If you have any issues with using the OnyakTech modules displaying charts, add the following to your web.config. This change will instruct the OnyakTech modules to use the components released with the new versions of DNN.

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
  <assemblyIdentity name="Telerik.Web.UI" publicKeyToken="121fae78165ba3d4" />
  <bindingRedirect oldVersion="2008.0.0.0-2020.0.0.0" newVersion="2010.02.0713.35" />
</dependentAssembly>
</assemblyBinding>

Depending on the version of DotNetNuke you are using, the version (in BOLD) above may be different on your site. To get the version of the Telerik.Web.UI.dll, look for the file in your sites Bin folder, right-click and select Properties to view the version. Make sure the that version and what is listed in your web.config match.

You should also check to make sure the following exist in the System.WebServer-->Handlers section of your web.config...

<add name="Telerik.Web.UI.WebResource" verb="*" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource, Telerik.Web.UI" />
<add name="Telerik.Web.UI.ChartHttpHandler" verb="*" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Culture=neutral, PublicKeyToken=121fae78165ba3d4" />

If your using the new OnyakTech Charts module or the Native Charts option in the ReZults module, then you will need to make the following web.config changes to see the charts.  Ignore the information above, that is for older charts.


Chart Setup: Complete the following web.config changes if you don't see charts on this page.

 In my case also following part is required:

 <appSettings>

    <add key="ChartImageHandler" value="storage=file;timeout=20;" />

 </appSettings>

 I have just installed the ReZults module on DNN 6.2.1 and created a small survey. The survey works fine, but when I get to completion page, I received this error:

Unknown server tag 'asp:chart'.

but no error in the event log.

I then followed the instructions in Chris' latest post and added the 3 lines in the relevant sections of my web.config module.

This resulted in an exception, even after I added D.Mascaretti's app settings:

A critical error has occurred. Request failed.

Anyone got a suggestion?

Thanks

Phil
