MSCharts "No http handler was found for request type 'GET'" error

Question

Hello guys, I tried to install MSCharts on my Win2008 server. It installed without problem. Then I wrote in config.

But when I'm trying to open page with charts it returned following error. No http handler was found for request type 'GET'

Do you have any thougths about the problem?

Answer 1

Don't know anything about MSCharts, but I'd say try changing the AppPool for the app to 'Classic .NET AppPool'.

Alternatively, you may need to modify your web.config to add the handler in there. See Rick Strahl's post here.

Answer 2

Solution was in web config. IIS7 required to write handlers inside system.webserver but not in the system.web. So I just move handler and add name attribute as it became required.

Answer 3

Like Danil said, IIS7 required put the handlers in

<system.webserver>
    <handles>

Add the two lines bellow after the last add in handles

<add name="ChartImg" verb="*" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler,     System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"  />
<add name="ReportViewer" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler,Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

"Alexswi" answer is working for me and It is correct. I didn't try other answers

Answer 5

This is what you need for ASP.NET 4.0 / IIS 7.5 on Windows 7:

Your web.config must contain the following:

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


<compilation targetFramework="4.0">
 <assemblies>
  <add assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
 </assemblies>
</compilation>

<system.webServer>

<handlers>
      <add name="ChartImg" verb="*" path="ChartImg.axd"  type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"  />
    </handlers>
</system.webServer>

You also need this at the top of your aspx page:

<%@ Register Assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
    Namespace="System.Web.UI.DataVisualization.Charting" TagPrefix="asp" %>

Hope this helps
