How Can I Use SqlDataSource To Read A Row?

The new databound controls are great, but somehow doing the simpler things has gotten harder.The code is in a function that is passed pollid.  I want to use SqlDataSource to get the smallest value of answerid where pollid = the value passed for pollid.  For example:
"Select top from PollAsnwers where pollid=" & PollId & " order by AnswerId"
 I can set up the SqlDataSource for a data reader to fill a GridView control, but that isn't what I want to do.  In fact, I can't find anything on SqlDataSource that doesn't also involve the GridView control.
I have so far:
Dim myConnection As SqlConnection
Dim myCommand As SqlCommand
Dim myReader As SqlDataReader

myConnection = New SqlConnection()
myConnection.ConnectionString = ConfigurationManager.ConnectionStrings("UserPolls").ConnectionString

myCommand = New SqlCommand()
myCommand.CommandText = "Select top from PollAsnwers where pollid=" & PollId & " order by AnswerId"
myCommand.CommandType = CommandType.Text
myCommand.Connection = myConnection
myCommand.Connection.Open()
Now assuming I have a single row of data, how do I read the value of Answerid?   If I have this wrong, what should I have?
