I don't understand your question.

Sorry. Improve my question.

Do you know much at all about programming? Each button will have a click event, and in that event you set the textbox value.

Where exactly are you stuck?

The thing can be, to write the Text property of the Button inside the TextBox, or append the text to it.

Take the following scenario as example,

C#

// Create button and write 2 to it; just as example
Button button = new Button();
button.Text = "2";

// To handle event, 
button.Click += Button_Click;

// Create a new instance of TextBox
TextBox textBox = new TextBox();

Now upon click, you can handle the event and write its value to the TextBox. Like this

C#

void Button_Click(object sender, EventArgs e) {
   // The object that raised this event was Button so change it 
   Button button = sender as Button;
   string value = button.Text; // would be '2'
   // assign (append; see the +=) this value to the TextBox
   textBox.Text += value;
}

This is a very basic example of this project and scenario, for a simple example of this I had a project for the Calculator application, you can view that application to understand this pattern, get the source code for that at https://code.msdn.microsoft.com/Simple-Calculator-34e18835[^]

Interesting one terzasek.

You can use Mouse_Down event of the text boxes. You can take a global variable or a label to hold the value of the mouse down on which textbox. and after button click get the value from label(ie. whcih textbox has been selected) and do your necessary work or calculations . I have done a small example to do this as you describe in the image in your question. just take a look on this. I hope your confusion will be cleared after checking the example.

On mouse_down set the id of the Text Box in a label and find it by name in button click and change it or do whatever..
