Trick: Clearing data from all TextBox Fast

If there have lots of textboxes in the form And wants to clear the content fast, then use the following code. I assumed that all the textboxes inside a groupbox control[i.e., groupBox1].

        foreach(Control ctrl in groupBox1.Controls)
        {
           if(ctrl is TextBox)
           {
              TextBox t = (TextBox)ctrl;
              t.Text = String.Empty;
           }
        }

Note: If the textboxes are on the form directly then replace the "groupBox1.Controls" to "this.Controls".
