It can display horizontal and vertical scrollbars for scrolling through the text and supports vertical scrolling with the mouse wheel. This sample also shows
how you can restrict character input on the text area. The default when this is run will not allow the number 0 or caps based on the restrict range shown. The
sample also shows how you can specify a direction on the text."/>
