Blazor Grid Command Column

The following example hides the Clear command button:

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

<DxGrid Data="GridDataSource"
        EditModelSaving="OnEditModelSaving"
        DataItemDeleting="OnDataItemDeleting"
        KeyFieldName="EmployeeId"
        ShowFilterRow="true"
        EditMode="GridEditMode.EditRow">
    <Columns>
        <DxGridCommandColumn ClearFilterButtonVisible="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 OnEditModelSaving(GridEditModelSavingEventArgs e) {
        var editModel = (Employee)e.EditModel;
        // Assign changes from the edit model to the data item.
        if (e.IsNew)
            await Northwind.AddAsync(editModel);
        else
            e.CopyChangesToDataItem();
        // Post changes to the database.
        await Northwind.SaveChangesAsync();
        // Reload the entire Grid.
        GridDataSource = await Northwind.Employees.ToListAsync();
    }

    async Task OnDataItemDeleting(GridDataItemDeletingEventArgs e) {
         // Remove the data item from the database.
        Northwind.Remove(e.DataItem);
        await Northwind.SaveChangesAsync();
        // Reload the entire Grid.
        GridDataSource = await Northwind.Employees.ToListAsync();
    }

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