Question

I have to copy rows from one table to another. In the source table I can have RowError set on rows.
When I do this:

targetTable.BeginLoadData();
targetTable.Load( new DataTableReader( sourceTable ) )
targetTable.EndLoadData();

The target table does not get row errors copied on its rows from source table.
Can anyone tell what am I supposed to do to make it work?
Thanks.

EDIT: I do not want to lose the data already present in the target table. Nor do I want to change the reference.

Try this:

targetTable = sourceTable.Copy();

Creating a reader won’t give you the expected result in this case, because its (reader) goal will be extracting the value of each row, not the appendant properties.

Update:

In this case, you should:

foreach (DataRow drImport in sourceTable.Rows) {
    targetTable.ImportRow(drImport);
}

Sorry, just before posting I’ve seen your other observation about the reference. I’m afraid you can’t have the same row (same reference) assigned to two ore more tables. See this.
