I have a radnumerictextbox within a grid. When this value is changed in edit mode, i want to perform some calculations.
I keep getting object reference not set to a instance on this line as well as the one after that.
famIncome = Convert.ToDouble(((RadNumericTextBox)dataItem.FindControl("rntxtAnnualIncome")).Value );
Not sure what i am missing here.
Let me know how to get those values.
Thanks in Advance
