    Why you don't use javscript for that calculation?

      If you have no idea what the answer is, it's best to stay silent. Your code is not functionally different from his, and both suffer from the same basic problem.

              hi you know , i think you`d better not do that like this !!! :-D because ontextchanged , sends the information to the server andyour page relodes and takes so much time ! it`s better to do this on client side with java script something like this :

              var quantity = document.getElementById('txtqty').value;
              var price = document.getElementById('txtproductprice').value;
              document.getElementById('txttotalprice').value = quantity*price;

              :cool:

                        Dear Guys, You People have left one thing,onblur event(given by padmanabhan) should be written to Two text boxes(txtqty and txtproductprice).In Function we have to Check whether these two TextBoxes are not null and if it is not so , Then multiply and display data in third textbox. Writing an event for third textbox is of no use here. Sundeep Ganiga
