ASPxCardViewHeaderFilterEventHandler	An ASPxCardViewHeaderFilterEventHandler delegate method allowing you to implement custom processing.

Remarks

End users can use the header filter to filter column values. To invoke the filter dropdown, end user should click the filter button.

Run Demo: CardView - Header Filter

Note

• You can use custom filter items to filter only the current column values.

• The header filter supports HTML tags in item texts.

• The HeaderFilterFillItems event does not fire if the BeforeHeaderFilterFillItems event’s Handled property is set to false.

C#

@Html.DevExpress().CardView(

        //...
        settings.HeaderFilterFillItems = (sender, e) => {
            if (e.Column.FieldName != "UnitPrice") return;
            e.AddValue(String.Format("from {0} to {1}", 0, 100), string.Empty, String.Format("[UnitPrice] > {0} and [UnitPrice] < {1}", 0, 100));
