    I have a dock with an update panel inside of it. This update panel contains an ASP.NET Microsoft Chart Control. The Chart Control has a Click event handler. I would like to execute code from the dock level after the Chart's Click event handler has finished.

    Currently, I have a 'brute force' method of iterating through all docks on the page in Save Dock Layout and ensuring the state that I want. I would prefer to handle it on a dock-by-dock basis during this parent event handler.

    Is this possible?

    Hello Sean,

    As far as I understood you have a Chart user control inside a RadDock, and you want to execute some method (or set a property) on the parent dock, in the user control.
    My suggestion is to get a reference to the parent dock control, in the user control, and execute the desired code. The following method gets a reference to a parent dock control. The parameter passed should be a child control of a RadDock:
    private RadDock GetDock(Control ctrl)
        Control parent = ctrl.Parent;
        while (typeof(RadDock) != parent.GetType())
            parent = parent.Parent;
        RadDock dock = parent as RadDock;
        return dock;

    Hi all,

    I recently discover a solution I was happy with in this scenario:

    At the end of my chart's event I call

    RaiseBubbleEvent(sender, e);

    and then in my RadDock which is holding the chart I have:

    /// <summary>
    /// This will fire after the hosted chart's on_click event handler.
    /// Refresh all properties on the RadDock which may have changed
    /// during the on_click event.
    /// </summary>
    /// <returns>Stop bubbling the event up.</returns>
    protected override bool OnBubbleEvent(object source, EventArgs args)
        const bool CANCELEVENT = true;
        Title = string.Format("{0} - {1}", GetChartsReportName(), Chart.Title);
        SerializedChart = Chart.GetAsSerialized();
        return CANCELEVENT;

    where my RadDock is able to respond to events occurring on its content.

    Cheers :)
