scope: this,
keydown: this.onGridKey,
columnresize: this.verifyLayout,
columnmove: this.refreshFields,
reconfigure: this.refreshFields,
beforedestroy : this.beforedestroy,
destroy : this.destroy,
bodyscroll: {

fn: this.positionButtons
}

var scope = this;

columnresize: this.verifyLayout,
columnmove: this.refreshFields,
reconfigure: this.refreshFields,
destroy : function () { scope.removeAll(false); scope.destroy(); },
