Click is an event that fires immediately after you release the mouse button  So if you want to check in the handler for button2 Click if button1 was clicked before  all you could do is have a handler for button1 Click which sets a bool flag of your own making to true   private bool button1WasClicked   false   private void button1 Click object sender  EventArgs e        button1WasClicked   true     private void button2 Click object sender  EventArgs e        if  textBox2 Text    textBox3 Text  amp  amp  button1WasClicked                 StreamWriter myWriter   File CreateText   c  Program Files text txt            myWriter WriteLine textBox1 Text           myWriter WriteLine textBox2 Text           button1WasClicked   false
