StockChart HtmlHelper Overview

The Telerik UI StockChart HtmlHelper for ASP.NET Core is a server-side wrapper for the Kendo UI StockChart widget.

The StockChart is a specialized control visualizing the price movement of any financial instrument over a certain period of time. StockCharts include extensive touch support and a navigator pane for easy browsing of extended time periods. Generally, StockCharts extend the Telerik UI Chart and share most of its features.

All of the following series types that are supported by the StockChart are also accessible from a Telerik UI Chart:

• Candlestick
• Open-high-low-close (OHLC)
• Column
• Line
• Area

Basic Configuration

The UI for ASP.NET StockChart makes Ajax requests when it is bound to a data source and has to be configured for Ajax binding.

1. Add the new action method.

   The following example demonstrates how to add a new action method which returns data to populate the StockChart.

         @(Html.Kendo().StockChart<Kendo.Mvc.Examples.Models.StockDataPoint>()
             .Name("stockChart")
             .Title("The Boeing Company (NYSE:BA)")
             .DataSource(ds => ds.Read(read => read
                 .Action("_BoeingStockData", "Home")
             ))
             .DateField("Date")
         )
   

         public class StockDataPoint
         {
             public DateTime Date { get; set; }
   
             public decimal Close { get; set; }
   
             public long Volume { get; set; }
   
             public decimal Open { get; set; }
   
             public decimal High { get; set; }
   
             public decimal Low { get; set; }
   
             public string Symbol { get; set; }
         }
   

         public IActionResult Index()
         {
             return View();
         }
   
         public IActionResult _BoeingStockData()
         {
             using (var db = GetContext())
             {
                 // Return the data as JSON.
                 return Json(
                     (from s in db.Stocks
                     where s.Symbol == "BA"
                     select new StockDataPoint
                     {
                         Date = s.Date,
                         Open = s.Open,
                         High = s.High,
                         Low = s.Low,
                         Close = s.Close,
                         Volume = s.Volume
                     }).ToList()
                 );
             }
         }
   

2. Create the data series.

   The following example demonstrates how to create the main and the navigator data series.

       @(Html.Kendo().StockChart<Kendo.Mvc.Examples.Models.StockDataPoint>()
           .Name("stockChart")
           .Title("The Boeing Company (NYSE:BA)")
           .DataSource(ds => ds.Read(read => read
               .Action("_BoeingStockData", "Home")
           ))
           .DateField("Date")
                   .Series(series => {
               series.Candlestick(s => s.Open, s => s.High, s => s.Low, s => s.Close);
           })
           .Navigator(nav => nav
               .Series(series => {
                   series.Line(s => s.Volume);
               })
           )
       )
   

Functionality and Features

The StockChart provides options for binding it to data.

Events

You can subscribe to all StockChart events.

Handling Events by Handler Name

The following example demonstrates how to subscribe to events by a handler name.

    @(Html.Kendo().StockChart(Model)
        .Name("stockChart")
        .Title("The Boeing Company (NYSE:BA)")
        .DateField("Date")
        .Series(series => {
            series.Candlestick(s => s.Open, s => s.High, s => s.Low, s => s.Close);
        })
        .Events(e => e
          .DataBound("stockChart_dataBound")
          .SeriesClick("stockChart_seriesClick")
        )
    )

    <script>
        function stockChart_dataBound(e) {
            // Handle the dataBound event.
        }

        function stockChart_seriesClick(e) {
            // Handle the seriesClick event.
        }
    </script>

Handling Events by Template Delegate

The following example demonstrates how to subscribe to events by a template delegate.

    @(Html.Kendo().StockChart(Model)
        .Name("stockChart")
        .Title("The Boeing Company (NYSE:BA)")
        .DateField("Date")
        .Series(series => {
            series.Candlestick(s => s.Open, s => s.High, s => s.Low, s => s.Close);
        })
        .Events(e => e
          .DataBound(@<text>
               function(e) {
                   //Handle the dataBound event inline.
               }
          </text>)
          .SeriesClick(@<text>
               function(e) {
                   //Handle the seriesClick event inline.
               }
          </text>)
        )
    )

Referencing Existing Instances

To reference an existing Kendo UI StockChart instance, use the jQuery.data() configuration option. Once a reference is established, use the StockChart client-side API to control its behavior.

// Place the following after the declaration of the Barcode for ASP.NET Core.
<script>
    $(function() {
        // The Name() of the StockChart is used to get its client-side instance.
        var chart = $("#stockChart").data("kendoStockChart");
    });
</script>
