Let me add, the ds I declared exixts in the project, so I declared it of a known type. Code looks like this:

Protected WithEvents ds as ClosingAgents.ds

In the Sub InitializeComponemts:

Me.ds = New ClosingAgents.ds()
CType(Me.DS,System.ComponentModel.ISupportInitialize).BeginInit()

I think that is all the code.

good luck,

>>Michael, I'm not certain of this, but I think it has to do with the InitializeComponent Sub in the codbehind page. Notice when you drop a dataset on a page the ds is declared at the top of the class WithEvents and instaniated in the InitializeComponent Sub. I haven't tried adding a control like this programmatically, so don't know how that would work. Seems it should. I normally add the dataset to the designer, let it generate its code, then modify it in the codebehind.
