RevertMerge(String)

復原兩個 ToolStrip 物件的合併，讓具有指定名稱的 ToolStrip 回到在其合併之前的狀態，並取消之前所有的合併作業。

public:
 static bool RevertMerge(System::String ^ targetName);

public static bool RevertMerge (string targetName);

static member RevertMerge : string -> bool

Public Shared Function RevertMerge (targetName As String) As Boolean

參數

targetName: String

要復原合併作業的 ToolStripItem 名稱。

傳回

Boolean

如果合併的復原作業成功，則為 true，否則為 false。

備註

這 ToolStrip.AllowMerge 兩個 ToolStrip 物件都必須將屬性設定 true 為，否則這個方法會傳 false 回。
