Not answered Charting in DotNetNuke

I have the need to create some charts and display them in DotNetNuke and found that adding a Chart control to a module throws some errors (at this point, can't remember exactly, but some popups about cannot display image, do you want to view the stack trace).

What I ended up doing as a workaround is created an ASPX page in my dnn module that will handle some querystring values and then dynamically creates a RadChart control, populates the series and all that jazz, and then calls RadChart.Save(this.Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg) (after appropriately clearing the headers and response stream and setting the content type to "image/jpeg"). The processor page is linked to an asp:Image control on the dnn module itself as the image url so it processes and shows up dandy.

What I'm wondering is if this would be "correct" usage for such a scenario or if there is a "better" way to get it working with DNN.

Has anybody got the DNN Charting working? I have DNN 4.9 with latest Q3 2008 controls.

I get radchart not display alert box and page goes into continuous loop to refresh, open alert, refresh, open alert... until I press cancel.

This is a time sucker... anyone have a solution? I've removed telerik controls, re-installed. Removed dlls from project and added fresh ones, configured web.config....

no joy

Hi Chris!!!

Thanks for ur help i tried dat. then m getting error!!

The Chart http handler is not registered. Please, manually add the following line to your Web.config httpHandlers section:
<add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2008.1.515.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />

May b my path is wrong!!

How to get exact location any Idea!!!!

I have this issue with DNN 4.9 also.

In the httpHandlers section:


<add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI,

Version=2008.2.1001.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />

The version is correct.

As per this forum I tried:


<add path=",,/,,/ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI,

Version=2008.2.1001.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />

but then it doesn't think the handler has been added to the web.config.

What else can I try?

Hi There,
I have licensed telerik controls (Telerik.Web.UI version 2009.1.527.20). I am trying to parepare chart (StackedBar100)

using telerik but its not working properly. When I check this at on devlopement machine its working but when I check this at testing server (where we publish our build) it shows following error:
Error loading RadChart image.
You may also wish to check the ASP.NET Trace for further details.
Display stack trace?

I tried to debug code at the testing server but again it works fine when I debug that. The problem is only with the build. No I have to do something extra on the testing server so that it can work fine.

I have added below lines in web.config file under httpHandler:

<

add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2009.1.527.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />

I tried "chartCompleteReports.HttpHandlerUrl = ResolveUrl("ChartImage.axd"); " also in the page_load & in method where I have written the code for binding the chart, but still its not working.

Just to let you know that we are working on web application on MS Visual Studio 2008 with dotnet framework 3.5 and language C#.net with asp.net using MS SQL SERVER 2008.

Please let me know in case of any issue/concern. I will appreicate if you will reply ASAP.

Thanks!
