When I want to maximize my form I have always to unenable maximize button, because when I want to maximize it, the controls don't feet the new screen size so that they are always at top-left side after maximizing. My QUESTION is: how to maximize the form so it fit the new size??
No actual answer. I have understand the tableLayoutPanel now. It is very beautiful
Play with the .Anchor property of the controls so they move where they are supposed to move when you maximize.
The best solution I found so far is using TableLayoutPanel. You can use nested TableLayoutPanels inside each other to organize your UI. For each UI component, you have to set property Dock to Fill (including TableLayoutPanels).
That way, you will have robust UI configuring itself automatically when size changes.

What would be the best way to make a WinForms application fully scalable, for example when the Form resizes?
In WPF i would use something like a Viewbox and/or a UniformGrid, but something like this doesn't exists in WinForms.
Is there an easier (and maybe faster) way to rescale controls on a from after resizing it, instead of resizing them all by calculating their new Size/Location etc.?
Thanks in advance
In Windows Forms, you use the Anchor and Dock properties for each control.
Here's an article about using them: http://www.techrepublic.com/article/manage-winform-controls-using-the-anchor-and-dock-properties/
You should also look at FlowLayoutPanel and TableLayoutPanel
you can use anchor and dock, depending on your need:
Anchor - the edges of the container to which a control is bound and determines how a control is resized with its parent.
Dock - which control borders are docked to its parent control and determines how a control is resized with its parent.
for further read: Dock and Anchor
Have a look at the Anchor property found on pretty much any control. This allows you to lock a control to any (or all) of the four borders of a window.
Once one distance is anchored (e.g. Top or Right), the control will always try to keep that distance, no matter how you resize your window.
For example, you'd set Anchor to Bottom and Right for a button that is supposed to always stay in the bottom right corner of a window. A text box, that should always fill the window from left to right would use Left and Right.
Similar things can be achieved utilizing Dock, but a docked control will always try to fill as much space as possible (there are different strategies available, like "fill everything from here and upwards) based on its container. Depending on your use case, this can however be a lot harder to control (and I usually only use it if I want a single control to fill a full window, e.g. a TextBox).
If you need more complex alignment, like widths scaled on some kind of ratio (e.g. 30%), then there are several different containers available.
I'm trying to write a simple GUI that renders a number of images using the Graphics' object primitives. What I want to have is a series of areas that I can paint to in isolation of the other areas, so that each painting "canvas" has it's own origin within the global coordinate frame of the top-level form.
So far I have tried adding several panels to a FlowLayoutPanel. However, they seem to be getting placed one on top of the other, as only one onPaint method is being called. I can override the Form's onPaint to invalidate the other panels, which are then painted, but not displayed.
Besides setting the sizes, and initialising the FlowLayoutPanel, is there something I'm missing? Is there a better way of doing this?

based on the names of your classes, it looks like you are designing a game ... maybe you want to take a look at Microsofts XNA framework?
however, the problem with the code you provided is, your layoutPanel is not sized correctly, therefore its child-controls are not visible on the main form... since painting is only done for visible items ... there is no painting for most of your FloorDrawPanels ...
try changing the size of your layoutPanel or setting its dock mode to fill
You don't set the size of the FlowLayoutPanel. It will default to 200 x 100 with a Margin of 3. You fill it with controls that are 100 x 100. Given the margin, only one of those controls can ever be visible at the same time. It is therefore no surprise that you only ever get one paint event, Windows only asks visible controls to paint themselves.
Not quite sure what was intended, start by making the FLP bigger. And set its AutoScroll property to true so that the user can scroll the other controls into view. Using the designer would have been a quick way to find this out btw.
I'm new to Windows Forms in Visual Studio, and I am wondering how to automaticly resize controls to the window size.
Say, I have 2 controls in a panel, a List Box and a Button. I want the button to dock to the bottom, and I want the List Box to fit the rest of the space. when the window resizes, the button should be at the bottom (as expected with docking), and the list box should stretch down to the button.
Is there a way to do this without any code?
Thanks.
Dock is pretty easy to use, but I recommend using the Anchor properties instead. Resize your form to a reasonable size in the Designer. Then, place your controls to look the way you want. Then, decide which controls should resize with the form and set the Anchor property as follows:
If you want the control to resize with the form in width, set the Right anchor.
If you want to resize height, set the Bottom anchor.
If you want the control to stay right when the form resizes, unset the Left anchor.
If you want the control to stay bottom when the form resizes, unset the Top anchor.
The problem I have with Docks is that they sometimes act funny when controls are not declared in a specific order, and to get the effect you want, sometimes you have to create extraneous panels just to hold controls.
It really gets messy when you want to maintain the aspect ratio of each control. One way, which is not really up to the mark if you want to get into fixing the details, is to use TableLayoutPanel and use Dock and Anchor wisely to achieve what you want.
Use the dock and fill options on the controls. Look under properties for each object, and containers if they are in any.
You can use SplitContainer
Google for examples. Here is one
Try setting your ListBox's Dock property to Fill.
You'll need to watch for one thing though: by default the ListBox will size itself to display whole list items. If you resize the control so that it displays a partial item it will adjust itself so it will display a complete item. This can make the control appear to lose its 'Dock'ing behavior. The solution for this is to set the ListBox's IntegralHeight property to false, which specifies that the control not resize itself to fit complete items.
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

iam having an MDI form,in which i placed a form.i have some issues while resizing
how to set the maximum for the the mdichild so that it cannot be resized to the entire
container if i selects maximize
is it possible to put anything apart from a form inside the container( i am using a third
party component dotnetmagic,i want to create a content using it and like to place it in the
mdicontainer)
Thnx in advance
Set the normal MaximumSize/MinimumSize property of the MDIChild Form, or see http://support.microsoft.com/default.aspx?scid=kb;en-us;327824 if it doesn't work.
No. Consider using WPF and Canvas, if you want to create a custom drawing environment.
