#Remarks
End-users can filter column values using the Header Filter. To invoke the header filter, an end-user should click the filter button. The HeaderFilterFillItems event is raised after default filter items are created and before the filter dropdown is shown; and enables you to add custom filter items.
Note
The custom filter items can only be used for filtering data by the current column.
The data column whose filter button has been clicked is returned by the BootstrapCardViewHeaderFilterEventArgs.Column property. The list of filter values can be accessed using the ASPxGridHeaderFilterEventArgs.Values property.
