Hi.
I use a typed dataset with one calculated column with a simple expression (like "colA*colB"
. When I call the GetChanges() method, something happens in the dataset, which in the end causes an error.
Here is output from the immediate window:
[tt]
?dsDataset1.GetChanges()
{"Cannot remove this column, because it is part of an expression: calculatedCol = (colA*colB)." }
System.SystemException: {"Cannot remove this column, because it is part of an expression: calculatedCol = (colA*colB)."}
m_paramName: null
Message: "Cannot remove this column, because it is part of an expression: calculatedCol = (colA*colB)."
ParamName: ""
[/tt]
Some ideas what is going on and what to do with it?
Thanks.
