EjsDataManager does not display records
8 Replies
Hi Andrey,
Greetings from Syncfusion support.
Query1: “hits breakpoint, but nevertheless no records are displayed in the grid.”
We suspect that you are facing Camel Case issue in Asp.Net Core. Normally, ASP.NET Core 1.0+ framework has camel casing issues while serializing the JSON Object. If you are facing the same camel casing issue while running the sample then please use the below codes in Startup.cs file to overcome that casing issue in Application level.
In the below code, we have called the ContractResolver options under the Startup.cs file to avoid camel casing conversion during the serialization process. The is related to ASP.NET Core specifics and we suggest refer to the following article which describes how to overcome a similar issues.
Please use the code below,
|
[Startup.cs]
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc().AddNewtonsoftJson(options => {
options.SerializerSettings.ContractResolver = new DefaultContractResolver();
});
}
|
Note: WebAPI controller must return the values in form of Items and Count (refer below screenshot). Kindly ensure this in your sample.

For your convenience we have prepared a sample which can be downloaded from below
Refer our UG documentation for your reference
Query2: “I noticed that there is Adaptors.BlazorAdaptor but not found any documentation of using it”
By default, Grid will consider the Adaptor Type as BlazorAdpator if we bind the dataSource in form of List of objects or IEnumerable. So it is not necessary to define Blazor adaptor separately in EjsDataManager. Refer our UG documentation for your reference.
Please get back to us if you have further queries.
Query3: “Ideally it would be better to have an ability to call await GetData(skip, take) method on blazor control directly instead of creating api”
You can use GetJsonAsync() method of http to retrieve the entire data from WebAPI controller to bind it to Grid in the form of list of objects. But this requirement can be achieve while using Client Side Blazor or Hosted Blazor Application. So kindly confirm your Blazor Application type. Based on your confirmation, we will provide the solution / possible way to retrieve data from API controller
