ASP.NET Core StockChart Overview

The Telerik UI StockChart TagHelper and HtmlHelper for ASP.NET Core are server-side wrappers for the Kendo UI StockChart component.

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.

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")
         )
   

         <kendo-stockchart name="stockChart"
                 date-field="Date">
             <chart-title text=" The Boeing Company (NYSE:BA)"></chart-title>
             <datasource custom-type="aspnetmvc-ajax"
                     server-paging="true"
                     server-filtering="true"
                     server-grouping="true">
                 <transport>
                     <read  url="@Url.Action("_BoeingStockData", "Financial")"/>
                 </transport>
                  <schema>
                 <model>
                     <fields>
                         <field name="Date" type="date"></field>
                         <field name="Close" type="number"></field>
                         <field name="Volume" type="number"></field>
                         <field name="Open" type="number"></field>
                         <field name="High" type="number"></field>
                         <field name="Low" type="number"></field>
                         <field name="Symbol" type="string"></field>
                     </fields>
                 </model>
             </schema>
             </datasource>
         </kendo-stockchart>
   

         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()
                 );
             }
         }
   

         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; }
         }
   

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);
               })
           )
       )
   

       <kendo-stockchart name="stockChart"
               date-field="Date">
           <chart-title text=" The Boeing Company (NYSE:BA)"></chart-title>
           <datasource custom-type="aspnetmvc-ajax"
                   server-paging="true"
                   server-filtering="true"
                   server-grouping="true">
               <transport>
                   <read  url="@Url.Action("_BoeingStockData", "Financial")"/>
               </transport>
                <schema>
               <model>
                   <fields>
                       <field name="Date" type="date"></field>
                       <field name="Close" type="number"></field>
                       <field name="Volume" type="number"></field>
                       <field name="Open" type="number"></field>
                       <field name="High" type="number"></field>
                       <field name="Low" type="number"></field>
                       <field name="Symbol" type="string"></field>
                   </fields>
               </model>
           </schema>
           </datasource>
           <series>
               <series-item type="ChartSeriesType.Candlestick" open-field="Open" high-field="High" low-field="Low" close-field="Close"></series-item>
           </series>
           <navigator>
           <navigator-series>
                   <series-item type="ChartSeriesType.Line" field="Volume"></series-item>
               </navigator-series>
               <select from="new DateTime(2009,02,05)" to="new DateTime(2011,10,07)"></select>
           </navigator>
       </kendo-stockchart>
