Entring same text to all textboxes while writing in one textbox

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

You can use TextChanged event. This event raises whenever there is a change in content of TextBox . You will have to handle it in all the textboxes . If there is any change in one copy this change to all but it is an ugly solution.

Also take a look at how Bindings work. It will be a much cleaner solution. Bind all the textboxes to a single variable . When the value in one textbox will change the associated variable will change and hence value in all the textboxes will change

Answer 2

TextChanged event.

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

Answer 3

使用TextChanged事件
