Resize 4 picture boxes when form is resized

I am implementing a winform application in c# so that it contains four picture boxes and some control buttons in one corner.
My main problem is that I cannot achieve the behaviour shown in the picture. The idea is to automatically resize the picture boxes when the form is resized. The area of the control panel should stay the same and only the area containing the boxes should be resized accordingly.
I have been playing with anchor and dock properties but I dont get the desire output.
Anyone could give me a hint?
Thanks and kind regards,

So, let's say you have the following picture boxes:
pictureBox1 | pictureBox2 | panel
------------|------------
pictureBox3 | pictureBox4
Then the following should do the trick:
set the forms Resize event to this eventhandler:
private void Form1_Resize(object sender, EventArgs e)
{
int spaceBetweenPictures = 19;
int widthToFill = (this.Width - 40 - panel.Width) - spaceBetweenPictures;
int heightToFill = this.Height - 80;
pictureBox1.Width = widthToFill / 2;
pictureBox1.Height = heightToFill / 2;
// Setting the sizes of all the three pictureboxes to the sizes of the first one.
pictureBox2.Width = pictureBox1.Width;
pictureBox2.Height = pictureBox1.Height;
pictureBox3.Width = pictureBox1.Width;
pictureBox3.Height = pictureBox1.Height;
pictureBox4.Width = pictureBox1.Width;
pictureBox4.Height = pictureBox1.Height;
// Setting the positions:
pictureBox2.Location = new Point(pictureBox1.Width + spaceBetweenPictures, pictureBox1.Location.Y);
pictureBox3.Location = new Point(pictureBox1.Location.X, pictureBox1.Height + spaceBetweenPictures);
pictureBox4.Location = new Point(pictureBox2.Location.X, pictureBox3.Location.Y);
}
Of course you should modify the magic numbers in this code (19, 40, 80) accordingly, to suit your program (that depends a lot on whether you use border on your form or not).
UPDATE:
If you want your pictureboxes square shaped then just ignore the heightToFill variable and use widthToFill instead when setting the Height of pictureBox1. Or set:
pictureBox1.Height = pictureBox.Width;
And I also forgot to mention that the panel of course should be aligned Top, Right. So set the panel's Anchor property to:
AnchorStyles.Top | AnchorStyles.Right;

Are four image boxes supposed to support resizing at runtime (allowing end user to resize)? if not then following will give you desired result.
1 TableLayoutPanel with 2 rows and two columns. Set the initial size to fill the desired area, set the anchor to all four directions.
Add 4 picture boxes to 4 cells and set Dock to Fill for all Picture Boxes.
Add a panel to the right side of form, and make it fit to cover your controls area. Set the anchor Top, Bottom, Right.

Relocating panels gets mixed up WinForms

I am creating an application using C# and WinForms. I have three panels. Two of them are fairly large and are currently positioned side by side. I am trying to implement a feature for users who have smaller screens or wish to have the form as a smaller size. I am relocating the right panel underneath the middle one and re-centering them in the form.
The issue that I have though is when the user scrolls down and re-sizes the form again the two middle panels (the big ones) move lower in the form leaving a chunk of blank space at the top.
My code is fairly simple
namespace ResizeCheck
{
public partial class Form1 : Form
{
Point originalLeft, originalRight;
bool flag = false;
public Form1()
{
InitializeComponent();
originalLeft = leftInnerPanel.Location;
originalRight = rightInnerPanel.Location;
}
private void vertical()//move the right panel under the left one
{
leftInnerPanel.Location = new Point(this.Width / 2 - leftInnerPanel.Width / 2, 5);
if (leftInnerPanel.Location.X <= buttonPanel.Location.X + buttonPanel.Width)
{
leftInnerPanel.Location = new Point(buttonPanel.Location.X + buttonPanel.Width, leftInnerPanel.Location.Y);
}
rightInnerPanel.Location = new Point(leftInnerPanel.Location.X, leftInnerPanel.Height + 10);
MessageBox.Show("inside vertical " + leftInnerPanel.Location.Y);
}
private void horizontal()//relocate to their original horizontal position
{
leftInnerPanel.Location = new Point(buttonPanel.Location.X + buttonPanel.Width + 10, 5);
if (leftInnerPanel.Location.X <= buttonPanel.Location.X + buttonPanel.Width)
{
leftInnerPanel.Location = new Point(buttonPanel.Location.X + buttonPanel.Width, leftInnerPanel.Location.Y);
}
rightInnerPanel.Location = new Point(leftInnerPanel.Location.X + leftInnerPanel.Width + 20, 5);
MessageBox.Show("inside horizontal " + leftInnerPanel.Location.Y);
}
private void Form1_SizeChanged(object sender, EventArgs e)//handler for when the form is resized by the user
{
if ((leftInnerPanel.Width + rightInnerPanel.Width + buttonPanel.Width) >= this.Width)
{
vertical();
//flag = true;
}
else if ((leftInnerPanel.Width + rightInnerPanel.Width + buttonPanel.Width) + 50 < this.Width)
{
horizontal();
//flag = false;
}
}
}
}
My designer code is also fairly simple.

}
}

You are not accounting for how much the form has scrolled, you are simply plopping the panel at the top of the visible client area.
Change your Vertical() method thusly:
private void vertical()
{
leftInnerPanel.Location = new Point(this.Width / 2 - leftInnerPanel.Width / 2, 5 - VerticalScroll.Value);
if (leftInnerPanel.Location.X <= buttonPanel.Location.X + buttonPanel.Width)
leftInnerPanel.Location = new Point(buttonPanel.Location.X + buttonPanel.Width, leftInnerPanel.Location.Y);
rightInnerPanel.Location = new Point(leftInnerPanel.Location.X, leftInnerPanel.Bottom + 10);
}
Two points to note:
1) use of the VerticalScroll member.
2) use of Bottom instead of Height (and Right instead of Width in the Horizontal() method).

In vertical()
since you are not adjusting the Y of leftInnerPanel, we can straightaway use the buttonPanel.Top
leftInnerPanel.Location = new Point(this.Width / 2 - leftInnerPanel.Width / 2, buttonPanel.Top);
Secondly,
//rightInnerPanel.Location = new Point(leftInnerPanel.Location.X, leftInnerPanel.Height + 10);
rightInnerPanel.Location = new Point(leftInnerPanel.Location.X, leftInnerPanel.Bottom + 10);

C# : How to add both scrollbars in a PictureBox contained in a SplitContainer Panel

I've found a similar question, but the answer only helps making one of the scrollbars appear.
My form has a SplitContainer. In one of its panels (Panel2) there is a PictureBox with an image i want to show.
What i need is to find a way to make both vertical and horizontal scrollbars appear when the image exceeds the panel's size.
I already set AutoScroll to true, and I've seen it's necessary to set Anchor at left for one of the scrollbars to appear, and at Top for the other one, but i need both of them.
Thanks in advance.

make sure your SplitContainer.Panel in which you embedded your PictureBox
has AutoScroll property set to True
and your PictureBox has SizeMode property set to 'AutoSize' (PictureBoxSizeMode.AutoSize).
Hope I helped you :)

WinForm Bottom Margin Property Doesn't Do Anything

I am new to WinForms, and I am very used to styling in CSS, so maybe I am not looking at WinForm's Bottom Margin property correctly, but, no matter what element I set an arbitrarily large bottom-margin number to, it seems to have no effect, at all.
What I want is to extend the design of the form to below the initial viewable window (vertical-scroll bar shows up just fine), and set a bottom-margin to these elements so that the very bottom of the element isn't flush with the very bottom of the window (a little space would be nice).
I have tried this on several elements just to see if it was only the one element (or the fact that it was out of the initial visible part of the window) that was giving me problems, but I can't seem to get any effect out of the margin property at all.
Looking here: http://msdn.microsoft.com/en-us/library/ms229627.aspx It seems that this is, indeed, what the margin property should do. Also, I can't find any padding within the GUI controls for any element.
As it stands, I am mostly only coding C# for the event handlers, until I get a better grasp of where Visual Studio puts everything within the two partial classes (and the other .cs files).
If it helps, here is the code for the designer file:

------------------------------------------UPDATE-------------------------------------------
The element I have set the bottom margin property to within the code above is simply, richTextBox1.
Also, I did find a Padding element to the main form element, but sadly, this doesn't push other elements away from its edges either :(
What do these properties do (margin, padding)?

The Margin property is used by the automatic layout feature built into Winforms. But it does require that you allow the container to grow so it can provide the requested margin. So you must set the form's AutoSize property to True.
Combining AutoSize and AutoScroll is possible, you can set the MaximumSize property to prevent it from growing too much. The scrollbar automatically appears when the layout calculation produces a layout that exceeds the MaximumSize. The default maximum size is the Screen.WorkingArea on which the form is displayed, usually good enough.

keep button position on panel resize

I've been messing around with something that should be simple.
I've moved jobs and trying to get some of the basic tools I have used before, but of course I don't have the old source to look at.
We had extended panel to have some standard properties and functions (save, close, save and close).
But I can't get the buttons to be positioned correctly on a resize. I put this ExtPanel on a form but the buttons keep disappearing as I resize, or don't move as expected (frozen on bottom right).

Have you tried anchoring the button?
...I missed the anchoring code.
If you have a button in the lower right-hand corner that you want to stay in the lower right-hand corner when resizing the form, set it's anchor properties to Bottom, Right.
Update:
I loaded your code. You have a panel inside of ExtPanel. If you dock (Fill) that panel then you should be working fine by resizing ExtPanel.
