Stimulsoft.Reports.Web designer and .NET 6 C# Web API

[diogo@forlogic.net]

Hello!

I need to integrate the Stimulsoft.Reports.Web Designer with a .NET 6 C# Web API backend.
Frontend is an Angular 14 application.

The report was loaded with no problem, but when I try to save and use the method StiAngularDesigner.GetReportObject(this), the resulting report is null.
For testing purposes I've created a new backend using the .NET 6 C# MVC Application template, and the same frontend / backend code worked fine.

Can you help me?
Thank you.

Hello!

My Web API is stateless and I think the Report Designer is trying to save each change in the server, before I really save the report file.

It only worked when I added the code " builder.Services.AddMemoryCache() " in the Startup.cs / Program.cs file.
But this application is running on multiple instances, so I cannot just use the server memory, because changes could be saved in different server instances.
I think we would need to configure an external cache, like Redis or something.

Is there an option in Designer to stop saving each change and save only when user clicks "Save" in the menu, sending the whole file?
If this option is not available, can you add in a new version?

Thank you.

Hello,

You can set the CacheMode=None

Thank you.

When I set CacheMode=None it starts showing the message "Your session has expired!"

This is how I'm setting the property CacheMode:

I've attached the source code projects.
Am I doing something wrong?

Thank you!

Hello!

I've changed the Post method in DesignController to load and return the report on every request.

I don't understand the need of doing server requests on every report change when cache is set to none, but the message "Your session has expired!" disappeared.

Now the problem is when saving the report template. User clicks "Save", the requestParams.Action is StiAction.SaveReport, but the report object is null.

Code: Select all

var report = StiAngularDesigner.GetReportObject(this); // null object

Hello.

Method StiAngularDesigner.GetReportObject(this); // null object
takes report from cache, so if you use CacheMode=None, - you must provide your own method to get report.

Hello!

So the designer is not compatible with stateless APIs?
The available options are setting up an external session/cache or provide myself a method to get the report?

Thank you.

Hello!

As a workaround I've created a new stateful ASP.NET MVC Web App.
This new webapp will run all designer requests, like loading/saving reports and other commands.

Thank you.
