I have a button at top that I wire up to do a filter reset. I show that button whenever a filter is applied. However in the columnMenu filter clear, it does clear the filtering of the data, but I need it to hide that button IF there are no more filters. I am overriding the filter function with a custom filter
Questions:
1) Is there a way to tie into the clear event that is fired from filterMenu to update certain UI elements?
2) Is there a way to identify if ANY filter is on a grid since the filter function loops through column by column and I want to know if ANY filter is applied?
Thanks.

Hello John,
You could get the current filter information for the Grid via the filter method of the dataSource. When the Grid is initially loaded with no filters applied, it returns undefined. When a filter is applied at some point and then cleared it returns null. Both of the current issues could be handled if you bind to the dataBound event of the Grid and check the dataSource filter data.
