I have two queries
1. Binding of model property to xtype properties : I want to bind the properties of xtype to my model fields so that instead of accessing the UI element to change the properties lik visibility,enable etc i can do the changes on model fields and that will change the UI element properties directly.
2.I am using action column in which i have one item (for shared/private icon) and i assigned handler also so that when i click on icon i change the private to shared and shared to private.In hanlder i m changing the icon source but that is not reflecting on ui.I tried with grid.refresh(); and icon is started reflecting.
But the thing is if i am changing the icon in one column ,why do i need to refresh the whole grid because in future this may affect the performance.Kindly suggest.
