Charts Disappear In Updatepanel

[jpsartre]

Hello,

 

We have a problem where our charts (v3.2.1) are disappearing on a postback when they're in a .NET UpdatePanel. So, we have our chart on a page as well as several dropdownlists which enable users to change the size of the chart, the format of chart, etc. Prior to our upgrade to 3.2.1, when a user changed their selection, there is a postback to the server and their requested formatting changes take effect. Now, after the upgrade, and without making any changes to this code, the chart disappears on the postback.

 

I noticed a couple of other unresolved posts about this. Do you have any ideas as to what I can do here?

 

Thanks,

HI,

 

Could you please check if you are using renderChartHTML at POSTBACK?

Sudipto,

 

Yes, we are using renderChartHTML on postback. It is also noteworthy again that this worked prior to our upgrade to 3.2.1. So there has been no code change other than those specified in the upgrade document and a change to the link creation.

 

Thanks,

 

Brad
