    i have created a radhtmlchart dynamically using c# code , now i want to create OnClientSeriesClicked event for this chart and through this event i want to call a java script function ,
    what i am doing is that i am creating radhtmlchart using c# code and adding it to panel, this i have achived so far but now i want that when we click on the series of the chart some java scrip funtion should fire, i am not getting clear idea how to achive this .

    till now what i have done is below (just a refernce).
    create chart()
      RadHtmlChart1 = new RadHtmlChart();
                   RadHtmlChart1.OnClientSeriesClicked += new EventHandler(this.SeriesClicked);
    panel p = new panel();
    p.controls.add(RadHtmlChart1 )

       private void SeriesClicked(object sender, EventArgs e)
             ClientScript.RegisterStartupScript(this.GetType(), "print", "<script>RadHtmlChart1_SeriesClicked();</script>");

    but i am getting a runtime exception if iam doing this way ("Microsoft JScript runtime error: 'System' is undefined");

    Hello Avinash ,

    The RadHtmlChart renders entirely on the client and therefore it doesn't have server-side click event. More information on the matter is available in Known Limitations help article.

    What I can suggest in order to emulate a server-side click is that you handle the client-side click event of the chart where you can trigger an ajax request or a server-side click of a hidden button. Such an example is illustrated in this online demo.
