[Solved] Paging on Ajax Grid

[Jamie]

Is there a way to manually set paging on a grid?  I'm using onDataBinding to call an ajax function, which then calls grid.dataBind with the results.  The controller only returns the number of results that can be displayed on one page of the grid, as json results can't be IQueryable.  And the paging always says 0 of 0 results.

So, is there a way to say "the grid has 5000 records, and you're on page 6" programmatically?  Or should I just hide the paging control and roll my own?

If it helps at all, here's the function that gets called from onLoad and onDataBinding:

function populateGrid(entity, searchColumn, searchText) {

    var grid = $('#' + entity + '_grid').data('tGrid');

    var searchMethod = 'gridlist';

    $('.t-status .t-icon', grid.element).addClass('t-loading');

    $.ajax({

        url: '/json/' + entity + '/' + searchMethod + '?',

        data: { field: searchColumn, value: searchText },

        error: function (xhr, status) {

            alert(status);

        },

        success: function (data) {

            grid.dataBind(data);

            $('.t-status .t-icon', grid.element).removeClass('t-loading');

        }

    });

}

Hello Jamie,

You can try updating the currentPage and total fields of the grid before calling the dataBind method:

grid.currentPage = 2;

grid.total = 100;

grid.dataBind(data);

I hope this helps,

That's perfect.  Just one more question... how I do I access the paging controls, so when they click forward or a page number, I can capture that on the client?  Like onPaging or something?

If you want to point me in the direction of the api I'd be happy to research on my own. I'm just having a really hard time finding any documentation on the MVC api...

Hello Jamie,

 You can use the onDataBinding client event and access the currentPage field from there. It should be properly updated.

Hi Atanas,

grid.currentPage = 2;

grid.total = 100;

grid.dataBind(data);

The above code updates the paging parameters successfully but it always show the data of currentPage = 1. Any idea why this could be happening?

Thx in advance.
