Mimicking ADO Control Refresh

I am using a data provider class as the DataSource for a DataRepeater Control. This works for my original Recordset. However, I would like to update the recordset provided by the class, and hence, the data displayed by the Data Repeater, based on user selection.

With an ADO Control, I can make this work by assigning the ADO Control recordset statement to the new query, and then refreshing the control.

So far, I have not been able to mimic this behavior in the data provider class.

Any suggestions?

Thank you.
