    solve this case use persist object

     

        public syncSelection(ids: ISelectionId[], row: number, col: number, selector: Selector) {
        if (row == null) return;

        
        let enumerationObject: powerbi.VisualObjectInstanceEnumerationObject = {
            containers: [],
            instances: [],
        };
        let persistProperties : VisualObjectInstancesToPersist;

        if(row == -1){ // remove from format panel
            this.settingDataPoint(enumerationObject, "dataPoint");
            persistProperties = {
                remove: enumerationObject.instances
            }
        }
        
        this.selected.row = row;
        this.selected.col = col;
        this.selected.selected = ids[0];
        this.selected.selectionId = ids;
        this.selected.selector = selector;

        if(row != -1) {
            this.settingDataPoint(enumerationObject, "dataPoint");
            persistProperties = {
                replace : enumerationObject.instances
            }
        }
        // console.log('ini coba persist', persistProperties);
        this.host.persistProperties(persistProperties);
    }

    but I still don't understand remove and removeObject how to use it, to confused

    it is imposible to update format panel when user click some row in our view?

     

    I try using this.host.refreshHostData(); this solve my problem when developing,

    but this not working when we use pbiviz package because enumerateObjectInstances never called
