Connecting 2 Textboxes values temporarily

I want to create 2 Textboxes (txt1, txt2) and when I write in txt1 then txt2 should reflect the same text what i typed in txt1. For ex. When we create a new Solution in Visu开发者_如何学Goal Studio Professional, what name we give to Project, same name appears for Solution. But if we edit solution name, link between the 2 textboxes breaks. I do have some idea about it, to do it with textChange event or in fact many similar events, but not sure that they are the best methods. I am using Winforms, C# 4.0, Visual Studio 2010 (if this info matters) If my question is not clear, just make a comment I will try to elaborate. Thanks.

With the given definition of the requirement, adding TextChanged EventHandlers is the way to go.

private void txt1_TextChanged(object sender, EventArgs e)
{
    txt2.Text = txt1.Text;
}

private void txt2_TextChanged(object sender, EventArgs e)
{
    txt1.Text = txt2.Text;
}

Consider adding an event handler for txt1_TextChanged and txt2_KeyPress.

txt1_TextChanged would assign txt2.Text: txt2.Text = "c:\" + txt1.Text;

txt2_KeyPress would unsubscribe txt1_TextChanged: txt1.TextChanged -= txt1_TextChanged;.

I solved it, so thought to post it here

txt1_TextChanged(obje....)
{
   txt2.Text = txt1.Text;
}

txt2_TextChanged(objec...)
{
   if(txt2.Focused)
   {
      txt1.TextChanged -= new EventHandler(txt1_TextChanged);
   }
}

Hope it helps.
