                                    TextFieldName="CategoryName"
                                    ShowDropDownButton=false>
                </DxComboBoxSettings>
            </EditSettings>
        </DxGridDataColumn>
        <DxGridDataColumn FieldName="ProductName" Width="25%" />
        <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 show or hide the editor’s drop-down button at runtime, use the IDropDownEditSettings.ShowDropDownButton property.
