Ian,

>Here is basically where I am at with this issue. At this point I have no rows in either the grid or the dataset of the business object and the screen displays "No Data Found" from the emptydatatext property. (oMachCat is the registered business object)

> this.oMachCat.Entity.fkcompid = int.Parse(Session["CompPK"].ToString());

> this.oMachCat.Entity.machcnt = int.Parse(txtMachCnt.Text);

> this.oMachCat.SaveRow();

> this.grdMachCat.EditIndex = -1;
> this.BindControl(this.grdMachCat);
>At this point the grid still has no rows and the screen displays "No Data Found". If I continue to add records the dataset gets more and more rows, but the grid never displays and always has a row count of 0. Also of note is that when I start the business object with a row already in it then the grid displays and shows the row, but still will not show any of the rows I add after that point. Any ideas?

The call to BindControl() should do it for you. I recommend rechecking your grid's binding settings, and if all is good, set a breakpoint in mmBusinessForm.BindControl() and trace through to see what's happening. If you're unable to figure this out by tracing through we may need to set up a GoToMeeting session so I can look at your development machine to see what's going on.

Best Regards,
