Attach a custom method to a DataTable

I would like to override the DataTable.Rows.Contains() method to encapsulate
the DataTable's DefaultView's FindRows() method. It would be nice to be
able to test an array of alternate keys in addition to the primary key.

Questions:
* I'm assuming that I can do this in the XSD file's Designer.vb file. Is
this the best location for this?
* I've noticed that changes to the DataTable's Select commandText seems to
re-created the Designer file. Am I correct in this? Is there a way to
perserve my custom code in these situations?
* Is there a better way to approach this?

Thanks,

Craig Buchanan
