I am using a Typed dataset and write changes to my data through my business logic.

I pass data via parameters into my update routines and write to the rows like this:

MyDataTable o1 = new MyDataTable();
MyRow o2 = o1.NewMyRow();
o2.firstname = x
o2.lastname = y

This works great, but if the contents of X or Y are greater in length than the fields o2.firstname or o2.lastname, I will get an error. What is the best way of trapping or preventing this type of error?

Thanks,

Jerry
