Paul,

Have you tried using DataSet or DataTable .Merge()? Check out the second Tip from my Tips column in the current .NET Magazine here:

http://www.levelextreme.net/ViewPageArticle.aspx?Session=6F45495A76536D74527A303D203255557039742B6A2B746955644A3873484A793370773D3D

Well, actually, let me just copy it here (it's funny because this tip was originally inspired by a post from Mike Cole ... I guess he doesn't remember his own posts <g> ... I elaborated on it a bit for my tip column though):

If you want to create a new DataTable with data from an existing DataTable, you can always use the DataTable.Copy() method. But, what if you want to copy that data (or even a subset of that data) to another existing DataTable? Here's an easy trick:

DataRow[] rows;

// To copy all the rows
rows = MyOldTable.Select();
MyDataSet.Merge(rows);

// To copy a subset
string FilterSubset = "code = '4'";
rows = MyOldTable.Select(FilterSubset);
MyDataSet.Merge(rows);

Unfortunately, there is one drawback to this approach ... this signature of the .Merge() method is only supported by DataSet (in other words, you can't use the DataTable.Merge() method).
But, if you're using Visual Studio 2005 ... then no worries mate! There's the new .ToTable() method to the rescue!

DataTable dtCopy = MyOriginalTable.DefaultView.ToTable();
MyNewTable.Merge(dtCopy);
