ASPxPivotGrid.FieldFilterChanging Event

Allows you to customize the filter that is being applied or cancel filtering.

Namespace:DevExpress.Web.ASPxPivotGrid
Assembly:DevExpress.Web.ASPxPivotGrid.v18.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type PivotFieldFilterChangingEventArgs containing data related to this event.

The following PivotFieldFilterChangingEventArgs properties provide information specific to this event.
Property Description
Cancel Gets or sets whether to cancel changing the filter condition.
Field
FilterType Gets the current filter type.
Values Gets the collection of filter values about to be assigned to the filter.

Expanded Remarks

The FieldFilterChanging event occurs before a field's filter condition is changed. To obtain the collection of filter values which is about to be assigned to the filter, use the event parameter's PivotFieldFilterChangingEventArgs.Values property. To cancel changing the current filter values collection, set the PivotFieldFilterChangingEventArgs.Cancel property to true. You can also obtain the field for which the filter condition is being changed, and the current filter type using the event parameter's DevExpress.XtraPivotGrid.PivotFieldEventArgsBase`1.Field and PivotFieldFilterChangingEventArgs.FilterType properties, respectively.

After the filter condition has been changed, the FieldFilterChanged event is fired.

Note

To remove default filter items and add custom items instead, use the CustomFilterPopupItems event.

Expanded Example

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E2846.

The following example shows how to prevent end-users from changing the filter condition.

In this example, the FieldFilterChanging event is handled to prevent an end-user from hiding the 'Beverages' field value. If an end-user tries to hide the 'Beverages' field value, the event handler sets the event parameter's Cancel property to true to cancel changing the filter condition.
