Gridview - Child element

Note: This is how they are created. I'm trying to iterate throw them outside the below override function

  protected override void CreateChildElements()
            {
                base.CreateChildElements();
                stack = new StackLayoutElement();
                stack.Orientation = Orientation.Horizontal;
                stack.StretchHorizontally = true;

                checkBoxElement.StretchHorizontally = false;
                checkBoxElement.CheckStateChanged += checkBoxElement_CheckStateChanged;
                textElement.TextAlignment = ContentAlignment.MiddleLeft;
                this.Children.Add(stack);
                stack.Children.Add(checkBoxElement);
                stack.Children.Add(textElement);


                ///////////
                pro.StretchHorizontally = false;
                pro.AutoSize = false;
                pro.Size = new Size(250, 45);//48
                pro.Alignment = ContentAlignment.MiddleRight;
                pro.Margin = new Padding(0, 0, 0, 5);

                pro.HighlightColor = Color.FromArgb(191, 219, 255);
                stack.Children.Add(pro);                
            }
