I wrote a small program working with Timer from component tab. my program object was to display the text  in textbox server control if the textbox server control is empty and if textbox server control is not empty then clear the content of textbox server control. I wrote the statement in timer elapse event but it is not working properly. Please tell me how to do it and also I can I do animation like job working with timer control which is most often done by javascript. Please tell me about timer control in detail with sample code.
