DataGrid control contains GetChanges() method to get a DataSet of rows that
have changed.

I would like to write a method GetSelectedRows() that returns a DataSet of
selected rows (may be multiple rows).  I tried to do this by extending the
DataGrid control and writing the following method:

public DataSet GetSelectedRows()
{
  ...
  CurrencyManager cm = (CurrencyManager)BindingContext[myGrid1.DataSource,
myGrid1.DataMember];

  DataRow dR = ((DataView)myGrid1.DataSource).Table.Rows[cm.Position];

 ...
}

I have two issues with this code:
1) Even when multiple rows are selected, only one row is returned.  How can
I get a collection of selected rows?
2) This works only if the data in the DataGrid is not sorted.  If I first
sort the table by any column and then select a row, say second one, DataRow
returned corresponds to the row that was in second position before sorting,
and not after sorting.  Thus a row that is not selected is returned.

Thanks for help in advance.
