Triggering an UpdatePanel question

Hi All,

I am creating a asp.net tool that uses 2 graphs (chartFx Pie chart [chartA]
and ChartFx Barchart [chartB])
The effect I'd like to get is to have the Bar chart in an update panel and
when a user clicks on a segment of the Pie Voila the Barchart updates.

If I populate a dropdown list with the information that populates the Pie
chart then it is straight forward in using the dropdown to trigger the update
panel.

ChartFX Pie chart creates a client side imagemap of which I can only control
the URL that each slice will redirect to e.g.
"http://somesite/myTool?name=value&name2=value2" kind of thing.

Could any-one take a guess at how I might be able to do such a thing.

For example:
do I need to put both in update panels and have chartA redirect to its URL
(which would be the same page with different parameters) do some back end
processing and update both panels accordingly.

I know the "effect" I want and it sounds like the sort of thing Ajax should
be capable of just unsure of the theory or mechanism I should be looking at.
 
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
