Integrate into an MVC Application

Steps :

Create an MVC (min version 2.0) project in Visual Studio.
Install FusionCharts.ExcelExport.MVC using one of the two methods given below:
- Method 1: Through Nuget Package Manager:
  - Search for the package in the Nuget repository.
  - Click Install.
- Method 2: Through the Nuget command line, execute the command given below:

$ Install-Package FusionCharts.ExcelExport.MVC -Version 1.0.0-beta

Add the code given below to the Global.asax class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
// Step 1: Import dependencies
using FusionCharts.ExportServerMVC.Register;

namespace FusionExcelExportServer
{
    public class FusionExcelExport : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            // Step 2: Register export route
            (new ExportMVCRegistrar()).RegisterRoutes(RouteTable.Routes);        
        }

        protected void Application_BeginRequest(Object sender, EventArgs e)
        {
            // Step 3: Handle pre-flight request
            if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
            {
                HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", HttpContext.Current.Request.Headers["Access-Control-Request-Headers"]);
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
                HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
                HttpContext.Current.Response.End();
            }
        }
    }
}

The above code:

Imports module dependency.
Registers the export route handler in the Application_Start method of the Global.asax class.
Handles the pre-flight OPTIONS response headers.
The method signature for ExportMVCRegistrar.RegisterRoutes is:

ExportMVCRegistrar RegisterRoutes(RouteCollection routes, [string routeURL = "api/v1.0/export"])`

The routeURL is optional and the default URL is api/v1.0/export. This is the URL of the export endpoint and should be set as exportExcelHandler field in chart config (client-side setup). For e.g., default endpoint URL will be http://yourURL.com/api/v1.0/export.

To disable incoming request validation, add the code given below to the web.config file:

<configuration>
    <system.web>
    <!-- 
    Add these configurations to your existing system.web.
    If the mentioned tags are already present in your web.config, only add the missing attribute values for that tag.
    -->
    <httpRuntime requestValidationMode="2.0"/>
    <pages>
        <namespaces>
            <add namespace="System.Web.Mvc"/>
            <add namespace="System.Web.Mvc.Ajax"/>
            <add namespace="System.Web.Mvc.Html"/>
            <add namespace="System.Web.Routing"/>
        </namespaces>
    </pages>
    </system.web>
</configuration>

Build and run the application.

Integrate into a simple ASP.Net application

Steps:

Create a simple web application from an empty template or use your existing project in Visual Studio.
Install FusionCharts.ExcelExport.SimpleASPX using one of the two methods given below:
Method 1: Through Nuget Package Manager
- Search for the package in the Nuget repository.
- Click Install.
Method 2: Through the Nuget command line, execute the command given below: $ Install-Package FusionCharts.ExcelExport.SimpleASPX -Version 1.0.0-beta
In the web.config file, add <httpRuntime requestValidationMode="2.0" /> under the <system.web> configuration, as shown below:

<configuration>
    <system.web>
    <!-- 
    Add these configurations to your existing system.web.
    If the mentioned tags are already present in your web.config, only add the missing attribute values for that tag.
    -->
    <httpRuntime requestValidationMode="2.0"/>
    <pages>
        <namespaces>
            <add namespace="System.Web.Mvc"/>
            <add namespace="System.Web.Mvc.Ajax"/>
            <add namespace="System.Web.Mvc.Html"/>
            <add namespace="System.Web.Routing"/>
        </namespaces>
    </pages>
    </system.web>
</configuration>

By default FCExcelExport.aspx will be located in the root directory, so your default post request will be handled by https://yourURL.com//FCExcelExport.aspx .
For a custom path of Excel export, save the file FCExcelExport.aspx in your desired location and post all your requests to that path. E.g. https://yourURL.com/ < file location >/FCExcelExport.aspx.
Build and run the application.
