Hello,

We have a Kendo MVC grid in a Partial View.  The grid may have several thousand records (with 30 columns) so we went with using Ajax and server processing.  The DataSource calls a js function to return parameters. It looks like this (abbreviated version):

@(Html.Kendo().Grid<GroundWater.Models.GroundWaterSearchResult>()
          .Name("grid")
          .Columns(columns =>
          {
              columns.Bound(p => p.well_id).Title("Well ID").Width(75).Hidden(true).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Well_Name).Title("Well Name").Width(105).Locked(true);
              columns.Bound(p => p.Permit).Title("PermitNo").Width(90);
              columns.Bound(p => p.Well_Depth).Title("Well Depth").Width(64).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Measurement_By).Title("Measurement By").Width(111);
              columns.Bound(p => p.POR_Start).Title("POR Start").Width(81).Format("{0:M/d/yyyy}").HtmlAttributes(new { style = "text-align: center;" });
              columns.Bound(p => p.POR_End).Title("POR End").Width(77).Format("{0:M/d/yyyy}").HtmlAttributes(new { style = "text-align: center;" });
              columns.Bound(p => p.POR_count).Title("POR Count").Width(66).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.publication_name).Title("Publication Name").Width(93);
              columns.Bound(p => p.Receipt).Title("Receipt").Width(71);
              columns.Bound(p => p.wdid).Title("WDID").Width(65);
              columns.Bound(p => p.County).Title("County").Width(69);
              columns.Bound(p => p.basin).Title("Designated Basin").Width(91).HtmlAttributes(new { style = "text-align: right;" });
              columns.Bound(p => p.Management_District).Title("Management District").Width(91);
               columns.Bound(p => p.Modified).Title("Modified").Width(79).Format("{0:M/d/yyyy}").HtmlAttributes(new { style = "text-align: center;" });
          })
          .Pageable(pager => pager
              .PageSizes(true)
              .PageSizes(new int[] { 10, 20, 50, 100 }))
          .Sortable(sorting => sorting.AllowUnsort(false))
          .Scrollable(scroll => scroll.Height(500))
          .Filterable()
          .Resizable(resize => resize.Columns(true))
          .Reorderable(reorderable => reorderable.Columns(true))
          .ColumnMenu()
          .DataSource(dataSource => dataSource
              .Ajax()
              .Read(read => read.Action("Wells_Read", "GroundWaterSearch").Data("filterData"))
              .ServerOperation(true)
              .PageSize(50)
          )
)
<script>
    function filterData() {
        return {
            Publication: document.getElementById('publicationArea').value
            //WellName: document.getElementById('wellname').value,
            //StartDate: document.getElementById('startdate').value,
            //EndDate: document.getElementById('enddate').value,
            //ContrArea: document.getElementById('contributingarea').value,
            //WaterDistrict: document.getElementById('waterdistrict').value
            //........ up to 10 additional fields
        };
    }
</script>

And the Controller

 public ActionResult Wells_Read([DataSourceRequest]DataSourceRequest request, string Publication)
        {
            List<List<string>> criteria = new List<List<string>>();
            GetPublicationArea(Publication, criteria);
            var tempCalls = CallMgrData.GetGroundWaterLevelsResult(criteria, 20000);
            List<GroundWaterSearchResult> values = tempCalls.ResultSet.Select(x => ModelMapper.Map<CdssServiceReferences.GroundWater,     GroundWaterSearchResult>(x)).ToList();
            DataSourceResult result = values.ToDataSourceResult(request);
            return Json(result);
        }
