httphandler & postback

Should using the httphandler approach maintain the chart upon postback? I can only get it to work if I rebuild everything upon postback but this doesn't work for a cetain situation I am working with.

If this has been addressed somewhere else please direct me, I didn't find it using the search.

Thanks.

Hi mviglianco,

It may be that you need to save the chart to a session variable and load it back after postback. You'll find an example of this approach at the zooming example in the live ASP.NET demo.
