[Solved] ClientFooterTemplate slow on empty Grid

[Lee]

I have a Grid using ClientFooterTemplate which works fine when there are rows, however on an empty Grid it takes forever to display the totals.  In fact after 5 minutes I just give up and it never displays ClientFooterTemplate.

@(Html.Telerik().Grid<GRID.ViewModels.FrozenFoodsRiskViewModel>()
     .Name("risksGrid")
     .ClientEvents(events => events.OnEdit("onEdit"))
     .Editable(editing => editing.Mode(GridEditMode.PopUp))
     .Sortable()
     .Filterable()
     .DataKeys(keys => keys.Add(r => r.RiskID))
     .ToolBar(commands => commands.Insert().ButtonType(GridButtonType.Image).HtmlAttributes(new { @title = "Add New Risk" }))
     .DataBinding(dataBinding =>
        {
            dataBinding.Ajax()
                .Select("_RisksIndex", "FrozenFoodsSection", new { policyZoneID = Model.PolicyZoneID, sectionID = Model.FrozenFoodsSectionID })
                .Update("_UpdateRisk", "FrozenFoodsSection", new { policyZoneID = Model.PolicyZoneID, sectionID = Model.FrozenFoodsSectionID })
                .Insert("_InsertRisk", "FrozenFoodsSection", new { policyZoneID = Model.PolicyZoneID, sectionID = Model.FrozenFoodsSectionID })
                .Delete("_DeleteRisk", "FrozenFoodsSection", new { policyZoneID = Model.PolicyZoneID, sectionID = Model.FrozenFoodsSectionID });
        })
     .Columns(columns =>
         {
             columns.Bound(r => r.RiskID).Hidden().ReadOnly();
             columns.Command(commands =>
                 {
                     commands.Edit().ButtonType(GridButtonType.Image).HtmlAttributes(new { @title = "Edit Risk"});
                     commands.Delete().ButtonType(GridButtonType.Image).HtmlAttributes(new { @title = "Delete Risk" });
                 }).Title("Commands").Width(110);
             columns.Bound(r => r.SumInsured).Width(100)
                 .Aggregate(aggregates => aggregates.Sum())
                 .ClientFooterTemplate("Total: <#= Sum #>");
             columns.Bound(r => r.Rate).Width(100).Format("{0:0.0000}");
             columns.Bound(r => r.Age).Width(50);
             columns.Bound(r => r.Description).Width(200);
             columns.Bound(r => r.InGuaranteePeriod).Width(100);
             columns.Bound(r => r.AgeDiscount).Width(100).Format("{0:0.0000}");
             columns.Bound(r => r.TechnicalPrice).Format("{0:0.00}").Width(100)
                 .Aggregate(aggregates => aggregates.Sum())
                 .ClientFooterTemplate("Total: <#= typeof Sum != 'undefined' ? $.telerik.formatString('{0:0.00}', Sum) : 0 #>");
         })
 )

As I say it's only an issue on an empty Grid.

Hi Lee,

Unfortunately, I'm not able to recreate the described error. Could you please verify that there are not javascript errors on the page? Also you may try the build attached to this forum thread as it does address an issue with footer aggregates. If you continue to experience difficulties, please send us a small sample in which this error can be observed.
