Problem with ClientGroupHeaderTemplate???

[Lennart]

Hej

Im trying to use the Kendo Grid for a minor project, where i want to show the column summary in the groupheader. But I cant get it to Work :-(. When i use the Groupfooter, then it works fine.

Anyone got any suggestions?

************************************************************************************
@(Html.Kendo().Grid((IEnumerable<FTEReport>)ViewBag.Test) 
     .Name("grid")
     .Columns(columns =>
{
 columns.Bound(FTEReport => FTEReport.Jan)
.ClientGroupHeaderTemplate("#=sum#");

columns.Bound(FTEReport => FTEReport.Feb)
.ClientGroupFooterTemplate("#=sum#"); 
}
 .DataSource(ds => ds.Ajax()
.Aggregates(aggregates =>
{
aggregates.Add(p => p.Jan).Sum();
aggregates.Add(p => p.Feb).Sum();
 })
.Group(g =>
{
g.Add(c => c.Allocated);
g.Add(c => c.Project);
g.Add(c => c.Department);
})
.Read(read => read.Action("Aggregates_Read", "grid"))
 )
)

Hi Lennart,

I tried to reproduce the problem locally but to no avail – everything is working as expected on our side. Could you please provide runable project where the issue is reproduced? This would help us pinpoint the exact reason for this behavior.

Hi Vladimir

Thx for your reply!

I have made a standard Kendo Project. (Full Project was to big to attach, so attach the files in the "Controllers","Models" and "Views" Folder).

Other thing Dont look like changes the Group order Works, when .Groupable() is able.

Hi Lennart,

 
From the provided information it seems that the ClientGroupFooterTemplates are not working as the Grid initially is bind to data from the ViewBag in which case the GroupFooterTemplate is used instead. In current scenario I would suggest to always load the Grid data using Ajax requests:

e.g.:

• Grid code:

  Html.Kendo().Grid<ForeignKeyColumnDemo.Models.FTEReport>()
      .Name("grid")
      .Columns(columns =>
      {

• Controller: 

  public ActionResult Aggregates_Read([DataSourceRequest] DataSourceRequest request)
  {
      List<FTEReport> test = new List<FTEReport>()
      {
          new FTEReport {Allocated="Preclinical", Project = "SYM01", Department="AD", Role="Scientists",Jan=1,Feb=1,Mar=1,Apr=1,May=1,Jun=1,Jul=1,Aug=1,Sep=1,Oct=1,Nov=1,Dec=1},
          new FTEReport {Allocated="Preclinical",Project = "SYM01", Department="AD", Role="Technicians",Jan=1,Feb=1,Mar=1,Apr=1,May=1,Jun=1,Jul=1,Aug=1,Sep=1,Oct=1,Nov=1,Dec=1},
          new FTEReport {Allocated="Preclinical",Project = "SYM01", Department="CMC", Role="Scientists",Jan=1,Feb=1,Mar=1,Apr=1,May=1,Jun=1,Jul=1,Aug=1,Sep=1,Oct=1,Nov=1,Dec=1},
          new FTEReport {Allocated="Preclinical",Project = "SYM01", Department="CMC", Role="Technicians",Jan=1,Feb=1,Mar=1,Apr=1,May=1,Jun=1,Jul=1,Aug=1,Sep=1,Oct=1,Nov=1,Dec=1},
          new FTEReport {Allocated="Preclinical",Project = "SYM04", Department="CMC", Role="Scientists",Jan=1,Feb=1,Mar=1,Apr=1,May=1,Jun=1,Jul=1,Aug=1,Sep=1,Oct=1,Nov=1,Dec=1},
          new FTEReport {Allocated="Preclinical",Project = "SYM04", Department="CMC", Role="Technicians",Jan=1,Feb=1,Mar=1,Apr=1,May=1,Jun=1,Jul=1,Aug=1,Sep=1,Oct=1,Nov=1,Dec=1}
      };
  
      return Json(test.ToDataSourceResult(request));
  }
