    I've got a chart, which I want to be able to dynamically set the theme for - based upon a value set in a ViewBag variable.

    I can do this if the chart is defined in JavaScript, however I can't seem to set it when the chart is defined using the helper.

    i.e.:-
    @(Html.Kendo().Chart<CMS_2013.Models.Temp_Data_Summary>()
          .Name("Chart")
          .Legend(false)
          .Title("Data in Temporary Pricing Table")
          .DataSource(dataSource => dataSource
              .Read(read => read.Action("GetSummaryChartData", "Pricing"))          
          )
          .Series(series => {
              series.Column(d => d.Records).Tooltip(true) ;
              
          })
          .CategoryAxis(axis => axis
              .Categories(model => model.Class)
          )
           
          .HtmlAttributes(new { style = "width:350px; height:250px;"})
    )
    If I do:-

    .Theme(ViewBag.SelectedTheme) - the page returns an error.  How can I do this?

    Hello,

    Although the ViewBag is dynamic, an explicit cast will still be needed in this scenario e.g.

    .Theme((string)ViewBag.SelectedTheme)
    Kind regards,

    Thanks, I did try ToString() , but not (string).

    It's working well now.
