when I connect Visual basic.net 2010 with sql server 2008 by dataset and i drag table

[ebrahim haji]

I have a vb.net 2010 winform data app with sql server 2008 backend. The ID
field
in the tblClients table is an 'int' identity column that does not allow
nulls. The problem is that when I try to save the record using the
below
code;

Me.Validate()
Me.MMOBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.NNDatasetaS)

I get an 'Column 'ID' does not allow nulls' error on the second line
Me.MMOBindingSource.EndEdit(). What is the
problem and how can I fix it?

Thanks

Regards
