Putting header in DataManager


Hi,

I m using an api service method to get the datasource for an ejGrid to do virtual scrolling

"getReportData() {
    this.gridData = new ej.DataManager({
      url: 'http://localhost:43317/api/WebReports/GetReportData/'+ this.reportId,
      adaptor: new ej.UrlAdaptor()
      ,crossDomain: true
    });"

" public IEnumerable<dynamic> GetReportData( int id, DataManager dm)
        {
               ...
               return res;
        }"
and i m putting "[EnableCors(origins: "http://localhost:3000", headers: "*", methods: "*")]" above the controller to enable cors.

but this error appears

"XMLHttpRequest cannot load http://localhost:43317/api/WebReports/GetReportData/61. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. The response had HTTP status code 405."

i think the solution is putting a header at the request of the datamanager, but i don't know how.

Please advise.

Hi Dina Abdelbary, 
 
Thanks for contacting Syncfusion support. 
 
We analyzed the code examples that you have shared. If you would like to fetch data from a custom action of controller, then we suggest you to use without localhost URL of the DataManager.  
 
Please refer to the below online documentation in which we have explained in detail on the various data binding concepts help link: https://help.syncfusion.com/js/datamanager/data-adaptors#url-adaptor  
 
We have prepared a grid sample with URL adaptor binding, which can be downloaded from the below location.  


Regards,  
Karthikeyan V.

Hi,

The demo you have attached uses jquery not angular2 !! and also my question uses web api service, and the attached one uses a normal Controller not ApiController,
what do you mean about "use without localhost URL of the DataManager", so what if i wanna call a web api service method??
and also i asked about how to set the header at the request of the datamanager

Regards,

hi 

we were having this same issue , and trying to apply a fix for days now. 


using below line for get data

 this.data = new DataManager({

          url: ...some_Uri...,

         crossDomain:true,

         adaptor: new UrlAdaptor });

we wanted to pass the same Uri with the headers. 

thank you.
