Set their text to an empty string?

Answer 2

To "clear" the data :

Text1.Text = String.Empty;
Text2.Text = String.Empty;
Text3.Text = String.Empty;

Answer 3

You could set the text of the textbox to an empty string.

Text1.Text = "";
Text2.Text = "";
Text3.Text = "";

You could also define your own extension method.

public static class ControlExtensions
{
    public static void Clear(this TextBox text)
    {
        text.Text = "";
    }
}

Then, just include a using directive for the namespace you defined your extension class in, and you can do:

Text1.Clear();
Text2.Clear();
Text3.Clear();
