Hi Simon,  

  

Thanks for contacting Syncfusion support.  

  

The problem you are currently facing is the known issue and that will occur only when the dashboard sample is created with the reference of very first release of the Syncfusion Dashboard Platform SDK.  

Initially we have provided the support to embed the ejDashboardViewer into the ASP.NET MVC platform under EJ().  

Later we are having the requirement that integrating the ejDashboardViewer along with the Syncfusion ejControls, here both the wrapper library should contains the EJ() component. At that case we are facing the conflict with the ambiguous reference that you are currently facing.  

  

So we have decided to the provide the separate wrapper library for ejDashboardViewer at the case while integrating with the ejControls named Syncfusion.EJ.DashboardViewer.Mvc which should call the ejDashboardViewer via EJDashboard() instead of Syncfusion.EJ.DashboardViewer’s EJ()  

In the meantime we are providing the support for the backward compatibility via the library  Syncfusion.EJ.DashboardViewer (On the usage of ejDashboardViewer alone).  

  

Please find the following changes regarding the issue you are currently facing.  

  

Dashboard Platform Version	up to 2.3.032	3.1.0.113 and later
Wrapper DLL reference	Syncfusion.EJ.DashboardViewer	Syncfusion.EJ.DashboardViewer.Mvc
Syntax	@Html.EJ().DashboardViewer	@Html.EJDashboard().DashboardViewer

  

You can call the ejdashboardViewer along with the ejControls like below example by using the Syncfusion.EJ.DashboardViewer.Mvc for ejDashboardViewer  

  

  

  

Please find the Syncfusion.EJ.DashboardViewer.Mvc  wrapper dll from the following Synfusion Dashboard Platform SDK installed location  

%LocalAppData%\Syncfusion\Dashboard Platform SDK\Getting Started Samples\Common\Precompiled Assemblies\Syncfusion.EJ.DashboardViewer.Mvc\  

  

Or you can get it from the following nuget  https://www.nuget.org/packages/Syncfusion.EJ.DashboardViewer.Mvc/  

 

Also you can refer the Getting started sample from the installed location itself.  

%LocalAppData%\Syncfusion\Dashboard Platform SDK\Getting Started Samples\ASP.NET MVC\LocalEmbeddedDashboard

Hello,

 

Farveen sulthana T,

Thanks for your response.

We managed to work around the embed dashboard using Service DLL by using a lower version 15 other than current version 17.

Now when i run the application in the hosted IIS server it doesn't run the dashboard, but if i run the application from the development environment IDE, the dashboard loads well.

Application in IDE visual studio 2017 where it loads the dashboard well using embed dashboard with DLL as a service

Application in Hosted Environment (IIS Server) where it refuses to load the dashboard using embed dashboard with DLL as a service

Thanks again 

please advise 

Simon
