Check if TextBox is empty and return MessageBox?

Question

I made this statement to check if TextBox is empty, but the MessageBox always shows up wether the TextBox is empty or not.

    private void NextButton_Click

Becasue is a TextBox already initialized would be better to control if there is something in there outside the empty string (which is no null or empty string I am afraid). What I did is just check is there is something different than "", if so do the thing:

 if (TextBox.Text != "") //Something different than ""?
        {
            //Do your stuff
        }
 else
        {
            //Do NOT do your stuff
        }
