So I have an MVC grid where I'm saving the grid settings to localstorage so that I can load the filters and the current page back to the same spot when navigating back from another action. It all works great for almost all of the columns, except for the date column (LastUpdatedDate below). The date entered is there, but you must click the Filter button again on this column to apply it, where on other columns, the filter is applied already on load. Any ideas? Page code below.

@{
    ViewBag.Title = "Vendors";
}
<h2>Vendors Index</h2>

@(Html.Kendo().Grid<VendorRegistry.Models.Vendor>()
      .Name("grid")
      .Columns(columns =>
      {
          //Excel like filtering on columns. Pulls from datasource because default shows them not in order. See Expired for default without datasource.
          columns.Bound(c => c.CompanyName).Filterable(ftb => ftb.Multi(true).Search(true).DataSource(ds => ds.Read(r => r.Action("GetCompanies", "VendorGrid"))));
          columns.Bound(c => c.Address1).Filterable(ftb => ftb.Multi(true).Search(true).DataSource(ds => ds.Read(r => r.Action("GetAddresses", "VendorGrid"))));
          columns.Bound(c => c.City).Width(110).Filterable(ftb => ftb.Multi(true).Search(true).DataSource(ds => ds.Read(r => r.Action("GetCities", "VendorGrid"))));
          columns.Bound(c => c.LastUpdatedDate);
          columns.Bound(c => c.Expired).Filterable(ftb => ftb.Multi(true));
          columns.Bound(c => c.Vetted).Filterable(ftb => ftb.Multi(true));
          columns.Template(@<text></text>)
            .ClientTemplate("<a class='k-button k-button-icontext' href='Vendors/Edit/#= ID#'><span class='k-icon k-edit'></span>Edit</a>" +
                            "<a class='k-button k-button-icontext k-grid-delete' href='Vendors/Delete/#= ID#'><span class='k-icon k-delete'></span>Delete</a>" +
                            "<a class='k-button k-button-icontext' href='Vendors/Details/#= ID#'>Details</a>")
            .Title("")
            .Width(240);
      })
      .ToolBar(tools => tools.Excel())
      .Excel(excel => excel
          .AllPages(true)
      )
      .Pageable(pager => pager
          .PageSizes(new[] { 10, 20, 30, 50, 100 }) // Default page sizes are 5, 10 and 20
      )
      .Sortable(sortable => {
          sortable.SortMode(GridSortMode.SingleColumn);
      })
      .Filterable()
      .Events(e => e.DataBound("grid_dataBound"))
      .DataSource(dataSource => dataSource
          .Ajax()
          .ServerOperation(false)
          .Model(model => model.Id(p => p.ID))
          .Read(read => read.Action("Vendors_Read", "VendorGrid"))
          .Destroy(destroy => destroy.Action("Vendors_Destroy", "VendorGrid"))
          .Sort(sort => { sort.Add(vendor => vendor.CompanyName); })
      )
      
)

@section Scripts {
    <script>
        $(document).ready(function () {
            //Load grid settings from localstorage
            var grid = $("#grid").data("kendoGrid");
            var options = localStorage["kendo-grid-options"];
            if (options) {
                grid.setOptions(JSON.parse(options));
            }
        });

        //Save grid settings so they can be reloaded later.
        function grid_dataBound() {
            var grid = $("#grid").data("kendoGrid");
            localStorage["kendo-grid-options"] = kendo.stringify(grid.getOptions());
        }
    </script>
}

Hello,

I can find out why initial sorting does not work for:

Everything else works fine; clicking on the column header does sorting. But no initial sorting!

Any ideas?

Best regards,

Manu

So I have a dropdown list that initially populates with 10 values (the most common values for race) However, when the user starts typing, it searches the entire list of values(around 900) for a match.  I didn't want load 900 values into a dropdown list so it uses server filtering and goes back to the server and searches for a match.  I can select  a race and this populates the dropdown list appropriately.  However, if i reselect the dropdownlist, it loses the value, and only shows the initial 10.  Is there a way where i can set the filter for the dropdown list to populate on click, so it will go to the server and bring back the match so it'll show that in the list and not lose its value?

Hi there,

I have encountered this problem and can not fix the filter for these two columns. 

If I use filter for these two columns: EnrolledNumber and WaitListNumber, I will get

Internet Server Error

Invalid Property or Field - 'EnrolledNumber' for type: Class

If I disabled both sortable and filter for these two columns, everything else will work fine.

How can I make the filter work and at the same time the program will not lag or become ridiculously slow?

The following is my code.

Model

View

Controller

I also get

An exception of type 'System.ArgumentException' occurred in Kendo.Mvc.dll but was not handled in user code

in Visual Studio for first time

Thank you

The RTM for ASP.NET Core is out.

There seem to be issues with the integration when calling the following method in the ConfigureServices method of the Startup class

System.TypeLoadException
Could not load type 'Microsoft.Extensions.DependencyInjection.ServiceCollectionExtensions' from assembly 'Microsoft.Extensions.DependencyInjection.Abstractions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

Hi,

I've a problem with filtering and sorting my grid. The Grid does not sort and filter my ViewModel-Properties.
