Is it possible to get rid of the checkerboard pattern?

Is it possible to get rid of the checkerboard pattern and replace it with pure white background, when moving sections or using delete button?

Welcome @Wolobofe.

There are a few concepts that you need to understand to properly answer your question.

The checkerboard pattern is just an indicator that shows where pixels are transparent.

When you press Delete, you are erasing pixels (leaving a transparent region).

Similarly, when you move selected pixels, you leaving a transparent region in their original place (you moved them, right!)

To add colour to the transparent region, you need to Fill it.

 

You would do well to read the paint.net Documentation.

Click the Help icon or go here https://www.getpaint.net/doc/latest/index.html

 

Look at the 'Edit menu' page  https://www.getpaint.net/doc/latest/EditMenu.html 

Note that the Delete key is the shortcut for Erase Selection (leaving transparent pixels).

Note that the Backspace key is the shortcut for Fill Selection (leaving filled pixels).

 

Now have a look at the 'Keyboard and Mouse Commands' page https://www.getpaint.net/doc/latest/KeyboardMouseCommands.html

In the Tools column on that page, click on Paint Bucket.

Note that Backspace fills the selected area with the Primary colour and Shift+Backspace fills it with the Secondary colour.

See the 'Color'' page to understand about Primary and Secondary colours.

 

Now you should explore the 'Tools | Fill Tools | Paint Bucket Tool' page and have a go at filling transparent regions (you may need to adjust the Tolerance slider when doing this).

Finally, I'd recommend that you get to grips with layers.

See the 'Layers | Layers Window' and the 'Working with Layers' pages.

Depending on what you are trying to achieve, it is often sensible to copy a selected region and paste it to a new layer before moving it, rather than just moving it in the original layer.


The above may seem a lot to take in. But if you work your way through the Documentation and experiment as you go, you will gain a lot better understanding of what you can do in paint.net and why the tools work the way they do.
 

Come back and ask any further questions if you need help.

The checkerboard pattern doesn't actually exist. If you want a white background, then create a new layer, move it to the bottom, and fill it with white.
