Do total of text boxes in grid


Hi,
I have grid (ASP:ListView) control in my .net appliction where i have
hours information along with other fields in each record as follows:
textDay1Hours
textDay2Hours
textDay3Hours
textDay4Hours
textDay5Hours
textDay6Hours
textDay7Hours
textTotalHours
User can enter value for hours in a day. On change of day hours i need
to show total in textTotalHours. Can someone give some guidence on how
to do that.
Thanks
