public event AutoFilteredColumnEventHandler AutoFilteredColumn
The event handler receives an argument of type AutoFilteredColumnEventArgs containing data related to this event. The following AutoFilteredColumnEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| Col | Gets or sets the filter column. |
| FilterString | Gets the filter string. |
| Spread | Gets or sets the Spread object. |
The client-side AutoFilteringColumn event is fired before the client sends the filtering request to the server . If the filtering request is not canceled, the client will send the filtering request to the server.
The server-side AutoFilteringColumn event is fired before the filtering operation is executed. If the filtering is not canceled on the server, the server-side AutoFilteredColumn event will be fired after the filtering operation has been executed.
The client-side AutoFilteredColumn event will be fired after the client receives the filtering result from the server.
If the sheetview RowFilter property is null, the following events will not be fired:
AutoFilteringColumn event (server-side), AutoFilteredColumn event (server-side), and the AutoFilteredColumn event (client-side).
If the columns are filtered with code, for example (FpSpread1.ActiveSheetView.AutoFilterColumn(1,”apple”)), then the client-side AutoFilteringColumn event will not be fired. The other three events are fired in the following order:
AutoFilteringColumn (server-side)
AutoFilteredColumn (server-side)
AutoFilteredColumn (client-side)
