This document explains how a chart can be added to your Web application both at design time within Visual Studio, and programmatically.

To learn how a chart can be added to a Web page at design time within Visual Studio, refer to How to: Add a Chart to a Web Application.

Note that after a chart is first added to your web application, its Web.config file is affected. The following module is added to its XML code:

Web.config

<system.web>     <!– The following lines will be added to the system.web section.     –>     <httpModules>         <add type=”DevExpress.Web.ASPxHttpHandlerModule, DevExpress.Web.v18.2,         Version=18.2.0.0, Culture=neutral, PublicKeyToken=_”         name=”ASPxHttpHandlerModule” />     </httpModules> </system.web>     <!– And, the following - to the system.webServer section.     –> <system.webServer>     <validation validateIntegratedModeConfiguration=”false” />     <modules>         <add type=”DevExpress.Web.ASPxHttpHandlerModule, DevExpress.Web.v18.2,         Version=18.2.0.0, Culture=neutral, PublicKeyToken=_”         name=”ASPxHttpHandlerModule” />     </modules> </system.webServer>

To learn more about the ASPxHttpHandlerModule, refer to the following document: ASPxHttpHandlerModule.

To learn how a chart can be created and added to a Web page programmatically, refer to How to: Add a Chart to a Web Page (Runtime Sample)

Alternatively, a Web chart can be created entirely on the client side. A tutorial on this can be found at How to: Add a Chart to an ASPxCallbackPanel during its Callback (Runtime Sample).
