I'm selecting thousands of records using a data reader to populate a grid. How do I cache the data reader so I can just rebind after postbacks, without having to make a db call? Thanks!

      string SQL = "Select * from prospect order by prolast";
      OleDbCommand cmd = new OleDbCommand(SQL,oledbconn);
                cmd.CommandType = CommandType.Text;
      this.Grid.DataSource = cmd.ExecuteReader();


 Cache["dr"] = cmd.ExecuteReader() ????????  this will call read ! ,,,then  how do I cast it back to the grids.datasource ?

thanks again

guess you have posted this in the wrong channel.
To answer you question, you shouldn't cache a DataReader. You can create a DataSet (which is a disconnected object) instead and then cache it.

have a look at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnbda/html/CachingArchch4.asp
