I was able to successfully get the ChartImg.axd handler to work in an MVC 2 application; however the page’s call to it was resulting in an HTTP 404 error. (I found this using Fiddler.)

It turns out the page was trying to access the handler from /MyController/ChartImg.axd instead of /ChartImg.axd (from the root).

I was able to fix the problem by adding this line to my Global.asax.cs file:

routes.IgnoreRoute(“{controller}/{resource}.axd/{*pathInfo}”);

Also don’t forget to add the routing rules to global.asax to prevent the MVC engine from intercepting the URLS for the Chart httpHandler.

routes.IgnoreRoute(“{controller}/ChartImg.axd”);
routes.IgnoreRoute(“{controller}/{action}/ChartImg.axd”);

If you place the chart control is a view; then the URL for the chart.axd becomes virtualDirectory/ControllerName/MethodName/Chart.axd which of course “conflicts” with the MVC namespace – the result is “broken/missing” images. Unless you add the fix.

I get this: Session state has created a session id, but cannot save it because the response was already flushed by the application.

I am using MS charts with a SQL data source and all is working well. The only problem I am currently am having is if my data source returns no data then my chart is just the background colour white. Is there a way of changing this to display a graphic?

Sorry Robert,
I am not able to put html code in comments. Use design time code in partial view and below it, use inline code to generate graph. Last 2 lines are from ur solution B

HtmlTextWriter writer = new HtmlTextWriter(Page.Response.Output);
Chart2.RenderControl(writer);

Let me know whether it’s useful for u or not. Don’t forget about javascript I have included in my previous comments.

Hi Robert, I am not able to put html in comments. So I have commented the html code. Uncomment it for use.
