@inject IDbContextFactory<NorthwindContext> NorthwindContextFactory

<DxGrid Data="Products"
        EditMode="GridEditMode.EditRow">
    <Columns>
        <DxGridCommandColumn />
        <DxGridDataColumn FieldName="CategoryId" Caption="Category">
            <EditSettings>
                <DxComboBoxSettings Data="Categories"
                                    ValueFieldName="CategoryId"
                                    TextFieldName="CategoryName"
                                    DisabledFieldName="Discontinued"/>
            </EditSettings>
        </DxGridDataColumn>
        <DxGridDataColumn FieldName="ProductName" />
        <DxGridDataColumn FieldName="UnitPrice" />
        <DxGridDataColumn FieldName="UnitsInStock" />
        <DxGridDataColumn FieldName="QuantityPerUnit" />
    </Columns>
</DxGrid>
@code {
    NorthwindContext Northwind { get; set; }
    List<Product> Products { get; set; }
    List<Category> Categories { get; set; }

    protected override async Task OnInitializedAsync() {
        Northwind = NorthwindContextFactory.CreateDbContext();
        Products = await Northwind.Products.ToListAsync();
        Categories = await Northwind.Categories.ToListAsync();
    }

    public void Dispose() {
        Northwind?.Dispose();
    }
}

To change the field that supplies values at runtime, use the IComboBoxSettings.ValueFieldName property.
