Has a program written in a notebook with a resolution of 1600x900, all the elements are placed normally, and the same program on a monitor with 1920x1080 scale from 125% windows are placed incorrectly. How on WinForms c# consider it and how to redraw?
You need to consider using the anchor and Dock properties this is how you position your controls on the form and control their positions in various scales
you can find here very useful article about using
anchoring and docking
By making use of anchors and docks then you should be able to create a WinForm which scales to any size monitor.
It would be helpful if you could edit your question and include the designer code so we can see what's happening.
In order to make the form resize as you want, You can use table layout panels to set your layout and then you can use the anchor property of the controls to set, where they should move when the form is resized.
The anchor property simply anchors the control to a location, for example if you anchor a text box to may be left, then on resize it will be at left. Or if you anchor it to say both left and right, if will expand in both directions. Just explore them and it should work fine for you.

How to run or adjust Windows application efficiently in any screen resolution in C# 4.0?
I have done it in 1600 x 1200 resolution but if I try in lower resolutions only some part of the forms are visible.
How to solve this problem? I have searched a lot and got to know about Anchor & Dock will be useful but also to came to know that these should be used from the beginning of designing but I have completed my application while this resolution is now causing the problem when I install the application in any system
The quick and dirty method of making sure your controls remain visible would be to place a Panel on the form, set Dock = Fill and AutoScroll = True, then place every other control in your form inside it. Your controls won't get cut off, but your program won't win any awards for asthetics. If the program is brand new, that's really not the way you want to start things off.
You could redesign it to make use of Anchors and Docking, as you mentioned. You could also place items such as a row of Button controls or a series of TextBox controls in a FlowLayoutPanel, which will take care of repositioning them as you resize the form.
But if adjusting for screen resolutions is important to you, a better way would have been to use WPF from the start. Controls are automatically resized and repositioned as needed, based on their container control.
The real question should be:
How do I want the controls to resize themselves with their parent?
The answer is that you need to specify anchors. Anchors are used to tell your controls how they should react on resize, and what the concerns should be.
Lets say you have a form with two [Cancel] and [OK] buttons. They are usually seen fit at the bottom right of your window. But the default Anchor property is set to Top, Left, so on your form's resize, they stick to the Top, Left corner where they belong according to the default settings. This won't be any trouble if your maximize your form, thus you'll have your button probably in the middle of the screen. But at least, you will see every controls adequately.
But what if resize your form smaller and smaller? Do you still want them to stick at the Top, Left, or Bottom, Right would be more useful? My guess is that you should set the Anchor property to Bottom, Right, for those two.
This might come in handy to have different Anchor property settings depending on how you want your control to react to your form resize. Let's take three TextBox controls aligned horizontally with each other. Perhaps your longer field will be your object Description property located on horizontal-center of your form. Then, when you risize, you have to think what would make more sense on resize. If it is to make it longer on resize in order to fill your form width with all your control, then perhaps you want the DescriptionTextBox to get wider and wider, and the contraray should also be true, on form's resize, you probably want this field to be resized smaller too. Then, to make this happen, you have to set the Anchor property to Left, Right, so that the edge of your DescriptionTextBox control remains at the same very distance of your form's edge at any time.
Another thing is of concern in case of resizing to smaller window, is its MinimumSize property. One shall agree that there is use to have a form of size 34x34 pixels. So, setting your MinimumSize property to a certain size which makes sens for the form to exist, you will avoid display glitches of controls getting one over another.
For more details on the Anchor property: Control.Anchor Property
For more details on the MinimumSize property: Control.MinimumSize Property
Kinda new in Microsoft visual C#. I have made a simple program. Everything is working perfectly fine, unfortunately the tricky part for me is i do not know how to layout my objects properly. I would like to copy the layout of the Microsoft visual C# interface, wherein the panels adjust to their predefined ratio and proportion whenever the main form is re-sized and the user may adjust the width and height of each panel. Any readings or code would be a lot of Help. THANKS A LOT!
You could do a number of things:
Allow automatic layout using something like a FlowLayoutPanel
Allow resizing of controls using a Splitter
Look at custom implementations to provide more advanced functionality Collapsible Splitter
Well follow these tutorial links to know about resizing in windows
using Dock and Anchor property. Along this the layout control will
help you to manage the layout - FlowLayoutPanel and
TableLayoutPanel, Panel, GroupBox etc.
Designing Resizable Windows Forms in Visual Studio .NET
Manage WinForm controls using the Anchor and Dock properties
This one is much better to understand.
For a simple start the anchor property is what you want. so for instance if you set all four anchors for that left hand control, and the parent window changes size it will will resize proportionally.
After that it starts getting complicated. Adding panels and then putting your controls inside them. Setting Dock to left, or top or fill. Grow and shink on scrollable controls. Splitter bars.
And last ditch handling resize events and calculating positions and sizes.
Sit down and have a think about what you want to happen, play around with minimum and maximum height and widths, ie no point in working out waht your form is going to look like when it's postage stamp sized...
PS Don't forget VS allows floating panels, and persists (well some times sort of) user choices in the layout, that's a bigger job.
Place a TableLayoutPanel as the base control, anchor it to all sides, define as many columns and rows as you like with "percentage" sizes.
Then place different sections of your form in different table cells. Properly dock your controls in each cell.
Can also use a split container above table if needed.
The ideal order should be like below
SplitContainer
TableLayoutPanel
Panel
Controls
When I expand the window, the textbox contained in it is not expanded. Can I expand it automatically when I expand whole app?

The Anchor property in the designer. Set it to Left,Right,Top,Bottom. This will cause the size of the text box to be linked to the size of its parent control.
Anchor and Dock Properties
These two properties are especially useful when you are designing your form. Ensuring that a window doesn't become a mess to look at if the user decides to resize the window is far from trivial, and numerous lines of code have been written to achieve this. Many programs solve the problem by simply disallowing the window from being resized, which is clearly the easiest way around the problem, but not the best. The Anchor and Dock properties that have been introduced with .NET lets you solve this problem without writing a single line of code.
The Anchor property is used to to specify how the control behaves when a user resizes the window. You can specify if the control should resize itself, anchoring itself in proportion to its own edges, or stay the same size, anchoring its position relative to the window's edges.
The Dock property is related to the Anchor property. You can use it to specify that a control should dock to an edge of its container. If a user resizes the window, the control will continue to be docked to the edge of the window. If, for instance, you specify that a control should dock with the bottom of its container, the control will resize itself to always occupy the bottom part of the screen, no matter how the window is resized. The control will not be resized in the process; it simply stays docked to the edge of the window.
try using the property "Dock", if you are working with winforms
I have a panel that has lots of labels and checkboxes. I want to grab all these controls and resize them?
How would I do this? Would this be like going through the panel for all the controls then resizing them?
Or do you think it would be better to re render the whole form again with the new sizes. However this would require me to do another request to the webservice to get the information.
I need to resize the controls because I want allow user to switch from portrait mode to landscape.
Use Dock, or for more precise control use the Anchor property. By setting Anchor to Left, Right, Top, Bottom the control will scale with the window. By setting Anchor to Right the control will move with the right border. By setting Anchor to Top and Bottom the control will scale vertically, but have a fixed width.
you can also use tablelayoutpanel and flowlayoutpanel controls.
For mobile, I think these controls are not available.
First of all, you should not just store the values from the web service in controls. They should be safely tucked away in one or more objects somewhere, to be easily accessed from your form.
I'm afraid you ahve to resize and/or change location of your controls depending on which mode you are in.

I'm developing an app for Windows Mobile 5.0 and above, with C# and .NET Compact Framework 2.0 SP2.
I have a WinForm with two panels inside (upperPanel and bottomPanel). I want that upperPanel always fill 2/3 of form's height, and bottomPanel fills 1/3 of form's height. Both panels will fill completly form's width.
I've used this:
upperPanel.Dock = Fill;
bottomPanel.Dock = Bottom;
But upperPanel fills the form completly.
How can I do this? I want, more o less, the same gui on differents form factors and on landscape or protrait mode.
Thank you.
What you need to do is to put the bottom panel on first and set its Dock property to Bottom. Then set the panel's height to be 1/3 of the form's height. Finally, add a second panel and set its Dock property to Fill. The key here is that you want to add the control that will fill the remaining area to be added last. Alternatively, you can play around with the Bring to Front and Send to Back commands in Visual Studio to get the designer to cooperate.
You may also need to hook the OnSizeChanged event for the form and re-set the height of the bottom panel to account for layout changes. It's been a little while since I did compact framework programming, so I'm not sure.
Right click on the upperPanel and select Bring To Front. However, I don't think this will give you the result you want. When you resize, the bottom panel will remain the same height, while the upper panel will stretch to fill the form.
Using your docking settings, with this code might do the trick:
protected override void OnSizeChanged(EventArgs e)
{
base.OnSizeChanged(e);
this.bottomPanel.Height = Convert.ToInt32((double)this.Height / 3.0);
}
Set both panels to "not anchored". That is: Remove Dock-Value and clear the Anchor property. Then, move the controls so they are sized the way you'd like them to be sized.
After that, upon resizing the form, they should resize relatively.
EDIT
Oops, just tried it and sure it doesn't work. I mixed this up with a solution that automatically keeps controls centered within the window...
Well, I'd guess you then have to create a handler for the form's Resize event and manually align the controls after the form has been resized.
Go to Tools, Other Windows, Document Outline. Find the two panels, and swap the order of them. The control that has DockStyle.Fill has to come first for it to be docked correctly. (or last.. never sure which one it is, but it is one of them :p)
This won't solve the always 1/3 and 2/3 issue though... cause the bottom panel will have a fixed height (unless I am mistaken). I think maybe the TableLayoutPanel supports this though...
Update: As noted in the comments, that panel doesn't exist in the compact framework. So, I suppose the easiest solution to this problem would then try to use the docking, but update the height of the bottom panel whenever the size of the form changes.
If you want this to work perfectly you'll need to add some code to the Resize event of the Form which then specifically works out the relative sizes and places the controls in the correct place after a resize.
If you're not worried about losing precision and the forms aren't going to move much you can avoid this by using some relatively smart anchoring. Essentially you're going to have to select a "grower" (the part of the form that gets bigger, the bigger the form gets). In this scenario I would probably anchor the top part to Top | Left | Right and the bottom part to Top | Left | Right | Bottom. This would mean that the lower part of the form will get bigger if the form is expanded. In most cases this is acceptable. If it isn't use the Resize event and some code.
The easiest way to do this is to nest panels. Just set up panels for top bottom and fill. Then use panels within those panels to do the same. The only issues I've had therein are datagrid resizing, which is always a pain anyway. in that case, you have to use some code to resize the datagrid control on the form resize event.
I would like to add a point to #jasonh answer.
For the panel that occupies 2/3 of the form, you will have to set the AutoScroll property of the panel to true.
This will enable the panel to display scroll when the control size exceed the visibility to the user and also ensure the visibility of the smaller panel which is 1/3 of the forms height.
You can get the required design by using nested panels along with few setting with Anchoring and Docking Properties.Follow the following steps:
1) Add the Form and put a Panel1 on it. Set its Dock Property as 'Fill' and ResizeMode as 'Grow&Shrink'.
2) Add Second panel2 and set its Dock Property to 'Bottom', Set the Height and set the Anchor property to 'Top,Left'.
3)Add Third panel and set its Dock Property to 'None', Set the Height and set the Anchor property to 'Top,Bottom,Left,Right'.
Save and Compile. Now all the panels Would maintain their relative Positioning With resizing.
