Adding placeholder text to textbox

by

Wouldn’t that just be something like this:

Textbox myTxtbx = new Textbox();
myTxtbx.Text = "Enter text here...";

myTxtbx.GotFocus += GotFocus.EventHandle(RemoveText);
myTxtbx.LostFocus += LostFocus.EventHandle(AddText);

public void RemoveText(object sender, EventArgs e)
{
    if (myTxtbx.Text == "Enter text here...") 
    {
     myTxtbx.Text = "";
    }
}

public void AddText(object sender, EventArgs e)
{
    if (string.IsNullOrWhiteSpace(myTxtbx.Text))
        myTxtbx.Text = "Enter text here...";
}

Thats just pseudocode but the concept is there.
