Tic Tac Toe game

Hello,

I'm gonna make a Tic Tac Toe game in C#(Windows Forms) and have made the menu. Then I made 9 PictureBoxes, 3 in each row where you will be able to press on and then it shows X or O. But I have problems with this part, I don't know how I should build it up. How do I get started with making the click functionality? What is the best to start with?

I'm thankful for all help!

In the form editor, add a click handler for each picturebox. To do this, just doubleclick on each of the pictureboxes. Then open the xxx.Resource.cs file to make sure the handlers were added.
