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
See this for a guide on how to use them

I have a windows form application.I set background image for this form and BackgroundImagelayout property is Stretch.When I put a button on the specified place on image and run this app,place moving and commix my design
What should I do? Help me please
This should work for you
Define the size of the form
make the form not resizable
make the image same size of the form
fix the background, not stretch
set the anchor property of objects to top left
If you are trying to make a layout that can size, you will need to break up your graphical elements into multiple parts, and then use layout controls with parts of the background image that can reposition as the form resizes.
For example, your form can have a tiled pattern, stretched gradient, or whatever you may have. Then, you can have a TableLayoutPanel that contains evenly spaced buttons and fields. The panel can have a background image of its own. The same goes for the other layout containers. You can nest the containers if the design requires it.
Then, you can set the various anchors and docking to keep the design uniform.
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.
If you imagine a win form with a line drawn vertically down the middle. On the left i have a graph, and when you click the graph certain forms open on the right in an mdi type panel.
I am trying to figure out how to logically get this to look like a proper application should but am failing!
The whole form loads in a maximised view. I first set the panel width to 0 then when i add a form i check if the panels width is less than the forms, if it is then change the panels width to that of the forms.
This doesn't look great tho tbh, resizing makes strange things happen and i see a lot of grey. Does anyone have any ideas?
Use a SplitContainer on your main form. Ensure it's Dock property is set to Fill
Put your graph stuff on the left panel, and your other stuff on the right side.
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.
I have one form which size is (325,325) and on which one browser is there and the size of the browser is (321,298) means browser is in the middle of the form.And I want to maintain the size of the browser when form is resized like there should be the same difference of the size between form and browser as it was before resized.
Like the previous answers stated, you should Anchor the control.
You should set the Anchor property to Top, Left, Right, Bottom to let the browser grow/shrink when the form is resized, but maintaining the margins.
You should Anchor the control on the form.
Have a look at

Anchoring a control to its parent
ensures that the anchored edges remain
in the same position relative to the
edges of the parent container when the
parent container is resized.
Setting the WebBrowser's Dock property to Fill is the correct answer here. This completely eliminates the possibility that you'll have layout problems when you run your program on a machine that has a different system font size or a different video adapter DPI setting.
If you need room for some kind of gadget or toolbar, be sure to dock it as well (usually Top). Use Format + Order if the browser ends up underneath the gadget.
Use the control's Anchor property to anchor it to all 4 edges of the form. The control will automatically change it's size when the parent form resizes then.
The MSDN article explains the basics. Google finds quite a few interesting links as well.
