How to make textbox text disappear when I click on it

Question

I managed to create textboxes dynamically in C#. When a textbox has text, can I make it disappear when I click on it?

I need to put a word inside textboxes that is the result of a select in Oracle.

Assign a value to the Text property of the TextBox. You could subscribe then to the GotFocus event, and set the text value to an empty string.

// Holds a value determining if this is the first time the box has been clicked
// So that the text value is not always wiped out.
bool hasBeenClicked = false;

private void TextBox_Focus(object sender, RoutedEventArgs e)
{
    if (!hasBeenClicked)
    {
        TextBox box = sender as TextBox;
        box.Text = String.Empty;
        hasBeenClicked = true;
    }
}
