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...

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 have a form which have so many controls in an old winForms App
the client said he's using low screen resolution to easily manage this form
and now he want the controls and there font size to be big regardless of the screen resolution
if it's not an easy process is there any thing i can start with ?
Put this in the form's OnLoad override or Load event handler:
this.Font = new Font(this.Font.FontFamily, 1.25f * this.Font.Size);
Which takes advantage of the built-in autoscaling as configured by the AutoScaleMode property. Whether that will keep the layout intact is a unguessable, you'll have to try.
Your customer can do this too by increasing the video adapter's DPI setting. On Vista and up, going past 125% (120 dpi) triggers compatible DPI scaling. Which makes the OS lie about the DPI setting and produces a larger window through bitmap scaling. Makes it fuzzy but big enough to be usable.
You can change the style for each of the controls or you can create a style class and change your controls to consume it as shown in the following link: http://www.codeproject.com/KB/miscctrl/WinFormStyleSheet.aspx
Most winforms controls that display text have a FontHeight property which you can modify in order to set the permanent font height for that particular element. This is the most flexible solution where you can control which elements get the larger font treatment.
I have created some controls in C#, and am successfully using them. However, on user PC's with custom set (font) DPI to let's say 125 % or even 150 % -- My controls inherit the new scale, and do not display correctly.
I would like to know how to disable my control from inheriting this scale.
I know this is not the answer you would be looking for. But consider why people have their system set the way it is. it may be a vision problem or just their perference. Yes, handling the scaling diplay can be a pain, but that is better then a user disregarding your product because they can't read/use it.
If you're building your own application, you can set the AutoScaleMode property of a Form to "None" to disable the automatic resizing of the Form's font based on the system DPI setting.
If you're simply building a control that others will integrate into their own forms, you'll want to override the Font property of the control and force it to your pre-determined hardcoded value.
Also note that, as others have said, you don't want to do this -- the user has adjusted their system DPI for a reason, and overriding their choice is likely only going to make your control unusable to them. If the problem is merely that your control isn't scaling correctly when the system DPI is changed, make use of Winform's AutoSize capabilities and use layout panels that will automatically adjust as the size of things change, such as TableLayoutPanel (with AutoSize set appropriately on rows and columns) or FlowLayoutPanel.
I have a WinForm,when the its size is 700x700,when I change the screen resolution of the system from 1366x768 to other(like 800x600),only part of the window is visible.How can I make it fully visible? what property of the form i have to change?
I would say would say you want to adjust your Form.Size and Form.Location to fit within the Screen.GetWorkingArea(). You will want to do that when the event Microsoft.Win32.SystemEvents.DisplaySettingsChanged is fired. As in this answer.
You will want to adjust the Bounds property of your form. Screen.PrimaryScreen can support you to get the new right size.
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.
