Custom Data Source and Component Extension Questions

[Johnadam]

Hello,

We are currently using **Stimulsoft.Dashboards.Web (version 2026.2.2)** within our ASP.NET MVC application.

To meet some specific business requirements, we developed a custom data source by implementing the `StiDataStoreAdapterService` class. So far, this implementation has been working exactly as expected.

We now need to introduce additional functionality, which raises several questions regarding the framework's extensibility.

### 1. Creating an Advanced Custom Data Source Type

We would like to build a new custom data source type that provides more advanced capabilities than our current implementation.

In particular, we need the data source to support a **custom properties panel** containing user-defined properties. These custom properties should be fully accessible and configurable directly from the **Dashboards.Web Designer**.

Could you please advise whether this type of customization is supported and, if so, what would be the recommended approach for implementing it?

Hello,

It can be implemented only via source code.

Thank you.
