Public ReadOnly Property StartingPoint As Point

Point,表示搜尋的開始位置。

範例

下列程式碼範例示範如何使用這個成員。 在此範例中,事件處理常式會報告事件的發生次數 ListView.SearchForVirtualItem 。 此報告可協助您瞭解事件發生的時間,並可協助您進行偵錯。 若要報告多個事件或經常發生的事件,請考慮將 取代 MessageBox.ShowConsole.WriteLine 或將訊息附加至多行 TextBox

若要執行範例程式碼,請將它貼入包含名為 ListView1 之類型 ListView 實例的專案。 然後,確定事件處理常式與 事件相關聯 ListView.SearchForVirtualItem

private void ListView1_SearchForVirtualItem(Object sender, SearchForVirtualItemEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "IsTextSearch", e.IsTextSearch );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "IncludeSubItemsInSearch", e.IncludeSubItemsInSearch );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Index", e.Index );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "IsPrefixSearch", e.IsPrefixSearch );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Text", e.Text );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "StartingPoint", e.StartingPoint );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Direction", e.Direction );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "StartIndex", e.StartIndex );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "SearchForVirtualItem Event" );
}
Private Sub ListView1_SearchForVirtualItem(sender as Object, e as SearchForVirtualItemEventArgs) _ 
     Handles ListView1.SearchForVirtualItem

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "IsTextSearch", e.IsTextSearch)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "IncludeSubItemsInSearch", e.IncludeSubItemsInSearch)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Index", e.Index)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "IsPrefixSearch", e.IsPrefixSearch)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Text", e.Text)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "StartingPoint", e.StartingPoint)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Direction", e.Direction)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "StartIndex", e.StartIndex)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"SearchForVirtualItem Event")

End Sub

您可以使用 方法來依位置 FindNearestItem 搜尋 ListView 控制項,也可以使用 方法來執行文字搜尋 FindItemWithText
