Try this which should clear the textbox when you press any key after clicking the '=' button though it could easily be altered to only clear it if a number key dot or backspace key (say) were pressed: // add this private field private bool equalsPressed = false; private void button1_Click(object sender EventArgs e) { // existing code to calulate and display result equalsPressed = true; } private void textBox1_KeyDown(object sender KeyEventArgs e) { if (equalsPressed) { equalsPressed = false; textBox1.Clear(); } // any other code already in this eventhandler }
