Blazor Grid Command Column

The following example hides New and Delete command buttons:

@using Microsoft.EntityFrameworkCore
@inject IDbContextFactory<NorthwindContext> NorthwindContextFactory
@implements IDisposable

<DxGrid Data="GridDataSource"
        DataItemDeleting="OnDataItemDeleting"
        KeyFieldName="EmployeeId"
        ShowFilterRow="true">
    <Columns>
        <DxGridCommandColumn NewButtonVisible="false" DeleteButtonVisible="false" />
        <DxGridDataColumn FieldName="FirstName" />
        <DxGridDataColumn FieldName="LastName" />
        <DxGridDataColumn FieldName="Title" />
        <DxGridDataColumn FieldName="HireDate" />
    </Columns>
</DxGrid>

@code {
    IEnumerable<object> GridDataSource { get; set; }
    NorthwindContext Northwind { get; set; }

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

    async Task OnDataItemDeleting(GridDataItemDeletingEventArgs e) {
        var dataItem = Northwind.Employees.Find((e.DataItem as Employee).EmployeeId);
        if (dataItem != null) {
            Northwind.Remove(dataItem);
            await Northwind.SaveChangesAsync();
            GridDataSource = await Northwind.Employees.ToListAsync();
        }
    }

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