I'm trying to set an initial filter on my grid using Ajax binding:

.Filterable(filtering => filtering.Filters(f => f.Add(o => o.LotId).IsEqualTo(Model.LotId)))

However when the grid is loaded, the filter is not included in the GridCommand, i.e.: gridCommand.FilterDescriptors is empty.

If I modify the filter after initial load, the filter descriptors are send to my ajax method without problems, so it seems as if the initial configuration is not carried to the service.

Any idea when this problem will be fixed?

Your help is much appreciated!

/Dan

Hi Dan Søndergaard,

This sounds like a problem which we have already fixed in the current official release Q1 2010 SP1. However since service packs are only available for licensed users you can try the build attached in this forum thread.

Hi Atanas,

Thank you for the answer. However, it didn't solve my problem. After using the new DLL and scripts, I still get the same error.

Try and open up your Example solution.

Replace content of AjaxBinding.aspx with:

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>
<asp:Content contentPlaceHolderID="MainContent" runat="server">
<%= Html.Telerik().Grid<Order>()
        .Name("Grid")
        .Columns(columns =>
{
            columns.Bound(o => o.OrderID).Width(100);
            columns.Bound(o => o.Customer.ContactName).Width(200);
            columns.Bound(o => o.ShipAddress);
            columns.Bound(o => o.OrderDate).Format("{0:MM/dd/yyyy}").Width(120);
        })
        .DataBinding(dataBinding => dataBinding.Ajax().Select("_AjaxBinding", "Grid"))
        .Pageable()
        .Sortable()
        .Scrollable()
        .Groupable()
        .Filterable(filtering => filtering.Filters(f => f.Add(o => o.OrderID).IsEqualTo(10248)))
%>
</asp:Content>

 Run the solution, and you will see that the filter is not applied to the grid.

Hi Dan Søndergaard,

I just tested with the 2010.1.415 build and this works as expected. Please make sure you have performed the upgrade correctly. Check the assembly version in the References node.

Hi Atanas,

I'm using the MVC 2 DLL in version 2010.1.416.235. And that's the version that's in the link you send me, and I still cannot get it to work.

Thank you very much for all your help. Excellent customer service and quick response time :)

After downloading this build, I am still having a similar problem.  When I use an initial filter, the filter is executed properly when there are records returned with the filter, but if no records match, the grid will be empty for a second or so, then all the data will show up, and the grid columns are all smashed (not aligned to the header)  Have you ever seen this behavior, and is there a known fix?

Thanks,
Neil

I have the same problem.
the filter is not included in the GridCommand, so all the records is show in grid if there is no match in filters
