Please look at our ASP.NET example application HnD, http://www.llblgen.com/HnD
Databinding in one-way scenario's: simply bind the object (collection, typedlist etc.) to the grid/control
Databinding in two-way scenario's: use the LLBLGenProDataSource(2) controls (the '2' version for adapter).
See for example in the HnD application (which is this forum
) the page GUI\Admin\ManageSupportQueues.aspx. This page uses a datasourcecontrol for 2-way databinding.
Also see the documentation: USing the generated code -> Adapter/selfservicing -> Databinding at design time and runtime -> Databinding with ASP.NET 2.0
