When I load this control into another page say "Test.aspx" and assigned some chart data. Then when my "Test.aspx" page is called and "UserControl.ascx" control is loaded, the chart  is displayed properly. but when I click on chart for zoomin it's make disappear. On bottom on page, I found there are some javascript error message display:

    "The target 'Control152$Chart152' for the callback could not be found or did not implement ICallbackEventHandler"

    I also enable zooming & scrolling property of radchart control like:

    RadChart1.ClientSettings.EnableZoom =



    RadChart1.ClientSettings.ScrollMode = Telerik.Web.UI.ChartClientScrollMode.Both
    I also tried to enable other properties like:

    Hi ajmal,

    We are unable to reproduce the problematic behavior in our local tests  -- please find attached a sample application that demonstrates loading user control dynamically that contains fully functional chart with zooming and scrolling.

    Hope this helps.

    Best wishes,
    the Telerik team

    I tried to use this to see the code example to evaluate zoom functionality, but looks like RadChart1 cannot be found even though the Telerik libraries are referenced and the object exists.

    Hello Subha,

    We are unsure what is the problem you are experiencing but the attached sample application in the previous post is runnable and works seamlessly on our end (note the control name is RadChart, while "RadChart1" is simply an identifier of a concrete instance of RadChart in this example).

    You can find online example here as well.
