Question

How can I have the same text being entered in a text box to some other textboxes? I mean when I am typing in a textbox, the same string should go inside other textboxes on the fly!

Which event should be used in this case?

Answer 1

TextChanged event.

private void currencyTextBox_TextChanged(object sender, EventArgs e)
{
  textbox1.Text = currencyTextBox.Text;
  textbox2.Text = currencyTextBox.Text;
  textbox3.Text = currencyTextBox.Text;
}
