Hello Sam,

Btw, what are the mode of updatePanels? I suppose it's not conditional?
Actually, I'd do the _doPostback or just implemeter ICallbackEventHandler
to process the request from one of pies

google to find the samples of usage this methods

SS> Hi All,
SS>
SS> I am creating a asp.net tool that uses 2 graphs (chartFx Pie chart
SS> [chartA]
SS> and ChartFx Barchart [chartB])
SS> The effect I'd like to get is to have the Bar chart in an update
SS> panel and
SS> when a user clicks on a segment of the Pie Voila the Barchart
SS> updates.
SS> If I populate a dropdown list with the information that populates
SS> the Pie chart then it is straight forward in using the dropdown to
SS> trigger the update panel.
SS>
SS> ChartFX Pie chart creates a client side imagemap of which I can only
SS> control the URL that each slice will redirect to e.g.
SS> "http://somesite/myTool?name=value&name2=value2" kind of thing.
SS>
SS> Could any-one take a guess at how I might be able to do such a
SS> thing.
SS>
SS> For example:
SS> do I need to put both in update panels and have chartA redirect to
SS> its URL
SS> (which would be the same page with different parameters) do some
SS> back end
SS> processing and update both panels accordingly.
SS> I know the "effect" I want and it sounds like the sort of thing Ajax
SS> should be capable of just unsure of the theory or mechanism I should
SS> be looking at.
