ToolStripManager.Merge Methode

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

Parameters

Retouren

true als de samenvoeging is geslaagd; anders, false.

Opmerkingen

Gebruik de ToolStripManager.Merge methode om objecten van hetzelfde type te combineren ToolStrip , zoals ToolStrip objecten met andere ToolStrip objecten, MenuStrip objecten met andere MenuStrip objecten, enzovoort.

Gebruik de ToolStripManager.Merge methode om objecten van verschillende typen te combineren ToolStrip .

De ToolStrip.AllowMerge eigenschap moet worden ingesteld true op voor beide ToolStrip objecten en de bron- en doeltypen moeten identiek zijn, of deze methode retourneert false.
