Accepted answer
If I am seeing it correctly, all you need just 3 (or 4) lines.
Label1.Visible = TextBox1.Text == String.Empty;
Label2.Visible = TextBox2.Text == String.Empty;
Label3.Visible = TextBox3.Text == String.Empty;

Boolean result = TextBox1.Text == String.Empty || TextBox2.Text == String.Empty || TextBox3.Text == String.Empty;

if(result)
  MessageBox.Show(""); // show appropriate message here
else
  MessageBox.Show(""); // show appropriate message here

Here you go.
Change it as needed.
private bool IsFilled()
{
    // default always returns false
    bool result = false;

    // conditions for true
    // TextBox1, TextBox2 or TextBox3 may have an empty string
    bool result = (TextBox1.Text.Trim().Length==0) ||
                  (TextBox2.Text.Trim().Length==0) ||
                  (TextBox3.Text.Trim().Length==0);

    return result;
}

protected void Button1_Click(object sender, EventArgs e)
{
    // check state
    Label1.Visible = IsFilled();
    Label2.Visible = IsFilled();
    Label3.Visible = IsFilled();

}
Have a great day.
