Actually The values from txtunit is user input n the value of txttotalamt is constant. if the user enters the 10 in txtunit, the amount shld get caculated and displayed on txttotalamt after multiplying. the link u shared has 3 textbox. i m working with 2. if the entered units on txtunits is 10 n the constant amt is 100 the multiplication should get displayed on txttotalamt i was trying int i=100; txttotalamt.text=txtunits.text* convert.tosrting(i); but it is displaying an error that * cannot b used
