SfDatamanager seems to work but no data in datagrid

[John van Nuland]

I have this code:

And when the page is loaded the Get Request is fired but, the data is not shown in the Grid.

Please help me I don't understand why the data does not show in the SfGrid??

    <SfGrid TValue="UnitMappingDtoForViewing" AllowResizing="true" EnableHover="true" AllowPaging="true" AllowSorting="true" Toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Cancel", "Update" })">
        <SfDataManager Url="@UnitMappingUrl" Adaptor="Adaptors.JsonAdaptor"></SfDataManager>
        <GridEditSettings AllowAdding="true" AllowDeleting="true" AllowEditing="true" Mode="EditMode.Normal"></GridEditSettings>
        <GridPageSettings PageSize="10"></GridPageSettings>
        <GridColumns>
            <GridColumn Field="Id" HeaderText="ID" IsPrimaryKey="true" IsIdentity="true" AutoFit="true"></GridColumn>
            <GridColumn Field="PLMUnit" HeaderText="PLM/PDM Unit" AutoFit="true"></GridColumn>
            <GridColumn Field="IsahUnit" HeaderText="Isah Unit" AutoFit="true"></GridColumn>
            @*@foreach (var prop in typeof(UnitMappingDtoForViewing).GetProperties())
                {
                    <GridColumn Field="@prop.Name" AutoFit="true"></GridColumn>
                }*@
        </GridColumns>
    </SfGrid>

code behind:

namespace EngineeringAPIWebsite.Pages
{
    public class UnitMappingListBase :ComponentBase
    {
        public class UnitMappingDtoForViewing
        {
            public Int32 Id { get; set; }
            public string PLMUnit { get; set; }
            public string IsahUnit { get; set; }
        }

        public string UnitMappingUrl = "http://localhost:6789/api/EngineeringUnitMapping/";

    }
}
