While running my code.
Intially I was getting No http handler was found for request type ‘GET’ error
which I solved it by referring no http handler

Hi smarx, I check it.. They asked me to change
From
<add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;" />
To
<add key="ChartImageHandler" value="storage=file;timeout=20;" />
in web config file...
But I don't have this line in my web config
I have only this for defining chart
<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" />
What should I do now....
You need to use a temporary directory that is within the folder hierarchy of your web application. In Windows Azure, you don't have access to c:\TempImages, so that is not going to work.
I created a quick sample of ASP.Net Charts working in Windows Azure here: http://code.msdn.microsoft.com/azurecharts
You can still use file storage for the temporary images:
If you don't want to download the sample, here are the steps to get it working:
TempImages
, for example).temp.txt
, or whatever) to this folder. The dev tools don't seem to publish empty directories.Set the image location of your chart to:
ImageLocation="~/TempImages/ChartPic_#SEQ(300,3)"
Add the following to appSettings in your web.config :
<add key="ChartImageHandler" value="Storage=file;Timeout=20;Url=~/tempImages/;"/>
Make sure the following is in system.web/assemblies :
<add assembly="System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
Make sure the following is in system.web/httpHandlers :
<add path="ChartImg.axd" verb="GET,HEAD" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
Make sure the following is in system.webServer/handlers
<add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
The code I uploaded to code.msdn.com should suffice as an example.
