Property Value

Type	Description
RenderFragment	Visual representation of filter menu values.

Remarks

Filter menu displays all unique column values as a list, except for dates that are displayed as a hierarchy. You can specify the ListView property in the FilterMenuTemplate to display DateTime and DateTime? values as a plain list.

The following example applies the ListView property to the Order Date column:

<DxGrid Data="GridData"
        FilterMenuButtonDisplayMode="GridFilterMenuButtonDisplayMode.Always">
    <Columns>
        <DxGridDataColumn FieldName="OrderDate">
            <FilterMenuTemplate>
                @context.ListView
            </FilterMenuTemplate>
        </DxGridDataColumn>
        <DxGridDataColumn FieldName="ProductName" MinWidth="100" />
        <DxGridDataColumn FieldName="UnitPrice" DisplayFormat="c2" />
        <DxGridDataColumn FieldName="Quantity" />
        <DxGridDataColumn FieldName="Discount" DisplayFormat="p0" />
        <DxGridDataColumn FieldName="Total"
                          UnboundType="GridUnboundColumnType.Decimal"
                          UnboundExpression="[UnitPrice] * [Quantity] * (1 - [Discount])"
                          DisplayFormat="c2" />
    </Columns>
</DxGrid>

@code {
    object GridData { get; set; }
    IReadOnlyList<Category> Categories { get; set; }

    protected override async Task OnInitializedAsync() {
    Categories = (await NwindDataService.GetCategoriesAsync()).ToList();
        var invoices = await NwindDataService.GetInvoicesAsync();
        var products = await NwindDataService.GetProductsAsync();
        GridData = invoices.Join(products, i => i.ProductId, p => p.ProductId, (i, p) => {
            return new {
                ProductName = i.ProductName,
                CategoryId = p.CategoryId,
                OrderDate = i.OrderDate,
                UnitPrice = i.UnitPrice,
                Quantity = i.Quantity,
                Discount = i.Discount,
                ShippedDate = i.ShippedDate
            };
        });
    }
