Dear Jason

When binding the ObjectDataSource to the GridView with the
DataSourceID property you have no control over when the binding
occurs.

If there are problems because of (intially) null parameter values then
set the "DefaultValue" property of each parameter to something
meaningful (DefaultValue is used when the actual parameter source - in
this case a web server control - has null content).
