Highlight the hovered row in Gantt


Product Version 2023.2.829

How can I change the color of the hovered row in the Telerik UI for UI for ASP.NET Core Gantt ?


The example below relies on the following key steps:

  1. Handle the "mouseenter" Event of a cell in the Grid.
  2. Remove previously assigned "custom" class.
  3. Get the index of the hovered row.
  4. Add the "custom" class to the current target.
  5. Add the "custom" class to the corresponding row(using the index from step 3) in the right calendar part of the Gantt.
  6. Add color to the "custom" class.
  7. Here is an example of the code:

       @using Kendo.Mvc.Examples.Models.Gantt;
       @(Html.Kendo().Gantt<TaskViewModel, DependencyViewModel>()
           .Columns(columns =>
               columns.Bound(c => c.TaskID).Title("ID").Width(50);
               columns.Bound(c => c.Title).Editable(true).Sortable(true);
               columns.Group(g =>
                   g.Bound(c => c.Start).Width(100).Editable(true).Sortable(true);
                   g.Bound(c => c.End).Width(100).Editable(true).Sortable(true);
           .Views(views =>
               views.WeekView(weekView => weekView.Selected(true));
           .DataSource(d => d
               .Model(m =>
                   m.Id(f => f.TaskID);
                   m.ParentId(f => f.ParentID);
                   m.Field(f => f.Expanded).DefaultValue(true);
               .Read("Basic_Usage_ReadTasks", "Gantt")
               .Destroy("Basic_Usage_DestroyTask", "Gantt")
               .Update(update => update.Action("Basic_Usage_UpdateTask", "Gantt").Data("onUpdateCreate"))
               .Create(create => create.Action("Basic_Usage_CreateTask", "Gantt").Data("onUpdateCreate"))
           .DependenciesDataSource(d => d
               .Model(m =>
                   m.Id(f => f.DependencyID);
                   m.PredecessorId(f => f.PredecessorID);
                   m.SuccessorId(f => f.SuccessorID);
               .Read("Basic_Usage_ReadDependencies", "Gantt")
               .Create("Basic_Usage_CreateDependency", "Gantt")
               .Destroy("Basic_Usage_DestroyDependency", "Gantt")
            var gantt = $("#gantt").data("kendoGantt");
            gantt.wrapper.on("mouseenter", "[role='gridcell']", function(e) {       
              var index = $(;
              $('.k-gantt-tasks tr').eq(index).addClass('custom');
          background-color: yellow !important
