Dataset: expression columns recalculation

TheMSsForum.com: The Microsoft Software Forum

Hi there

I'm having a typed dataset, where a datatable has some columns which are
expressions.

After doing a Merge, i was expected that my expression columns were
calculated, but they were not.

Although, if i do this
foreach(System.Data.DataColumn column in dataset.myDataTable.Columns)

{

if (column.Expression!=null && column.Expression.Length>0)

column.Expression =column.Expression;

}



they are calculated...

is this by design ?

thanks!

Hi Hugo,

No, it is not By Design. Which version of framework you are using?
