Problem while navigating the records..

Question

Hariom ( A word to wish)... I used commandobject, data adapter, dataset etc. for connection and an object of BindingManagerBase class in my project. While I click on any of the navigation button i.e MoveNext, it shows an NullPointer.. type of exception and any object is not set type of description shows. I m surprised why it is happening while i used the same type of code in other programs to. I took all namespaces and common objects to connect the database in Module which is very separate then the Form where BindingManagerBase class' object is created. Could it be the reason to raise the exception. Thanx in advance.
