NumericalUpDown in Asp.net....??

Question

I am developing a web application where in,  i am showing the calender for date and start and end time. For the display of time there is no such control as in windows.form like numericupdown in asp.net.
so i used 3 textboxes and 2 buttons which resembles the control for windows timer setting
iam not able to handle the event for mouse click event on the textbox, so that i can get a spinner look for the text box....and can also increment the values on the button click event .
is there any other way to do this.....?
Please help....
