datagrid problem

Question

I have a datagrid in my application and it gives me an error if i try to delete everything in the table(only if there is a null value on the very bottom row of the table. I get a nullreferenceexception and I dont know where it occurs. It seems to happen within the function of the datagrid itself(possible bug). Any help is appreciated. Thanks
