textbox event handler?

textbox event handler?

• stack

  You can use Click event for your textbox3. Code inside the click event would look something like:

  double value1, value2;

  if (!double.TryParse(textBox1.Text, out value1))

  {

  MessageBox.Show("Please enter numeric value in textBox1");

  return;

  }

  if (!double.TryParse(textBox2.Text, out value2))

  {

  MessageBox.Show("Please enter numeric value in textBox2");

  return;

  }

  double result = value1 + value2;

  textBox3.Text = result.ToString();

  i only find this...

  There's a MouseClicked event handler, but, this one is only raised when you really click it using the mouse.
  
  Have a look at the 'Enter' event of the textbox. This one is raised when the Textbox receives focus.

  Enter is indeed the preferred way, since it is raisend whenever the control receives focus, no matter how ... (by mouse, by keyboard; ... )
