[Solved] getKendoChart unknown

[Fit2Page]

This always worked till now:

var chart = $("#ctl00_RecordOverview_rc_heaterpower").getKendoChart();

 

Now we get:

 

service.aspx?id=7&mt=M999&mv=01&ms=00003:217 Uncaught TypeError: $(...).getKendoChart is not a function
    at init (service.aspx?id=7&mt=M999&mv=01&ms=00003:217:83)
    at HTMLDocument.<anonymous> (service.aspx?id=7&mt=M999&mv=01&ms=00003:265:29)
    at i (Telerik.Web.UI.WebResource.axd?

 

Anyone knows what is happening here?

Hello Marc,

The proper way to get the underline Kendo Chart from the ASP.NET AJAX wrapper would be to call the underline get_kendoWidget() method:

let chart = $find("<%= ColumnChart.ClientID %>");
let kendoChart = chart.get_kendoWidget();

With this:

                                let par = $("#ctl00_RecordOverview_rc_heaterpower");
                                let chart = par.get_kendoWidget();

I still get:

service.aspx?id=4&mt=M999&mv=01&ms=99999:745 Uncaught TypeError: par.get_kendoWidget is not a function

 

while my source says:

<div id="ctl00_RecordOverview_rc_heaterpower" class="RadHtmlChart RadHtmlChart_Bootstrap k-chart" style="height: 300px; width: 100%; position: relative; touch-action: none;" data-role="chart"><svg style="width: 100%; height: 100%; overflow: hidden; left: -0.428589px; top: -0.196533px;" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1"><defs><clipPath id="kdef13">ETCETERA

Hello Marc,

Since you are using the jQuery syntax to get a reference to the DOM object, you will need to access its first element (the Chart) anmd then call the get_kendoWidget() method:

let chart = $("#ColumnChart")[0].control;
let kendoChart = chart.get_kendoWidget();
