I've an interface where user selects picture (using OpenFileDialog) and its shown in a fixed size picturebox. I want this picture to fit in the picturebox even if the resolution is high.
What property do I need to set inorder to let my image AutoScaleToFitIn the PicutreBox?
You could set the PictureBox.SizeMode property to StretchImage.
Look at the SizeMode property

I am new to C# and I'm making a C# .NET Framework Windows App Project.
I wanna make an add button but, when I change it's size the icon wont do the same!
First it is like this
Than it would become like this
I'm sorry if my grammar isn't so great!🙏
I have tried to change the buttons size and I thought that the icon would change size but It didn't and now I have only a part of the icon
I assume that you have a Windows Forms App (WinForms). Buttons have a BackgroundImageLayout property you can set to Zoom; however, you will have to assign the image to the BackgroundImage property instead of the Image property for this to work.
You can also set BackgroundImageLayout to Stretch if you want to fill the button with the image and you don't mind a possible distortion of the image this involves.
If you have a PictureBox, you can assign the image to the Image property and set the SizeMode property instead. It has similar settings.
In the button properties change BackgroundImageLayout to Stretch
I would like to know how to create an effect of a magnifying glass for a picturebox.
Not zooming the picturebox but magnifying a part of the the image in the PictureBox control (circle or rectangle) and setting the size of the glass and the magnification factor.
It may only work within the picturebox control.
Language: C#
Thanks in advance !
Basically, you'd need two pictureboxes. One for the whole image and another for the magnified section. Also, you have to place the magnified picturebox according to user's mouse position.
You'll find a good article about it at http://www.codeproject.com/Articles/21097/PictureBox-Zoom. Just change the source to show the second picturebox in appropriate place (under user's cursor position).
You need 2 picturebox objects, one for picture itself and second for magnified area.
Next load picture into memory, you haven't specified source of the picture but in any case I recommend using streams.
Then create bitmap image in memory.
Using Image method set property of a picturebox.
To create source image for magnifying picturebox you need to clone selected part (calculating dimensions of a new picture area). Whole thing is not as trivial as you may expect as clone method accepts Rectangle objects as an area selector and generally works on rectangles rather than circles to copy selection. I also recommend to Dispose() unused bitmap objects as soon as possible.
Hope this helps.
I have a PictureBox with it's Dock set to Fill. I want to load pictures that are smaller than the PictureBox size. I don't want them to get stretched, is there a way to achive this? I have the SizeMode set to None but this doesnt help.
Any ideas?
The PictureBox.SizeMode does not have the property None. When you set it to Normal or CenterImage your image shouldn't be altered within its size.
Did you try to set SizeMode to CenterImage? I think that would solve it.
Use PictureBoxSizeMode.AutoSize which makes PictureBox sized equal to the size of the image that it contains.
To get more information about PictureBoxSizeMode , you can have good tutorial over here.
I've set the backgroundImage property, and still the image covers all the UI, what am I doing wrong?
Thank you.
You're not providing enough information, but possible scenarios are:
The PictureBox is set to cover the entire form
You've not set the PictureBox's BackgroundImage property but the one of the form itself
You have set the PictureBox to stretch the image (goes together with 1.)
Why are you setting BackgroundImage at all? Usually you put a PictureBox on the form, assign the image and make sure that it has the appropriate size (or stretches, which I assume your's is doing). Usually you don't need the BackgroundImage property to display an image in the PictureBox.
Yes, Image and BackgroundImage, both of them
I assume you've set the BackgroundImage for the form and are now trying to clear the BackgroundImage of the PictureBox, that's why the "Clear" button is grayed out and that's why you see both of them.
Go ahead and select the form first by clicking somewhere on it where there is no other control, and then go to the BackgroundImage property and clear it.
how to Resizing the Windows form elements on resizing the form? is there any way to set the width of picturebox, panel, etc 100% like CSS? suggest me some help for best practices of layout? When i resize the Windows form, I want that Image size also change when i resize the image. like Windows Picture Viewer
You would probably be okay with the Anchor property of the controls.

You should look into Control Docking, it'll probably suit your needs.
What you may want is to set the properties of the image control to fill the image inside.
Steps:
I created a new windows form
I added a picture box to the form
I set the picture box "Dock" property to "Fill"
I added an image to the picture box
I set the SizeMode property to "StretchImage" ("Zoom" might better fit your needs")
