I have 2 unbound columns being calculated
I want that the sum of the 2 unbound columsn should not exceed 100
How can I validate that
Hi,
You could implement IDataErrorInfo (http://msdn.microsoft.com/en-us/library/system.componentmodel.idataerrorinfo(v=VS.95).aspx) or INotifyDataErrorInfo (http://msdn.microsoft.com/en-us/library/ee652637(v=VS.95).aspx) on your data type and validate that when one of the bound columns that participate in the calculations is changed the sum does not exceed the boundary.

How can it be done when 2 unbound columns are involved
