trapping the 'Filter' command button

[Brad Pears]

Is there a way that I can check to see if the user has clicked or unclicked
the filter button that appears as part of the tool bar?

I have a situation where through code, I set a filter - which activates the
filter button. Then when the user wants to clear the filter, they simply
check this button.

However, when they uncheck this button, I want to run some code and reset
the filter to something different based on their user rights etc...

Can someone help me?

Thanks,

Brad
