Programmatically accessing data from DataSource controls

16 May 2007 10:06

C# ASP.NET 2.0 ADO.NET

For the main part, the DataSource controls are incredibly easy to work with. You just drag them onto your page in Design View, wire them up to a connection and provide some kind of command (ad hoc sql query or the name of a stored procedure - saved query in Access), then link them to a databound control on the page using its DataSource property. Then you run the page and all your data appears. But what if you want to get at one or more values from the returned data to do something else with it, like display it in a control that doesn't expose a DataSource property?
