I have a custom styled transparent window and i've seen a lot of issues handling min/max/resize behavior when you use transparency and "WindowStyle=None".
When I tell my window to change it's windowstate to maximized it doesn't get it right so I want to override the logic there. It gets the width right but the height is all messed up and it doesn't know to add padding to account for a outerglow effect.
Without using win32 functions is there a SOMEWHAT EASY way for me to determine the "max viewport" or "max bounds" of the display that the application is running on top of? I think the short answer to this question is probably no but I figured I would ask anyways. I have my min/max width and height set up for the application and I figured if there was some function I could call to bring me back a x/y max bound then I could just set the window height and width to those values after I subtract the padding. My intention is to have supported resolution from 1024x768 - 1920x1080 so that this application can be displayed multiple places without reconfiguration.
Take a look at the Screen.PrimaryScreen Property. It has a method called GetWorkingArea which I think is what you want.
If there is more than one display, then there are methods to enumerate through the displays and find out which display the application is on.

I have a problem and I couldn't find the answer anywhere on the internet. I am working on a project which its forms should be fixedsingle borderstyle. I don't want anyone to maximize or minimize the forms. So the real question is that I have two monitors and I'm working on the bigger one. When I start the program and slide the form to the smaller monitor, it looks exactly the same heigth and width. But I want the form to look smaller as the screen gets small or to look bigger if the screen gets bigger. Can you please help me?
You need to specify the Form.MinimumSize and Form.MaximumSize properties according to your needs. If you want to adjust the form dynamically at run time, you can hook the Form.Move event and set those properties relative to the screen's resolution minus the space used by the taskbar using Screen.WorkingArea. For a better user experience if the form is smaller than the screen size, I recommend disabling the maximize form button by setting Form.MaximizeBox to false.
I know this is an "already heard" problem: I have searched a lot but I did not find anything that cleared my mind.
I am developing a c# application with a GUI containing some controls like buttons (made with images) and text.
I developed it setting the main form size to 800x600 but now I need the application to work also on a 1920x1080 screen.
Two problems:
If I position a button near the top-right corner of the main form and set AnchorStyles to Top-Right, when I switch to the big screen, the button is (in proportion) much more close to top-left corner than in the little screen (because the anchor keeps the distance from the border). Is there a way to set a proportional distance from the border?
How can I scale the dimensions of the controls proportionally to the screen size? Shall I use AutoScaleMode like suggested here?
There is a way to add a capability to a form at design time - the ToolTip control does it, that makes properties available to every control on a form. These are called "Extender Providers"
http://msdn.microsoft.com/en-us/library/ms171836
You would want to look at the controls, and cache their sizes and fonts at design time, and the size of the form.
The provider would hang off the form.SizeChanged event at run time. When the size changes, you use the new and original (design time) sizes of the form to calculate and X and Y ratio. You then go through each control and use it's design time size and the ratios to determine its new size and font size. This can get flaky if you allow the user to select sizes that are not the same aspect ratio as your original.
Anyway, that is how it was done in Delphi, and everyone knows if you can do it in Delphi, you can do it in C# :)
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.
http://msdn.microsoft.com/en-us/library/system.windows.forms.control.dock(v=vs.110).aspx
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.
Basicaly i am trying to set the window size automatically to the minimum size before the scroll bar appears, logically I am thinking that if I set the size of the window to this size and all the components should be shown no problem, I tried a couple of the answers answering the other questions but that didn't work, minimum size is 0.
When I start up my application it doesn't show the full content, i am using a telerik report viewer(if anyone knows what it is) in a radform, but don't mind the names, the report viewer and radform are just extensions of the known winform and component so the same rules apply.
The thing is when I show the window it won't show the full component, it's mostly the horizontal scrollbar I need to remove by resizing the window.
I tried outputing the autoscrollminize property on both the form and the component but they are both 0,0 however if the scrollbar appears and disappears when I resize the window manually there should be a property/value somewhere I could use to set the windowsize from the start.
technical info:
the component is already docked
if I undock the reportviewer component the scrollbar appears inside this component so the key is to figure out when the vertical scrollbar will appear depending on the data in this component
I already tried
setting the autosize property to true for the window and setting the size to 10,10
finding minimum size/AutoScrollMinSize
Setting the size to preferred size(when I do this the window takes on the absolute smallest possible size showing only the title bar.)
the form minimus size is the minimum size that YOU set on the form, it's not a minimum value calculated for you.
You need to calculate/find-out the space needed by your controls, and then you'll have a value to set in the form height/width.
For calculating the space needed by your controls, it's up to you: maybe rows numbers multiplied by row height + header/footer height? or something like that.
You can even do some different research: if there are scrollbar, somewhere there is already the value you need, you only need to find it out.
For doing this kind of research there is a tiny free tool that is very useful
Hawkeye - The .Net Runtime Object Editor - http://hawkeye.codeplex.com/
It works like a property grid, but you can hook it to running .net programs, and it show you everything (properties value, private field value, object reference...) so you can try to dig in the scrollbars object to see if you can find out your height/width value.
Whenever I try to increase the form width in the properties box of VS 2008 it just resets my change back to 1300. It lets me lower the width, but not increase over 1300. How can I fix this? I have a datagrid in the form which has a width over 1300.
Windows in Windows cannot be larger than your screen resolution.
In code (eg, in the form's constructor), you can set any width you want, and it will be restricted by the end-user's screen resolution at runtime.
Your form should not need to be so big; consider redesigning your UI and/or using scrollbars.
you should check the Form.MaximumSize.Width property
Form.MaximumSize Property
so if you need to increase one of the two or both make sure that MaximumSize is also updated to your new values.
Edit: SLaks is correct that you cannot have the form bigger than the monitor anyway...
