I have a form with bunch of controls and a RadChart. Based on user's input I create the serieses (point chart) on the server side. Everything works fine except when the user chooses different parameter(s), the form seems to be posting the ploted data back to the server which is a problem for us. For one, it takes too long and second we get max data length error as the plotted data might exceed 4 meg.

The question is, is there any way to tell the Radchart not to post back data?
Thanks for the help.

Hi Murugan Kannan,

We would suggest you to try disabling the ViewState for the control by setting EnableViewState="false" -- this should decrease the amount of data posted to the server but you will also need to recreate the chart manually on every page load on the server-side.

Hope this helps.


Kind regards,

Okay will try this. I also moved the chart out of the form which seems to have solved the issue but not sure what other stuff it intorduced.

Of course, I am already doing that.

Thanks.
