Bobby,

>i've made a windows application creating business objects using Mere Mortals. i initially used the mmDataGrid using the BindingSource property to bind to my data source. next i tried using Ultragrid of Infragistics but the DataSource property could not bind to my data source.

You've got a few options. If you simply want to use Infragistic's regular data binding as specified in their documentation, you can do that and the control can co-exist peacefully with other MM .NET controls. This isn't a bad option since it normally takes just a few lines of code to bind a data grid.

If you want to use MM .NET data binding, you need to subclass the Infragistics data grid and implement the ImmBindingDataGrid interface. For an example of how to do this, check out the source code for the mmDataGrid class.

Regards,
