Jim Booth had a great reply on this topic in the last few days. His
response went into more details as to why it is happening. There are
two solutions to this issues beyond what has been stated:

1.) Use a paramterized view instead of a cursor.

2.) Set all the properties of the grid by calling a method to reset
everything.

Hope this helps...
