備註

Examples

下列程式碼範例會顯示從實作IFilterProvider介面的Microsoft.SharePoint.WebPartPages.WebPart類別的型別ClearFilterEventHandler的事件的宣告。顯示的事件處理常式實作的程式碼範例是主題中的ClearFilter事件。顯示IFilterProvider介面的完整實作的程式碼範例是IFilterProvider主題中。

' Step #3: Declare the IFilterProvider events.
' Because this class implements the IFilterProvider interface, it must 
' declare the interface members SetFilter, ClearFilter, NoFilter. 

Public Event SetFilter As SetFilterEventHandler Implements IFilterProvider.SetFilter
Public Event ClearFilter As ClearFilterEventHandler Implements IFilterProvider.ClearFilter
Public Event NoFilter As NoFilterEventHandler Implements IFilterProvider.NoFilter

// Step #3: Declare the IFilterProvider events.
// Because this class implements the IFilterProvider interface, it must 
// declare the interface members SetFilter, ClearFilter, NoFilter. 

public event SetFilterEventHandler SetFilter;
public event ClearFilterEventHandler ClearFilter;
public event NoFilterEventHandler NoFilter;
