Questions on Kendo UI for jQuery Forum

I am trying to display a simple chart from remote data, but I'm having trouble with aggregates. For a table of people, I'd like to see a bar chart that shows the number of people in each role. I think the bottom-line question is, "where are the aggregates calculated?" Does the framework calculate them on the client side after the data has been returned from the server? In my ASPNet MVC controller, I can see the expected Kendo.Mvc.GroupDescriptor list and the Kendo.Mvc.IFilterDescriptor list populated correctly, but the Kendo.Mvc.AggregateDescriptor list is empty. Should it be? Also, the AggregateFunctions collection in the GroupDescriptor is also empty. Please advise.

var myDataSource = new kendo.data.DataSource({
       transport: {
           prefix: "",
           read: {
               url: "/Team/TeamMembers",
               type: "POST"
           }
       },
       group: {
           field: "personRole",
           aggregates: [{
               field: "personId",
               aggregate: "count"
           }]
       }
}

Foreign Key Column doesn't render a DropDownList

Hi, I have been in this problem for too long. The Foreign Key Column doesn't render a DropDownList, instead of that, it renders an <input>. I don't know why. I've been through many forums but without success. Please help me. I have the following structure.

The model and view:

public class ProcesoEvaluacionDTO

{

[ScaffoldColumn(false)]

public int ID { get; set; }

[Required]

[MaxLength(200)]

public string Nombre { get; set; }

[DisplayName("Fecha de cierre a evaluadores")]

[Required]

[DataType(DataType.Date), DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]

public string FechaCierre { get; set; }

[Required]

[UIHint("GridForeignKey")]

[DisplayName("Autorizado por")]

public int AutorizadorID { get; set; }

public ProcesoEvaluacionDTO() { }

}

public class ColaboradorDTO

{

public string NombreCompleto { get; set; }

public int ID { get; set; }

public ColaboradorDTO() { }

}

@{

IList<ColaboradorDTO> colaboradores = ViewBag.colaboradores;

SelectList lista = new SelectList(colaboradores, "ID", "NombreCompleto");

}

@(Html.Kendo().Grid<ProcesoEvaluacionDTO>()

.Name("ProcesosDeEvaluacionGrid")

.Columns(columns =>

{

columns.ForeignKey((p => p.AutorizadorID), lista);

columns.Bound(p => p.Nombre);

columns.Bound(p => p.FechaCierre);

columns.Command(command => {

command.Edit();

command.Destroy();

}).Width(300);

}

)

.ToolBar(toolbar => toolbar.Create())

.Editable(editable => editable

.Mode(GridEditMode.PopUp)

)

.Pageable(paper => paper.Refresh(true))

.Filterable()

.Sortable()

.Scrollable(w => w.Height(330))

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(20)

.ServerOperation(false)

.Events(events => events.Error("error_handler"))

.Model(model => { model.Id(p => p.ID); })

.Create(update => update.Action("EditingInline_Create", "ProcesoEvaluacion"))

.Read(read => read.Action("EditingInline_Read", "ProcesoEvaluacion"))

.Update(update => update.Action("EditingInline_Update", "ProcesoEvaluacion"))

.Destroy(update => update.Action("EditingInline_Destroy", "ProcesoEvaluacion"))

)

Also, GridForeignKey.cshtml is in the correct place ~/Views/Shadres/EditorTemplates. I really don't know why an <input> appears. I've even tried to write my own custom editor template but I've got the same error. Help please.

[Solved] Get Partial Checked item

Hi, I need to send back checked items in a hierarchical tree view and the state they're in. The state has to have 3 values, checked, unchecked and the "partial" check where only some children are checked (and the checkbox itself is "filled").

How do I get this state? I see no class, or anything that tells me it's partial (short of looking through it's child tree and looking for checked items, which I don't want to do).

Missing Popup in TypeScript definition

For the life of me, I cannot find kendoPopup() in the TypeScript definition file as either an extension to JQuery or as a class widget in kendo.ui.

Is this by design or an oversight?

Tooltip Problem - dataitem member undefined

It is pretty straight forward, there are plenty of references to using:

@(Html.Kendo().Chart(Model.oeeList)

.Name("widget-oee-breakdown")

.Theme("black")

.DataSource(ds => ds

.Group(group => group.Add(model => model.resp_id))

)

.Series(series =>

{

series.Column <double

?, string> (model => model.total, categoryExpression: model => model.area_name).Color("White").Name("Downtime").Labels(labels => labels.Visible(false).Format("{0:n2}")).Stack(true);

})

.ChartArea(ca => ca

.Background("transparent")

)

.CategoryAxis(axis => axis

.MajorGridLines(lines => lines.Visible(false))

.Labels(model => model.Rotation(90))

)

.Legend(legend => legend

.Visible(false)

)

.ValueAxis(axis => axis

.Numeric()

.Max(100)

.Line(line => line.Visible(false))

.MajorGridLines(lines => lines.Visible(false))

.Labels(false)

)

.Tooltip(tooltip => tooltip

.Visible(true)

.Template("#= dataItem.resp_name #: #= kendo.format('{0:n2}', value) #")

)

)

In this forum as well as others. "dataItem" doesn't return as undefined, but any member I specify does. In the example above I am using resp_name, which is in the data. Even if I try to use resp_id, which is what shows if I use series.name instead. Basically, anything I put after dataItem returns as undefined. Any ideas??

[Solved] Adding an average line to an existing column chart

I've got a column chart with a single series. I am trying to add an average line to it. So, let's say the column chart has 5 data points [10, 20, 30, 20, 30] and shows 5 columns on the chart. The average is 22. Do I really need to have the average data be [22, 22, 22, 22, 22], which will put a circle for each data point on the line? Ideally, I'd like a single horizontal line across the chart without any data points showing up (while still having the data points on the columns show up so I can do hover). Hmmm, it would be nice to still have the hoverable capability on the average line so the user can see the exact value.
What are my options here?
Thanks,

[Solved] Filter persists on reload of data

Hi,
Using the Kendo grid in Single Page Application using MVVM.
The filtering is only at client side, so when the user filters once on a column (say it has only one row) and then next reloads new data to the grid -the filter persists on the grid. It should ideally clear the filter off and reload fresh data without filters.
How is that possible (how to enforce it since it is not happening as expected)
