title: Make the Enter key act like the submit button
body: <p>How can I make it where some one presses the enter key on my form it will submit this code ?</p>
  
  <p>Ive tried the KeyPress events etc... but I can't seem to figure it out.</p>
  
  <pre><code> private void
   xTripSubmitButton_Click(object sender, EventArgs e) { 
      //  Calculates the numbers from the input and output boxes/labels
      Miles = double.Parse(this.xTripDestinationTextBox.Text);
      Mpg = double.Parse(this.xTripMpgTextBox.Text);
      Price = double.Parse(this.xTripPricepgTextBox.Text);
      Output = Miles / Mpg;
      Coutput = Output * Price;
  
      //displays a message and the result for the numbers the user inputs
      this.xTripOutputLabel.Text = "Total gallons you would use: " +
          Output.ToString("0") +
          Environment.NewLine + "Total amount it will cost you: " +
           Coutput.ToString("C"); 
  
      }
  </code></pre>
