I have a problem with getting my content in a WinForm application to properly resize to fit any screen resolution, How can I solve this?
I used
this.Location = new Point(0, 0);
this.Size = Screen.PrimaryScreen.WorkingArea.Size;
The size of the form was successfully changed according to the computer's resolution but the contents were not.
The controls inside of a WinForms form do not change based on the size of the form. Textboxes, radio buttons, etc are based on a specific pixel size and do not vary by resolution.
You have to develop your form to work with different resolutions. You will want to use lots of panels with the DockStyle set appropriately. You can hide panels that won't fit (though you might need to provide an alternate way to get to them).
If you need it to change based on resolution, you might want to look into WPF.
For winforms Dock and Anchor properties can help you on this. But they are not powerful as new WPF features (Eg: viewBox). Containers like SplitContainer and Panels can be resized properly with the Dock property. But there is no easy+nice ways to resize child controls like buttons, labels. Those child controls are also support for Dock/Anchor properties though.
Below are some useful articles for your reference.

I have created a c# windows forms program with a Form which includes a Diagram, an image and Buttons. When I open the program the Form to big for the computer screen this is because the screen resolution is to big or to small.
How can I make the Form exactly right for each screen resolution type whiteout using sizable?
The problem is because you define (Pixel) sizes for your controls and therefore also your Form.
You can put your space consuming controls (diagrams, images) into Panels and then set the Dock property appropriately (on the controls and/or the panels) so that they scale out to their maximum size. This way you can reduce the size of the Form and because you define ratios rather than pixel numbers the controls/labels will expand as needed.
Depending on how you want it to look like you will have to play with different configurations (one or two controls in one label and then setting dock either to fill or left/right/top/bottom). There's also the SplitContainer control to help you achieve certain design goals.
Additionally, if you always want the perfectly scaled window, open the form in Maximised mode:
this.WindowState = System.Windows.Forms.FormWindowState.Maximized;
I want to make the backgroundImage of my tabPages spread out to the available size.
According to other topics here on StackOverflow, I set the BackgroundImageLayout in my Forms properties to Stretch, but my background image is still being displayed as a tile.
Is there another flag I have to set? I feel like the seemingly global property does not quite affect tabPages.
PS: If it is of any significant matter, the picture is being added at runtime.
EDIT: This is how my Picture is being added to the tabpage as background:
TabPage tab = new TabPage();
tab.BackgroundImage = Image.FromFile(*path*);
tabControl.TabPages.Add(tab);
while tabControl is passed as a parameter inside the class, coming straight from my Form via this.tabControl
The fetching of the image works.
Also, the stretch attribute is currently set inside the forms properties.
a BackgroundImage object has more properties, and one of those is the placement of the image constrains... the available layouts are:
None
Tile
Center
Stretch
Zoom
play with those and choose the one that fit your needs:
tab.BackgroundImageLayout = ImageLayout.Stretch;
as it probably be a fixed layout, you can also use the UI for given the correct layout, but it's up to you...
I have a WinForms Application that was designed to support Full HD resolutions (so 1920x1080). Now this App is also supposed to run on a lower resolution: 1600x900.
Is there a way to let the application auto scale itself to fit the lower resolution? Like you would just downscale an image, basically resizing and relocating each control.
My current forms and panels have set their size to 1900x1080, so they just extend out of the screen on the lower resolution.
I have played around with AutoScaleModes and AutoSize, but the best I could get were Scrollbars so that you at least navigate through the forms. Is such a thing as downscaling an application even possible (retaining dimensions/ relative sizes and positions of the controls)?
Thanks in advance for any inputs on this!
If your main form starts in a maximized mode, it will adjust its size automagically.
But (and this is a huge "but" according to your question): the inner controls won't be scaled as you would see on a smartphone. WinForm is not "vector based" as WPF. If you have a fully loaded form in 1920x1080, when the main form is sized down, the controls won't fit and you will get scrollbars.
So the answer is: No.
The solution is available.
Form.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi;
and
Make all control autosize = false.
make a suitable size of your wish.
The property you are looking for is called Dock, it's a property of the controls.

This basically tells the control how to fill the available space.
Creating a resolution independent application is not a simple logic. Everything in the window should be resize as per the selected resolution. Not only controls' size you have to change the font size also as per the changes. Here is the example how to create a resolution independent form using C# code. Another way is use DevExpress Tool. This tool provides Layout Countrol Container. You can place each control in separate layout item and assign the minimum and maximum size of control.
I am C++ programmer, and I am working on a migration project where I need to convert C++ code to C# and I have little knowledge on C#. Also, Clients want the application in .net 2.0
Issue:
When the screen resolution changes to low resolution, the form is adding a scroll bar to show all the controls in the screen. But, Client wants without any scroll bar such that all the controls should be visible.
Font applied to the controls should fit to the control dimension even if we change the resolution to high or low.
Any suggestions?
Use containers to house your controls. TableLayoutPanel would probably be a good choice. Set the TableLayoutPanels DockStyle to Fill. TableLayoutPanels only allow you to put one Control in each section, but Panels allow multiples so put a Panel in each section and set each Panels DockStyle to Fill. Arrange your controls in the panels and set each controls Anchor or DockStyle properties to keep them in location. Now, set your resolution to the lowest possible setting and build your form. If you follow the above steps, when you raise the resolution everything will be in the same relative location with the same relative size.
Why it works: Setting the tablelayoutpanels DockStyle to Fill makes it autosize with the parent form. Setting each panels DockStyle makes it autosize with the TableLayoutPanels sections. Anchoring/Docking controls inside the panels keeps the controls sizing and spacing relative to the panel.
typically in java if you have a layout manager of somesort, when you resize the page then the components in that panel will resize accordingly. I think my app is missing some sort of layout manager to control resizing as at the moment everything is just static
Is there a way to make it resize on the changing of the form size? say the user makes the page bigger, then the componenets adjust and so on.
Thanks
.NET has layout managers as well.
Personally, I prefer the TableLayoutPanel for my WinForms apps.
Once you layout the Table (using a combination of static/dynamic sized rows/columns) you add your child controls to the table cells. Once you add your controls, you can dock or anchor the controls to the cell so that they are automatically adjusted when the window is re-sized.
Two main options:
Anchoring. Set your control to "anchor" to the sides of your form. This means that if the form resizes, the control will stay a constant distance from that side. So, if you anchor Top, Left and Right, then your control will stay in the same position, but resize horizontally with the width of the form. Play with it. It'll be obvious.
Docking. Set your control to "dock" to a side of the form, or the center. This is usually done with containers, and it will make the widget take up that entire portion of the form no matter how large it gets.
In Windows Forms you make use of the Control.Anchor property, which will cause the control to adjust accordingly when the window resizes.
To do this with windows forms you use the Anchor and Dock properties of the control
