I have used data combo for students and data grid for fee.cause one student
have many fee entries. I have coded in the click event that when student
change thier respective entries of fees are shown in the data grid . its
working fine but the problem is that when there is a new student i.e not
having entry in fee table vb return erro.
pls help me how can i solve that problem , is there any other better way
to do that or what ever so
thanks in advance for help
