Declaration
public event CustomColumnFilterListEventHandler CustomFiterPopupListPublic Event CustomFiterPopupList As CustomColumnFilterListEventHandlerEvent Data
The CustomFiterPopupList event's handler receives an argument of the CustomColumnFilterListEventArgs type. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Column | Gets or sets a column which owns the processed cell. |
| Node | Gets or sets a node which contains the processed cell. |
| Visible | Gets or sets whether the processed value is displayed within a column's Filter Dropdown. |
Remarks
The CustomFiterPopupList event is raised before a column's Filter Dropdown is populated with unique values. This event is raised for each value displayed within the processed column allowing it to be hidden from the list.
The event parameter's CustomColumnFilterListEventArgs.Node and CustomColumnFilterListEventArgs.Column properties specify the processed node and column, respectively. To obtain the processed value, use the TreeListView.GetNodeValue method. To hide a value from the list, set the CustomColumnFilterListEventArgs.Visible property to false.
