As you can see, calling this method removes the need for a switch altogether.

your code is a WTF! All you're doing is lower-casing the header.

if (textbox1.TextLength < 1)

          textbox2.Location.Y -= [int HeightOfTextbox];
      }

if(String.IsNullOrEmpty(textbox1.Text))

String[] myLines = {"line 1", "line 2", "", "line4"};
int lineheight = 23;//pixels between the labels

Error	646	'System.Web.UI.WebControls.Label' does not contain a definition for 'Location' and no extension method 'Location' accepting a first argument of type 'System.Web.UI.WebControls.Label' could be found (are you missing a using directive or an assembly reference?)

if (String.IsNullOrEmpty(textbox.Text))

label.Location = new Point(textbox.Location.X, (textbox.Location.Y - textbox.Height));
