Refresh time

[Erik]

I am using custom AJAX binding on a MVC grid.  I have paging enabled to show the refresh button at the bottom.  Would it be possible to retrieve the refresh time and display somewhere?  Not sure if possible inside of the grid control or somewhere else on the page.  Basically I'd like to display to the user when the grid data was last updated (both on initial load and manually initiating a refresh).

Hello Erik,

Possible solution is to append a span that will hold the last updated time in the pager container. Then update the displayed time when the requestEnd event of the data source is fired and it is of type "read". 

Handle requestEnd event:

dataSource.Events(x=> x.RequestEnd("onRequestEnd"))

Event handler logic : 

function onRequestEnd(e) {
    if (e.type === "read") {
        if ($('#lastRefresh').length) {
            $('#lastRefresh')
                .html(kendo.toString(new Date(), "g"))
        } else {
            $('<span id="lastRefresh" class="time">')
                .html(kendo.toString(new Date(), "g"))
                .insertBefore($('.k-pager-info'))
        }
    }
}

The following dojo sample illustrates the aforementioned approach:

Thanks, that was exactly what I was looking for!

Note that my pager was configured to only show the refresh button

.Pageable(pageable => pageable
            .Refresh(true)
            .Info(false)
            .Input(false)
            .Numeric(false)
            .PreviousNext(false))

 

And "k-pager-info" did not exist so I changed the insert before to:

.insertBefore($('.k-pager-refresh')
