Windows Application resizing

When it concern with windows application it all depents on design,
1) Use table layout panel make it Doce = Fill for the page
2) Define rows and columns as per your control needs
3) Put controls in cell and apply Anchor property to Top, Left (Or as per your setting)


===============
Just need to say it all depends upon Dock and Enchor property..!!

There are some third party products that provide this as well.
How this[^] one is not free.

We may be talking about three different things here:

1. handling a change in screen resolution: when your application is running: your application is not going to have "focus," and the standard EventHandlers, like SizeChanged (in WinForms) are not going to be called.

If you really want your running app to detect a change in screen resolution: the answers you need are here:[^].

It's hard for me to imagine a situation where screen resolution changes while an application is running (?) If you have to handle this (rare ?) case, I wonder what requires you to code for this.

2. dealing with scaling and positioning of Form elements when the Form size is changed (while, obviously, your application is running).

The article that Johnny J. referred you to (deservedly upvoted) should give you some strong clues about how to roll-your-own re-sizing and re-positioning, using Panels.

I have not had the bad experience using Dock, and Anchor, that the author of the article that Johnny J. linked to describes with such "horror."

3. detecting when your application starts the aspect ratio of the current display, and, if your layout is based on a different aspect ratio, adjusting all the controls ?

Of course a big reason many people changed to WPF is: you get automatic scaling for "free." On the other hand, since I don't use WPF, I would be interested to know if there is aspect/ratio correction if you change screen resolution while running a WPF application: I think I'll post a question on this on the WPF forum out of curiousity, but keep in mind that WPF is "history."

No way I'll pay US $200 for either of the third-party controls for WinForms described here :)

good luck, Bill

Docking can help of course. Just look in the Properties of the control how you want to be resolution independent and set the docking, then the control automatically resizes too when the form does.
For more please see this CP article;

Also have look on similar discussions, you will get surely needful from them:

Have a utility class ---- in the utility class based on resolution of your screen re size the controls. call the function of the utility class in form load () . the utility class method takes form instance as parameter.
