How to auto resize and adjust Form controls with change in resolution

Question

I have noticed that some applications change their controls position to adjust them as much as possible in the resolution as possible, If window is maximized they set themselves in such a way that over all GUI looks balanced. My question is that is it possible to make or implement this functionality in Visual studio 2010 C#?

Answer 1

Use Dock and Anchor properties. Here is a good article. Note that these will handle changes when maximizing/minimizing. That is a little different that if the screen resolution changes, but it will be along the same idea.

Answer 2

Use combinations of these to get the desired result:

1. Set Anchor property to None, the controls will not be resized, they only shift their position.

2. Set Anchor property to Top+Bottom+Left+Right, the controls will be resized but they don't change their position.

3. Set the Minimum Size of the form to a proper value.

4. Set Dock property.

5. Use Form Resize event to change whatever you want

I don't know how font size (label, textbox, combobox, etc.) will be affected in (1) - (4), but it can be controlled in (5).

Answer 3

float widthRatio = Screen.PrimaryScreen.Bounds.Width / 1280;
float heightRatio = Screen.PrimaryScreen.Bounds.Height / 800f;
SizeF scale = new SizeF(widthRatio, heightRatio);
this.Scale(scale);
foreach (Control control in this.Controls)
{
control.Font = new Font("Verdana", control.Font.SizeInPoints * heightRatio * widthRatio);
}

Answer 4

..and to detect a change in resolution to handle it (once you're using Docking and Anchoring like SwDevMan81 suggested) use the SystemEvents.DisplaySettingsChanged event in Microsoft.Win32.

Here I like to use https://www.netresize.net/index.php?c=3a&id=11#buyopt. But it is paid version.

You also can get their source codes if you buy 1 Site License (Unlimited Developers).

How ever I am finding the nuget package solution.

Answer 6

sorry I saw the question late, Here is an easy programmatically solution that works well on me,

Create those global variables:

 float firstWidth;
 float firstHeight;

after on load, fill those variables;

 firstWidth = this.Size.Width;
 firstHeight = this.Size.Height;

then select your form and put these code to your form's SizeChange event;

 private void AnaMenu_SizeChanged(object sender, EventArgs e)
    {
        

        float size1 = this.Size.Width /  firstWidth;
        float size2 = this.Size.Height / firstHeight;

            SizeF scale = new SizeF(size1, size2);
        firstWidth = this.Size.Width;
        firstHeight = this.Size.Height;

        foreach (Control control in this.Controls)
        {
                
            control.Font = new Font(control.Font.FontFamily, control.Font.Size* ((size1+ size2)/2));
            
            control.Scale(scale);
                

        }


    }

I hope this helps, it works perfect on my projects.

Answer 7

add this code at page load do for all control or add all control in containers

int x;
Point pt = new Point();
x = Screen.PrimaryScreen.WorkingArea.Width - 1024;
x = x / 2;
pt.Y = groupBox1.Location.Y + 50;
pt.X = groupBox1.Location.X + x;
groupBox1.Location = pt;

Answer 8

in the form load event add this line

this.WindowState = FormWindowState.Maximized;

Answer 9

private void MainForm_Load( object sender, EventArgs e ) 
     { 
        this.Size = Screen.PrimaryScreen.WorkingArea.Size 
     }

Answer 10

this.WindowState = FormWindowState.Maximized;
