[Solved] Different behavior between v2011.1.414 vs v2010.3.1318

[Alexandre Jobin]

Hi!

If you are in ajax mode and you want to rebind your grid by changing a parameter like this:

$('#grid').data('tGrid').rebind({ year: 2001 });

and then you change the page or just click the refresh button, you will not have the same behavior depending of the version that you use.

With version 2010.3.1318, each ajax request after the rebind will keep the new param value (year = 2001)
With version 2011.1.414, each ajax request after the rebind will not keep the new param. It will use the one that have been used on the initialization of the grid.

Here's the syntax of my grid:

Html.Telerik().Grid<MTO.GIPI.Web.Controllers.Besoins.ViewModels.BesoinIndexGridViewModel>()
.Name("gridBesoin")
.BindTo(Model.BesoinGridData.Data)
.DataKeys(keys => keys.Add(m => m.PublicationId))
.Columns(column =>
    {
        column.Bound(a => a.Intervenant);
        column.Bound(a => a.Publication);
        column.Bound(a => a.QuantiteBesoin);
        column.Bound(a => a.QuantitePremiereLivraison);
    })
.DataBinding(bind => bind.Ajax().Select("GetBesoinIndexGridData", "Besoins", new { searchKeyword = "", year = Model.AnneeInventaire }))
.Groupable(x =>
{
    x.Enabled(true);
    x.Groups(group => group.Add(c => c.Intervenant));
})
.Pageable(page =>
{
    page.PageSize(10);
    page.Total(Model.BesoinGridData.Total);
})
.Scrollable(scroll => scroll.Height(250))
.EnableCustomBinding(true)
.Render();

I'm facing the same issue! Hope we get a solution soon!

Hi,

 This has been noted in the changes and backwards compatibility help topic. We have explained what has changed and how to implement a workaround.

All the best,

Managed to solve this issue by doing the following:

1. Changed the grid ajax binding registration to not pass default parameters (so only referencing the method and controller)
.DataBinding(dataBinding => dataBinding.Ajax()
                        .Select("_AjaxBindingActivityReport","Report"))

2. Storing the filter parameters that I want persisted into a  javascript variable within the function that calls grid.rebind
 
query = qType;

3. Added the code outlined in the work around to the onDataBinding function

args.data = $.extend(args.data, { queryType: query });

Seems to be working!

Thanks

it work with the workaround but not completly. Take this scenario with the workaround:

Grid

• grouped on a column, the .rebind() with the dataBinding(args) will keep it grouped
• sorted on a column, the .rebind() with the dataBinding(args) will not keep it sorted
• filtered on a column, i havent tested it
