How To Resize Controls When Form Changes Size In C# | Windows Forms | Visual Studio 2022 

i find a mistake in method resizeControl not int newX = (int)(r.Width * xRatio); int newY = (int)(r.Height * yRatio); true its: int newX = (int)(r.Location.X * xRatio); int newY = (int)(r.Location.Y * yRatio);

high quality content, ty! Your channel deserves to be so much bigger, keep it up.

Would you mind remaking this tutorial with a bunch of controls of many different types. I tried it your way, precisely, but regardless of what I set the anchor property of a control to inside visual studio, the second the form got smaller than it’s initial size all the controls decided to throw a party on top of one another in the upper left hand corner. Even if the distance between the bottom of the form and the controls that were set to anchor at the bottom prior to resizing vs the distance between the bottom of the form and the bottom of the control set to anchor at the bottom were not even *remotely* similar. You’d think the y coordinate of the controls set to anchor at the bottom would be less after resizing than they were prior, right? Nope. Bigger. The (maybe) good news is I have managed (I think) to eliminate the need all the rectangle variables in the form load and the partial class except for the form size. I just declared/initialize the form size variable in the class and in the load method the way you said. Then I eliminated the resize method and put all the dirty work in the in form resize method. Like this: Form1_Resize(//the normal stuff here) { Int xRatio= this.width/ o.f.s.Width; //tried it as a float but still don’t work your way) int yRatio = this. Height/ o.f.s.height; Int initialX; Int initialY; int initialWidth; Int initialHeight; foreach(Control con in panel1.controls) { Con.width = initialWidth; Con.height= initialHeight; Con.Location.x = initialX; Con.Location.y = initialY; Con.Location = new Point(initialX*xRatio, initialY * yRatio); Con.Size = new Size(initialWidth * xRatio, initialHeight* yRatio); } } PS: before anyone tells me that I can’t blame him for my own code not working….I did it exactly the way he said in the video originally. The behavior of the controls were exactly the same as it is rn, at least when it comes to shrinking the form. At least this way I don’t have like a gazillion extra rectangle variables.

Thank you so much tremendous video I spent so long looking how to do this so strange windows forms don’t have it built in already

Thanks for this. I'm complete new to C#. I've dipped my toe into C# because I want to create a "launcher" window on startup where a user picks one of 2 applications. (for a home arcade setup, which won't have a keyboard or mouse - only a joystick/buttons which pass key presses) I've managed to create a static sized form window that works with both buttons. But now I want to see if I can make the window maximized and resize the buttons properly, regardless of the actual screen resolution. In my scenario, the window will not be resizable, but simply always maximized. Hopefully your tips here will guide me down that road.

it doesn't work!! control vanish if form resized!!

This is extremely helpful man. Thank you for the thorough walkthrough!!

The reason why we use rectangle is because all controls are some sort of rectangle! Nice.

thank you I've spent ages trying to find this. definetly subbing

Thank you for making this creative idea ! Not to say anything bad about this idea but I guess it is not really optimal and usable in reality ? Because I see people only make windowed mode or full-screen mode for apps. I also think this code really consumes memories as it literally render everything visible before our eyes in real time, and let's say we don't have just 1 button but thousand of actions at the moment. How do you think about my opinion ? Still, thanks for sharing this :D

Font size should also be resized accordingly ?

Very helpful video, but I got a problem, my controls will jump to another location when I first resize my form.

Great video, I am creating a borderless form application which has forms loaded within a panel on the mainform, I wish to drag and drop between 2 different screen resolutions, however the control is not resizing with the form when dragged from the smaller on to the larger one. If i close the childform on the larger screen and reopen it, it is correct size.

Thank you so much Shaun. This video is very helpful.

Is it possible to select all elements in my application without having to write a 'buttonOriginalRectangle' for each element? I have 7 buttons, 1 picture box, a menu strip, and a label, and I want them to dynamically resize perfectly.

Thanks it also works on visual studio 2019 cause 2019 and 2022 don't have much difference also good content keep it up! But how do I use it for multiple buttons and object? Or even for all object in the form?

Does this work with TextBoxes and MenuStrips? It does not seem to be working. The text box just disappears and nothing happens to the MenuStrip.

Thanks for video. But I have problem and I cannot find solution. It works on computer where is visual studio. When I copy release build to the other computer where is not VS, the resize function causes the controls to not be displayed at all. If I comment resize function controls are showen. Do you have some idea?

High quality tutorial really liked it. My button only becomes visible after I resize the form and not when it initially loads why is this?

Now the form controls aren't even visible on the screen lol

Great explanation...could you create a video to increase the text size which is inside the button.

okay. but o. s.s that allow real time proportional sizing of all objects in a window. all objects shrink. everything in the window remains. just that reducing the size of a window makes the complete image shrink. guess it's hard to articulate.

Good job Shaun!

How would I use this method to resize the text on the button or a textBox?

Only works if you have one control. If you add controls they all go to the same position or stack on top of each other. This is more confusing than leaving it and just losing it when resizing.

Thanks for the video. I am so close to actually making it work for me and yet so far. For some odd reason my "button1" cannot be called in my "resizeControl" function because it is of class Forms::button(Forms.button for C#) instead of Forms::Control (Forms.Control for C#) and it messes up my project. I would just copy ur entire project but I am trying to implement it on c++...

I think line 34 and 35 maybe need to be edited, don't they? They should be changed to int newX = (int)(r.X * xRatio); int newY = (int)(r.Y * yRatio);

Thanks very helpful video

Unfortunately, your solution is also not true scaling. It is a good dirty method to fix a one off issue, but lacks text scaling and alignment anchoring. Thanks anyways.

Could you please show me how to do multiple buttons instead of just one???

Is picturebox possible? There are no autosize and mode items in the properties window

Greate Work thank you so much

Thank you

I like the video at all

No tutorial seems to help me with what i need. I want to make the form scale according to the resolution like you resize a image in photoshop/paint.

I tried this with my picture box. I'm sure I've got everything correctly but every time I resize my window it just dissapears. Any ideas why? Edit: got it all sorted. Found solution in comments.

I am using .net frame work in windows forms app but my form won't load

there must be a better way of doing this, no way i need to add code for each form? what about just using tablelayoutpanels?

Can I get help to do this in c++?

OMG THIS GUY SPEAKS NORMAL ENGLISH HOLY SHIT

It works in uwp?

EDITED? orignal code has bug ^ ^; newx newy is not correct

thats a lot of coding for one button but what if you have a lot of components in the UI

Thank you from Russian

int newX = (int)(r.X * xRatio); int newY = (int)(r.Y * yRatio); In the video you don't update the locations correctly. You used the width and height.

Nice job, I get the concept, BUT no one has a form with one button. So this video does not really help much. ---sjt

It should be int newX = (int)(r.X * xRatio); int newY = (int)(r.Y * yRatio);

🙏🌹

not working

autocomplete carried the whole video lol

text stays the same size… half-job

speak less buddy
