In Details window by clicking the next or previous button reaching to the last element in current page it doesn't go through the next page elements.
to deal with this I have coded to go to next page.
https://examples2.ext.net/GridPanel/...etails_Window/
 next: function () {
                //emin added

                var pgSize = App.CitiesGridIDPGTID.store.pageSize;
                var increasingIndex = this.getIndex() + 1;

                if (pgSize == increasingIndex)
                {
                    var currPage = App.CitiesGridIDPGTID.store.currentPage;
                    
                    //go next page and set increasing index to 0
                    if ((App.CitiesGridIDPGTID.store.currentPage + 1) <= App.CitiesGridIDPGTID.getPageData().pageCount)
                        App.CitiesGridIDPGTID.store.nextPage();
                    var newCurrPage = App.CitiesGridIDPGTID.store.currentPage;

                    increasingIndex = this.getIndex();
                    this.edit(increasingIndex);
                }
although it loads the next page, but it doesn't view the record with new page index. it view the previous page record.

any solution will be admired.
thanks in advance
