Mark DataTable dirty

Hi;

How can I mark a DataTable as dirty (has changes)? I need to do this
because when I add a DataColumn to a DataTable, it does not set
HasChanges() to true.

thanks - dave

Dave,

First of all, a datatable will be marked as dirty if its rows are dirty,
so you need to change the rows. As soon as you change/set a value on a
row, it becomes dirty. You may simply loop the table and do something
like that:

for each row as datarow in table
row(0) = row(0)
next

As dumb as it seems, the row will be marked "dirty" even if there's no
change. But you probably want to insert data in your new column?
