Changing Chart type of Chart control in ASP.NET 4

How can I change the chart type of the chart control in ASP.NET 4. I have a drop down list that contains name of all the chart types.

This is the code I came up with :

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    Chart2.Series["Series1"].ChartType =  (SeriesChartType)   
                 Enum.Parse(typeof(SeriesChartType),D开发者_如何学CropDownList1.SelectedValue);
}

You might have to call DataBind() on the chart to get it to rerender.

(If that's the problem).

Here is a sample but not using asp.net chart control, instead fusion charts.
