DataSource Schema "data" property

[Andrew]

I'm initialising a chart in MVC razor syntax, and am unable to find a way of specifying the schema of returned data from an AJAX bound DataSource, as specified in the DataSource documentation:

schema: {
    data: "results" // twitter's response is { "results": [ /* results */ ] }
}

As I'm not autobinding my chart, I've tried setting the schema property in JS before calling the read() method on the DataSource , but this doesn't seem to make any difference:

chart.dataSource.options = { schema: { data: "results" } };

Is this functionality possible using the ASP.NET wrappers?

Hello,

The DataSource schema will be generated automatically from the specified model class. You can specify the model class as a generic argument:

    @(Html.Kendo().Chart<ElectricityProduction>()
         .Name("chart")
         .DataSource(ds => ds.Read(read => read.Action("_Read", "Home")))
         ...

I hope this helps.

All the best,

I have the same question and can't rely on the auto-bind.  How would I map the data property to Mymodel.ChildCollection?

Hello Orrin,

Setting the schema explicitly is not supported via the MVC wrappers. The raw JS API might make more sense in your case.

Do you mind sharing a bit more details about your setup?

Hi,

Just a quick follow-up. You can also try passing the collection to the constructor:

    @(Html.Kendo().Chart(Mymodel.ChildCollection)

I hope this helps.

Okay, thanks.  I had a complex model I wanted to bind to my form (parent with child collection), which I've since learned KendoUI doesn't support.  I've broken my view model into separate models for each level of the hierarchy as suggested in other posts.
