I want to move an object on WinForms (with WASD) and it goes pretty well,but when I add a button at the Form, the object doesn't move anymore.
Controls like Button take focus and "eat" the keypress events. A form will always set focus to one of its child controls if there is one that allows getting focus.
Set KeyPreview = true on your form to receive these events regardless.

Default behaviour for an html button in an html form is to submit.
To prevent this add type=button to your button.

Oddly, my text boxes gets blurred after i did some changes in the form properties. I think that i changed opacity of form due to which this is happening but changed it back, nothing happened. Still stuck in this problem. Tried adding new text boxes. Same problem :(
Screenshot
You seem to have set the form's TransparencyKey property to Black. This makes everything in your form that is drawn in black color transparent.
Simply change the property to something else, or just set it to Transparent to make it only apply to completely transparent colors.
EDIT: You can also right-click the TransparencyKey property and press Reset.

When I resize my window, the StatusStrip I have located at the bottom of the form sits on top of the ListView.
How I can set the StatusStrip to be behind the list view?
I figured it out! You just have to right click on the StatusStrip and click "Send To Back"
Set Anchor property of StatusStrip to Bottom, or you can add the code on maximize - statusStrip.SendToBack()

I have a windows forms program which saves properties like its size, location, splitter bar locations &c in a properties file in hte usual way. I've noticed that whenever I close the application by right clicking on its taskbar icon and choosing 'close window', these properties don't save correctly and my application then either won't start or starts with size 0 or something.
Of course I can catch these problems and hack around them, but I would like to know what is different between closing via the form and via the taskbar, so I can handle the appropiate events.
As the first commenter to recommend the use of Form.Closed, I'm demanding my ransom money! :-)

I want to build the Pentomino game in C#/XAML for Windows 8(8.1). I need field and draggable figures.
How I can do it? For draggable I'm using ManipulationDelta property, but how do I know that the figure is in the field and how do I attach it (figure in field)?
As your question stands, it's too broad.
For future reference, you should try splitting your problem into smaller problems, and asking seprate questions for each of them after doing some home research first.
Also, sharing some code about what you've tried can get more people to help you.
Having said that, I've never worked with XAML, though I've worked with C# for some time now.
About your problems:
For pentomino you will need a board. using Grid or DataGridView sounds like a good approch to me.
For representing your figures, your grid can be queried to find out if your figure can be droped on a certain square. Prepare for writing some for loops.
Abput drag'n drop, here are some links that you may find useful:
