Public Event FilterGroupSortChanging As FilterGroupSortChangingEventHandler
The FilterGroupSortChanging event's data class is FilterGroupSortChangingEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| ComplexFilterCriteria | Gets the complex filter that is applied to several columns. |
| GroupCount | Gets or sets the number of group sortings. |
| Handled | Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs. |
| OriginalSource | Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs. |
| RoutedEvent | Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs. |
| SearchString | Gets or sets the search panel’s string. |
| SortInfo | Gets information about the GridControl’s sorting. |
| Source | Gets the GridControl. |
| SplitColumnFilters | Gets filters applied to columns. |
The event data class exposes the following methods:
| Method | Description |
|---|---|
| InvokeEventHandler(Delegate, Object) | When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs. |
| IsFilteredBy(String) | Gets whether the GridControl is filtered by the field name. |
| IsGroupedBy(String) | Gets whether the GridControl is grouped by the field name. |
| IsSortedBy(String) | Gets whether the GridControl is sorted by the field name. |
| OnSetSource(Object) | When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs. |
The FilterGroupSortChanging event allows you to modify applied sort, group, filter, and search options. To do this, use event arguments only (do not modify GridControl properties).
