Updatepanel + Cache Effect

[gurias81]

RenderChart Method it´s ok

 

But in postback

 

RenderChartHTML generate code ok, but chart do not display. In browser view-code, the code that appears is that of the previous method(renderchart).

 

 

There is the possibility of code being cached?

 

Thank´s

Hi,

 

Welcome to FusionCharts Forum!

 

First of all, we would like to thank you for showing interest in FusionCharts.

 

We have come up with a work around where you can use renderChart to update an update panel.

 

Please find the attached sample.

 

Here we did the following changes:

 

1. Added reference to jquery.min.js

 

2. Modified script manager to load a js script reference (JSScript.js) which will handle AJAX Client events (and render chart)

 

3. Modfied cs file to render all charts (when postback) using RenderChart (instead of RenderChartHTML)

 

4. APP_Code has a FusionCharts.cs (the source of the FusionCharts.dll) with a modification which will dispose an earlier built chart of the same id. You can compile the cs to dll.

 

Now you will find that RenderChart would work in AJAX PostBack and hence JavaScript chart would also work fine after Update Panel is updated.

 

Please give us your feedback on this.

 

Please do not hesitate to contact me if you've any queries.
