DataGrid Question

[Harry]

Basicly I have a dataset that contains tuples with an identifer and string.
For instance {1, "Hello"}, {2, "World"}, {3, "Foo"}. Now using the example
datatset as a data source to a datagrid I would like it combine like IDs in
a single row such that in this example I would have a datagrid with two rows
{1, "Hello, Foo"}, {2, "World"}. Is this possible by overriding the datagrid
events ItemCreated or Bound? If so could someone elaborate.

Also, would it be possible to perform this in a stored procedure? If so
could someone elaborate.
