So as a follow up, I discovered another method to add the necessary columns directly to the Mtl EpiBinding…see code:

private void edvMtl_EpiViewNotification(EpiDataView view, EpiNotifyArgs args)
{
	// ** Argument Properties and Uses **
	// view.dataView[args.Row]["FieldName"]
	// args.Row, args.Column, args.Sender, args.NotifyType
	// NotifyType.Initialize, NotifyType.AddRow, NotifyType.DeleteRow, NotifyType.InitLastView, NotifyType.InitAndResetTreeNodes
	if ((args.NotifyType == EpiTransaction.NotifyType.Initialize))
	{
		if ((args.Row > -1))
		{
			if (!(edvMtl.dataView.Table.Columns.Contains("Width"))) 
			{
			edvMtl.dataView.Table.Columns.Add(new DataColumn("Width"));
			edvMtl.dataView.Table.Columns["Width"].ExtendedProperties["ReadOnly"] = true;
			}
			if (!(edvMtl.dataView.Table.Columns.Contains("Length"))) 
			{
			edvMtl.dataView.Table.Columns.Add(new DataColumn("Length"));
			edvMtl.dataView.Table.Columns["Length"].ExtendedProperties["ReadOnly"] = true;
			}
			if (!(edvMtl.dataView.Table.Columns.Contains("Thickness"))) 
			{
			edvMtl.dataView.Table.Columns.Add(new DataColumn("Thickness"));
			edvMtl.dataView.Table.Columns["Thickness"].ExtendedProperties["ReadOnly"] = true;
			}
			                      

		
		}
	}
}

Problem now is, how to populate the columns? There is data in the JobAsmbl table, can I link it through the Data Tools, or would it have to be coded directly also? Thanks for all your help so far!
