How to set the dock property to resize all controls in page based on screen resolution?

Thanks for any help

Answer 1

Use the Anchor property and anchor the control to all 4 sides.

Answer 2

I hope this solution (drawn from here) will help display all the controls inside the form when the screen resolution changes at the client side:

int i_StandardHeight = 768;//Developer Desktop Height Where the Form is Designed
                int i_StandardWidth = 1024; ;//Developer Desktop Width Where the Form is Designed
                int i_PresentHeight = Screen.PrimaryScreen.Bounds.Height;
                int i_PresentWidth = Screen.PrimaryScreen.Bounds.Width;
                float f_HeightRatio = new float();
                float f_WidthRatio = new float();
                f_HeightRatio = (float)((float)i_PresentHeight / (float)i_StandardHeight);
                f_WidthRatio = (float)((float)i_PresentWidth / (float)i_StandardWidth);
                foreach (Control c in this.Controls)
                {
                    if (c.GetType().ToString() == "System.Windows.Forms.Button")
                    {
                        Button obtn = (Button)c;
                        obtn.TextAlign = ContentAlignment.MiddleCenter;
                    }
                    if (c.HasChildren)
                    {
                        foreach (Control cChildren in c.Controls)
                        {
                            cChildren.SetBounds(Convert.ToInt32(cChildren.Bounds.X * f_WidthRatio), Convert.ToInt32(cChildren.Bounds.Y * f_WidthRatio), Convert.ToInt32(cChildren.Bounds.Width * f_WidthRatio), Convert.ToInt32(cChildren.Bounds.Height * f_HeightRatio));
                            //cChildren.Font = new Font(cChildren.Font.FontFamily, cChildren.Font.Size * f_HeightRatio, cChildren.Font.Style, cChildren.Font.Unit, ((byte)(0)));
                        }
                        c.SetBounds(Convert.ToInt32(c.Bounds.X * f_WidthRatio), Convert.ToInt32(c.Bounds.Y * f_WidthRatio), Convert.ToInt32(c.Bounds.Width * f_WidthRatio), Convert.ToInt32(c.Bounds.Height * f_HeightRatio));
                       // c.Font = new Font(c.Font.FontFamily, c.Font.Size * f_HeightRatio, c.Font.Style, c.Font.Unit, ((byte)(0)));
                    }
                    else
                    {
                        c.SetBounds(Convert.ToInt32(c.Bounds.X * f_WidthRatio), Convert.ToInt32(c.Bounds.Y * f_WidthRatio), Convert.ToInt32(c.Bounds.Width * f_WidthRatio), Convert.ToInt32(c.Bounds.Height * f_HeightRatio));
                       // c.Font = new Font(c.Font.FontFamily, c.Font.Size * f_HeightRatio, c.Font.Style, c.Font.Unit, ((byte)(0)));
                    }
                }
                this.Height = Convert.ToInt32(i_StandardHeight * f_HeightRatio);
                this.Width = Convert.ToInt32(i_StandardWidth * f_WidthRatio);

In addition to setting the Dock property of the container Panel, you also have to set the Anchor or Dock properties of controls within the Panel. Usually, adding a TableLayoutPanel, FlowLayoutPanel, or even another Panel will help when you have multiple controls on a Form.
