Question

http://msdn.microsoft.com/en-us/library/system.web.ui.datavisualization.charting.chart.click.aspx

The event handler:

protected void Chart1_Click(object sender, ImageMapEventArgs e)
{
        //stuff
}

I would like to raise this event manually.

public ActionResult HistoricalDrillDown(int reportID, string postBackValue)
{
    string sessionKey = string.Format("HistoricalReport: {0}", reportID);
    LineChart lineChart = (LineChart)Session[sessionKey];

    ImageMapEventArgs imageMapEventArgs = new ImageMapEventArgs(postBackValue);
    //Raise lineChart.Click() using ImageMapEventArgs
}

I feel like I’m pretty close — I’m just not sure how to broadcast an event using ImageMapEventArgs. Anyone?

Thanks

You should move your code to a separate method and call that method from the handler.

Calling event handlers directly is bad practice.
