IAdHocExtension Samples¶
This article contains integration mode full-code samples for the IAdHocExtension APIs, which allow customization code to hook in the report life cycle.
Reference Izenda libraries in a New Project¶
Fig. 450 New Project
Create a new web project in Visual Studio.
Name it IAdHocExtensionSample.
Select a location (e.g. D:\Projects).
Select to create new solution.
Give the solution name IAdHocExtensionSample.
Tick the Create directory for solution check-box.
Click OK to create the project and solution.
Create a new folder for Izenda libraries D:\Projects\IAdhocExtensionSample\IAdhocExtensionSample\izendadll.
Copy the file Izenda.BI.Framework.dll from Izenda installation folder into the newly-created folder.
Open Solution Explorer, right-click References in project IAdHocExtensionSample and select Add Reference.
In Reference Manager pop-up, click Browse and select the file Izenda.BI.Framework.dll (in D:\Projects\SetupHiddenFilter).
Verify the interface by double-clicking Izenda.BI.Framework in References to open Object Browser.
Expand the nodes to Izenda.BI.Framework.CustomConfiguration and select DefaultAdHocExtension class to see the methods to override.
Similarly reference the library Izenda.BI.Core.dll and the third-party Newtonsoft.Json.dll.
Also reference System.Composition.AttributedModel.dll (https://www.nuget.org/packages/System.Composition.AttributedModel version 1.0.31) and System.Web (in Assemblies > Framework).

Add the New Library¶
- Build then copy the IAdhocExtensionSample.dll file (it can be found at D:\Projects\IAdhocExtensionSample\IAdhocExtensionSample\bin) to the Izenda Back-end API folder (at C:\inetpub\wwwroot\Izenda\API\bin).
- Restart the Izenda Back-end website.
UnitTest for the Samples¶
Add UnitTest Project¶
- Rick click Solution in Solution Explorer and select Add > New Project.
- Add a Class Library project named AdHocExtensionSampleTest.
- Reference the project IAdHocExtensionSample (Add Reference and tick IAdHocExtensionSample in Projects > Solution).
- Also reference System.Web (in Assemblies > Framework).
- Reference xUnit Library.
- Open NuGet Package Manager pop-up from Tools > NuGet Package Manager > Manage NuGet Packages for Solution…
- Click Browse tab and enter xunit in the text box to search.
- Select xunit on the left and tick the AdHocExtensionSampleTest project check-box on the right.
- Select version 2.2.0 (working at the time of writing) and click Install.
- Similarly install xunit.runner.visualstudio version 2.2.0 to AdHocExtensionSampleTest project.
Implement the UnitTests¶
Add a MockUser class to help testing:
Code for MockUser.cs:
using System.Security.Principal; namespace IAdHocExtensionSample { class MockUser: IPrincipal { private string role; public MockUser(string role) { this.role = role; } public IIdentity Identity { get; private set; } public bool IsInRole(string role) { return (role == this.role)? true : false; } } }
Right-click the default Class1.cs file in Solution Explorer and rename it to AdHocExtensionSampleTest.cs, also agree to change the class name to AdHocExtensionSampleTest when asked.
Implement the tests in xUnit.
