;
                uint rate = 32;
                uint length = 550;
                Easing easing = Easing.SinOut;
                MyDraggableView.Animate("anim", callback, startHeight, endiendHeight, rate, length, easing);

            }

Answer 1

The MyDraggableView is the name of the slider , and this is the code of the slider itself in xaml.
This part is sliding up

                        </Grid>  
  
                    </ScrollView>  
                </PanCake:PancakeView>  

And this is the slider , but i want to slide it al the way up , on every phone .
