Custom DataAdaptor with parameters

[Gereon Arz]

Dear Syncfusion Team,

I try to create a Custom DataManager Adaptor where I have access to the IHttpContextAccessor or can use constructor injection.

But it seems like the DataAdaptor is only allowing a parameterless constructor.

Is there a way to either create the DataAdaptor instance through injection, so that it's possible to inject as many parameters as needed or initialize the AdaptorInstance in the own code and bind the AdaptorInstance instead of the type. (e.g. AdaptorInstance="@new TestAdapter(...)")

Or maybe there is an other way to solve my problem?

Regards, 
Gereon Arz







...
<EjsDataManager AdaptorInstance="@typeof(TestAdapter)" Adaptor="Adaptors.CustomAdaptor"></EjsDataManager>

...

@code {

      public class TestAdapter : DataAdaptor

     {    

            public TestAdapter(IHttpContextAccessor HttpContextAccessor) {  }

     }

}

Hi Gereon,  

 

Thanks for contacting Syncfusion support.  

 

Query1: “so that it's possible to inject as many parameters as needed or initialize the AdaptorInstance in the own code.” 

 

Currently we do not have  support to achieve your requirement. But since it is a known requirement, we have considered it as an improvement “Provide support to inherit DataAdaptor from OwningComponentBase”. At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest. We have planned this feature for our 2019 Volume 3 Service pack 1 release (Bi-Weekly Nuget release) which is expected to be rolled out on or before 31^st October 2019. We will let you know when this feature is implemented. 

 

You can track the current status of this feature request and also communicate with us regarding the open features any time using our Feature Report page.
