Possible to have dock listen for content event?

[Sean]

Hi,

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?

Thanks

Sean

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 :)
