ToolStripManager.Merge Méthode

public:
 static bool Merge(System::Windows::Forms::ToolStrip ^ sourceToolStrip, System::String ^ targetName);

public static bool Merge (System.Windows.Forms.ToolStrip sourceToolStrip, string targetName);

static member Merge : System.Windows.Forms.ToolStrip * string -> bool

Public Shared Function Merge (sourceToolStrip As ToolStrip, targetName As String) As Boolean

Paramètres

Retours

Boolean

true si la fusion est réussie ; sinon, false.

Exceptions

Remarques

Utilisez la ToolStripManager.Merge méthode pour combiner ToolStrip des objets de type identique, tels que ToolStrip des objets avec d’autres ToolStrip objets, MenuStrip des objets avec d’autres MenuStrip objets, etc.

Utilisez la ToolStripManager.Merge méthode pour combiner ToolStrip des objets de différents types.

La ToolStrip.AllowMerge propriété doit être définie true pour les deux ToolStrip objets, et les types source et cible doivent être identiques, ou cette méthode retourne false.
