Add a variable to a command

Thank you! That did it for me.

That made my code way smaller, reducing these behemoth switches with 42 cases ;-)

If you're using .NET 2.0 or later, try this:

        private void MakeNormal(int buttonNR)
        {
            Button b = (Button)(this.Controls["button" + String.Format("{0:D2}",buttonNR)]);          
            b.Text = "l";
        }

If the buttons are inside a panel or groupbox, rather than directly on the form, then change 'this' to 'panel1' etc.

Thank you for your help!

However, I have a problem with implementing it. Your code

((Button)(sender)).BackColor = Color.SteelBlue;

relies, as far as i understand it, on the button itself calling this event. (so the button is the "sender" )

Since I'm going to call such a method myself, the sender won't be the button.

Somehow I wonder why there isn't an option to evaluate variables first, and afterwards embedding them in a command, so that in

Button[NR].Text = "abc"

the contents of the variable [NR] gets put into the command itself, then forming

Button123.Text = "abc";

But the again, maybe I'm assuming that languages are more powerful than they are =P

If I understand the question correctly you are looking for something like this; in this example I have three buttons on a form (buttons 1, 2, and 3) and I have handling them all within a single method; that method uses the sender argument to determine which button was clicked and once I know which button was clicked, I set the fore and background color properties on the button to show that it was clicked.  You could just as easily change the text property or do some other action.
