The CustomFilterDisplayText event's data class is CustomFilterDisplayTextEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| 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. |
| Source | Gets the View that raised the event. |
| Value | Gets or sets the filter expression displayed within the Filter Panel. |
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. |
| 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 DataViewBase.FilterPanelText property returns the filter expression displayed in the legacy Filter Panel. To replace the filter expression displayed within the legacy Filter Panel with the custom text:
<dxg:GridControl FilterString="[OrderDate] > #2020-01-01# And [Freight] > 100.0m" ...>
<dxg:GridControl.View>
<dxg:TableView x:Name="view"
UseLegacyFilterPanel="True"
CustomFilterDisplayText="view_CustomFilterDisplayText">
</dxg:TableView>
</dxg:GridControl.View>
</dxg:GridControl>
void view_CustomFilterDisplayText(object sender, DevExpress.Xpf.Grid.CustomFilterDisplayTextEventArgs e) {
e.Value = "Custom text in the Filter Panel";
}
Private Sub view_CustomFilterDisplayText(ByVal sender As Object, ByVal e As DevExpress.Xpf.Grid.CustomFilterDisplayTextEventArgs)
e.Value = "Custom text in the Filter Panel"
End Sub
