My grid works with aggregates (Count, Average, Max) or with grouping, but not with both.  When i try to add a group when i have any columns that display aggregates it misaligns the columns and the drag/drops column header gets stuck (see screenshot).  The only fix is to refresh the page.

[Grid Code]


    @(Html.Kendo().Grid<FullResultsView>()
        .Name(Model.GridName)
        .Columns(columns =>
        {
       columns.Bound(c => c.Code).Width(200);
        columns.Bound(c => c.FacilityIdWithName).Width(250).Title("Facility");
        columns.Bound(c => c.SampleType).Title("Sample Type").Width(120);
        columns.Bound(c => c.Result).Width(120).ClientFooterTemplate("Max:#=max#, Avg:#=average#").ClientGroupFooterTemplate("Max:#=max#, Avg:#=average#");
        columns.Bound(c => c.SequenceNumber).Title("Sequence Number").Hidden(true).Width(120);
        columns.Bound(c => c.RequiresReTest).Title("Requires Re-Test").Hidden(true).Width(120);
        })
        .ToolBar(tools => tools.Excel())
        .Scrollable(s => s.Endless(true).Height(200))
        .Filterable()
        .Sortable()
        .Groupable()
        .ColumnMenu(cm => cm.Enabled(true))
        .Resizable(resize => resize.Columns(true))
        .Reorderable(reorder => reorder.Columns(true))
        .Excel(excel => excel
        .FileName("Data Export.xlsx")
        .Filterable(true)
        .ProxyURL(Url.Action("Report_Export", "Report"))
        )
        .Editable(editable => editable.Enabled(false))
        .DataSource(Model.GridName+"dataSource").AutoBind(false)
        )

[Datasource Code]


        @(Html.Kendo().DataSource<FullLeadResultsView>()
        .Name(Model.GridName+"dataSource").Ajax(dataSource => dataSource
        .Sort(s => s.Add(sa => sa.ResultCreatedOnLocal).Descending())
        .PageSize(1000)
        .Events(events =>
        {
        events.Error("function(e){error_handler(e,'" + Model.GridName + "');}");
        })
        .Model(model =>
        {
        model.Id(m => m.Id);
        model.Field(f => f.Id).Editable(false);
        })
        .Aggregates(ag =>
        {
        ag.Add(f => f.Code).Count();
        ag.Add(f => f.Result).Average().Max();
        })
        .Read(read => read.Action("Report_Read", "Report", Model.Search).Data("onGridRead"))
        )
        )

Hi Logan,

Thank you for the code snippets, the images, and the details provided.

As I can see from the second image, the "SampleType" drag icon is still available. This could be caused by an error.

Could you please double-check the Developer Tools Console for any JavaScript errors?

The following demo represents the implementation and behavior of using aggregates along with grouping for the Kendo UI Grid:

The fastest route to getting you up and running is if you could provide a runnable, isolated, sample project. Examining this project will let us replicate the issue locally and further troubleshoot it.

Looking forward to hearing back from you.


Kind Regards,
Anton Mironov
