Using CustomAdaptor with dependency injection

Pierpaolo

Asked On October 15, 2019 10:10 PM UTC

Hello,

I'm trying to use the Grid control with Blazor in our existing application.

We have already a DAL that uses DI pattern with services and so on. I'm trying to implement server side pagination with our own CustomAdaptor and the existing services but the problem is that Adaptors.CustomAdaptor wants a parameter-less constructor and we can't pass anything.

How can I approach this scenario?

Hi Yaroslav,

Thanks for your interest with Syncfusion product.

Query: “Our company is evaluating your Blazor UI toolkit and having DI working with custom adapters is a must”

Previously we have considered this feature for our 2019 Volume 4 release which is expected to be rolled out in the month of December 2019. But considering the heavy feature request for this requirement, we have preponed the feature to our next Bi-Weekly Nuget release which will be rolled out on or before October 31^st 2019.

We will get back to you once our Bi-Weekly Nuget release gets successfully rolls out. Till then we appreciate your patience.

You could simple allow us to set the adaptor instance directly.

EjsDataManager Adaptor=@MyAdapterInstance /EjsDataManager

@code {

[Inject] public MyCustomAdaptor MyAdapterInstance {get ;set; }

}

I have the same issue as the guy above, i want to use syncfusion but this is a deal breaker. I have to be able to set the datamanager adaptor directly

Hi Micah,

Thanks for your suggestion.

Query:” You could simple allow us to set the adaptor instance directly.”

Instead of setting the adaptor instance, we have planned to implement the CustomAdaptor extending from OwningComponentBase. So that CustomAdaptor will be separate sub component of EjsDataManager (refer the below code example) instead of default AdaptorInstance. Once implemented you can pass parameters along with adaptor instance.

<EjsDataManager>

</EjsDataManager>

We have considered this requirement for our upcoming Bi-Weekly Nuget release which is expected to be roll out on or before 31^st October 2019. We appreciate your patience until then.

Regards,

Vignesh Natarajan.

So are you going to use ActivatorUtilities.CreateInstance in order to enable DI for customer adapters?

Hi Yaroslav,

Query: “So are you going to use ActivatorUtilities.CreateInstance in order to enable DI for customer adapters?”

No, we will not be creating any instance for the Dependency Injection. Custom adaptor will be provided as a Blazor component and the framework will create instance for them. The custom adaptor component will be extended from OwningComponentBase to make use of the services inside custom adaptor component as explained in below documentation.

We will get back to you once this requirement is rolled out successfully.
