title: GXT Grid filtering a store
body: <p>I understand that in GXT 3.0 grids are pulling their data from a store (in my case a list store). I am trying to implement a search function to help filter through some of the results in the grid dynamically. However, I am having trouble determining the best method to do this. I have considered doing this server side by modifying the source file..but ultimately I just want to toggle the displaying of a row if it doesn't contain a desired string. Any suggestions for how to best approach this?</p>
