Deleting last remaining row on kendo grid on the last page does not go to the previous page

[Regis]

See video:
http://screencast.com/t/pHdDhSg26X

It also happens if for example you are on the the 3rd page and you set the grid with
$('grid').data().kendoGrid.dataSource.data([the data])

If the data has less rows then the current page, example, new data 10 rows and you are on page 3 of a grid with 5 rows per page, it says on page 3, which is blank because you have only 10 rows.


Using latest as you can see on the video.

Hi Regis,

 
Please note that current behavior is correct - the grid currently doesn't check if the current grid view contains no records to change the page and you should implement it using custom code. For example you can use the dataBound event of the dataSource to check if current view contains no records to move to the previous page.

Also I would suggest to share your idea at Kendo UserVoice to allow other users vote for it. Most voted ideas are included in next KendoUI releases.

e.g.:

function onDataBound(e) {
    if (this.dataSource.view().length == 0) {
        var currentPage = this.dataSource.page();
        if (currentPage > 1) {
            this.dataSource.page(currentPage - 1);
        }
    }
}

I too am confident thousands of my users would find this default behavior to be confusing. It's not the typical behavior of a paged collection in any application I've ever used. Typically when the last item is deleted from a page, that page ceases to exist. Personally I would like to see this built-in.

Thanks for posting with the video, Regis and thank you for the code example, Vladimir.
