Changing default value of Boolean filter of the grid?
I am using GXT's filter grid(http://www.sencha.com/examples-2/#filtergrid). i have set boolean filter for one of the column. but boolean filter by deafult "No" will be in selected mode. but i dont want to set anything default. both Yes and No should not be checked initially. if user applies filter then only either Yes or No should be in selected mode.
