DataGrid Data Export (CSV, Excel, PDF, Word)

Hi,

For exporting data from a datagrid (CSV, Excel, PDF, Word), how can I call the Oqtane module controller action or API ?

index.razor

Here's the action method under the controller:

@Sharafudeen if you create a module using the standard default template approach (ie. Module Management / Create Module ) then you will notice a Services folder in the Client project. The folder contains classes for interacting with your back-end API using HttpClient.

@sbwalker I’ve also checked the Admin panel of the Swagger APIs for my site, but no endpoints are listed. However, the datagrid data service is still working!

@sbwalker An additional point is that the ICountryService interface is placed in the MyModule.Module.Shared project, and it is implemented in two classes: CountryService in the client project and ServerCountryService in the server project. However, only the methods from the ServerCountryService class are being called, not the client project’s CountryService.

• After I commented out the highlighted code (as shown in the screenshot below), the CountryService of the client project is now being called.

• Additionally, I made sure to keep the ClientStartup CountryService scope added.

• I added the GetGridDataAsync method's code as shown in the screenshot in CountryService.

• "And finally, I added the POST method in the CountryController:

@Sharafudeen modules which are scaffolded using the default module template use a "dual service" approach, which allows them to adapt to various run-time configurations:

So if your module is using Static Blazor or it is using Interactive Blazor with Server Interactivity, then the module is running on the server and does not need to call the API Controller (an API Controller is only necessary in a true client/server environment where the client application needs to communicate with the backend API over HTTP - ie. WebAssembly or .NET MAUI)

@sbwalker The diagram you shared is explained very clearly. In my case, I can implement the file export feature within the ServerCountryService to meet my requirements.
