Next Previous button for Detail dialog

[reach2rv]

@minhhungit I am using a below code from your sliderevealdialog sample for next previous button. the only issue I am facing is while loading unsaved detail dialog with option of next and previous.. as the db entity id not available in this case loadByIdAndOpenDialog will not work.. can you please suggest possible solution to make this work for memorygrid.

Thanks

onClick: () => {
                        let grid = this.parentGrid;
                        let self = this;
                        (function next(loadedNewPage?: boolean): void {
                            let listIds = grid.view.getItems().map(x => x[(grid as any).getIdProperty()]);

                            if (grid !== null && typeof grid !== 'undefined') {
                                if (loadedNewPage) {
                                    let nextId = listIds[0];
                                    self.loadByIdAndOpenDialog(nextId);
                                }
                                else {
                                    let currentEntityId = self.entityId;
                                    if (currentEntityId !== null && typeof currentEntityId !== 'undefined') {
                                        let listIds = grid.view.getItems().map(x => x[(grid as any).getIdProperty()]);

                                        let currentIdIndex = listIds.indexOf(currentEntityId);
                                        if (currentIdIndex >= listIds.length - 1) {
                                            var btnNext = Q.first(buttons, x => x.title == "Next");
                                            btnNext.disabled = true;
                                        }
                                        else {
                                            let nextId = listIds[currentIdIndex + 1];
                                            self.loadByIdAndOpenDialog(nextId);
                                        }
                                    }
                                }
                            }
                        })();

sorry I have no idea at this time, these days are my holiday, happy Lunar new year
I also not sure which case and why you want to use the feature for memory-grid
Anyway, I will try to implement it later

Try to replace loadByIdAndOpenDialog with loadEntityAndOpenDialog

Thanks @minhhungit I was trying this since day one but was not sure how to fetch whole entity (this code is on common dialog).

Changed else block as follows and it works

   let nextId = listIds[currentIdIndex + 1];
   let nextentity = Q.tryFirst(grid.view.getItems(), x => x[(grid as any).getIdProperty()] == nextId);
   self.loadEntityAndOpenDialog(nextentity)
