Merge(ToolStrip, String)
- Source:
- ToolStripManager.cs
- Source:
- ToolStripManager.cs
- Source:
- ToolStripManager.cs
Combines two ToolStrip objects of the same type.
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 -> boolPublic Shared Function Merge (sourceToolStrip As ToolStrip, targetName As String) As BooleanParameters
- sourceToolStrip
- ToolStrip
The ToolStrip to be combined with the ToolStrip referred to by the targetName parameter.
- targetName
- String
The name of the ToolStrip that receives the ToolStrip referred to by the sourceToolStrip parameter.
Returns
true if the merge is successful; otherwise, false.
Exceptions
sourceToolStrip or targetName is null.
sourceToolStrip or targetName refer to the same ToolStrip.
Remarks
Use the ToolStripManager.Merge method to combine ToolStrip objects of identical type, such as ToolStrip objects with other ToolStrip objects, MenuStrip objects with other MenuStrip objects, and so on.
Use the ToolStripManager.Merge method to combine ToolStrip objects of different types.
The ToolStrip.AllowMerge property must be set to true for both ToolStrip objects, and the source and target types must be identical, or this method returns false.
Note
If there are two MenuStrip controls on an MDI child form, setting IsMdiContainer to true for the parent form merges the contents of only one of the MenuStrip controls. Use Merge to merge the contents of additional child MenuStrip controls on the MDI parent form.

Remarks
Use the ToolStripManager.Merge method to combine ToolStrip objects of different types.
Use the ToolStripManager.Merge method to combine ToolStrip objects of identical type, such as ToolStrip objects with other ToolStrip objects, MenuStrip objects with other MenuStrip objects, and so on.
The ToolStrip.AllowMerge property must be set to true for both ToolStrip objects, or this method returns false.
Note
If there are two MenuStrip controls on an MDI child form, setting IsMdiContainer to true for the parent form merges the contents of only one of the MenuStrip controls. Use Merge to merge the contents of additional child MenuStrip controls on the MDI parent form.
