    Hi there.

    How do I get the interactive google charts to work inside a rad ajax panel? I want to be able to post back the panel and update the data for the charts and have them redraw.

    Thanks in advance.

    Hello Chris,

    I am not sure which control you are referring to, yet here are some guidelines:

    • if this is a server control (e.g., RadChart or RadHtmlChart, or another third-party ASP control), you can initiate a postback and set its server data source. This will dispose and redraw the control like any other ASP control. There are various ways to initiate a postback, for example:
      • a click on a button inside the RadAjaxPanel
      • the __doPostBack() function from MS AJAX that can simulate the click on the button
      • the RadAjaxManager's client-side API and the ajaxRequest() method.
    • if this is a client-side widget - you do not need postbacks, but rather to explore its client-side API and provide its new datasource according to its requirements.
    • If you need to use such client-side API only after a certain postback, you can register a JavaScript function call from the code-behind when needed.

    I hope this helps.
