Hi

I have a Master Detail Table in DataSet.
And I define the expression of one columns in detail by referring parent columns.

When I insert parent table, I saw the following exception

System.Data.VersionNotFoundException
Additional information: There is no Original data to access.

A parent table may be referenced in an expression by prepending the column name with Parent

You can find the sample program in the attachmens.
I should mention that I use c# .net2003 and sqlserver 2000
