How to update the parent's (stacklayout) autosizing? (Solved)

[WileyNg]

I made a custom-made expander box but i am getting a hard time to update the parent's autosizing, after the expander is expanded.
Is it possible to shed some light for me on this?

        public void OnExpanded()
        {
            Content = expanded ? Control : new DynamicLayout();
            
            int _ContentSize = (int)Content.GetPreferredSize().Height + (Padding * 4) + (int)textSize.Height;
            Height = _ContentSize;
            DrawGraphics();
            Parent.Parent.Invalidate(); ;
            Invalidate();
        }

I made a method which is called when the Header is clicked(MouseUp).
The collapsed expander will just have an empty DynamicLayout, while the expanded one will have all the controls.
The height I get it with a GetPreferredSize.

The problem is, the control (StackLayout) which the Custom-Expander is nested in, doesn't adjust the sizing itself whenever the child control height is changed.

I tried to call Invalidate() function for the StackLayout by finding the Parents of the custom-expander, but in vain.
