SearchForVirtualItemEventArgs.IncludeSubItemsInSearch 属性

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

获取一个值，该值指示搜索是否应包括列表项的子项。

public:
 property bool IncludeSubItemsInSearch { bool get(); };

public bool IncludeSubItemsInSearch { get; }

member this.IncludeSubItemsInSearch : bool

Public ReadOnly Property IncludeSubItemsInSearch As Boolean

属性值

Boolean

如果应在搜索中包括子项，则为 true；否则为 false。

示例

下面的代码示例演示了此成员的用法。 在此示例中，事件处理程序报告事件的发生情况 ListView.SearchForVirtualItem 。 此报告可帮助你了解事件发生的时间，并可以帮助你进行调试。 若要报告多个事件或频繁发生的事件，请考虑将 MessageBox.ShowConsole.WriteLine 消息替换为 或将消息追加到多行 TextBox。

若要运行示例代码，请将其粘贴到包含名为 ListView1的类型的ListView实例的项目中。 然后，确保事件处理程序与 ListView.SearchForVirtualItem 事件相关联。

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

注解

子项通常在视图中Details使用ListView。
