Is it possible to show/hide the scroll bar in a text box only when the line count in the text box is more than the number of lines displayed?

Use overflow: auto . Scrollbars will only appear when needed. (Sidenote, you can also specify for only the x, or y scrollbar: overflow-x: auto and overflow-y: auto ).
For vertical scrollable bar use the x and y axis. Set the overflow-x:hidden; and overflow-y:auto; that will automatically hide the horizontal scroll bar and present only vertical scrollbar. Here the scroll div will be vertically scrollable.
Definition and Usage. The overflow-x property specifies whether to clip the content, add a scroll bar, or display overflow content of a block-level element, when it overflows at the left and right edges.
Consider using the RichTextBox -- it has that behavior built in.
