Occurs when a ToolBarButton on the ToolBar is clicked.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

event ToolBarButtonClickEventHandler^ ButtonClick {
	void add(ToolBarButtonClickEventHandler^ value);
	void remove(ToolBarButtonClickEventHandler^ value);

The following code example creates a ToolBar and three ToolBarButton controls. The toolbar buttons are assigned to the button collection, the collection is assigned to the toolbar, and the toolbar is added to the form. On the ButtonClick event of the toolbar, the Button property of the ToolBarButtonClickEventArgs is evaluated, and the appropriate dialog box opened. This code requires that a Form, an OpenFileDialog, a SaveFileDialog, and a PrintDialog have been created.

   void InitializeMyToolBar()
      // Create and initialize the ToolBar and ToolBarButton controls.
      toolBar1 = gcnew ToolBar;
      ToolBarButton^ toolBarButton1 = gcnew ToolBarButton;
      ToolBarButton^ toolBarButton2 = gcnew ToolBarButton;
      ToolBarButton^ toolBarButton3 = gcnew ToolBarButton;

      // Set the Text properties of the ToolBarButton controls.
      toolBarButton1->Text = "Open";
      toolBarButton2->Text = "Save";
      toolBarButton3->Text = "Print";

      // Add the ToolBarButton controls to the ToolBar.
      toolBar1->Buttons->Add( toolBarButton1 );
      toolBar1->Buttons->Add( toolBarButton2 );
      toolBar1->Buttons->Add( toolBarButton3 );

      // Add the event-handler delegate.
      toolBar1->ButtonClick += gcnew ToolBarButtonClickEventHandler(
         this, &Form1::toolBar1_ButtonClick );

      // Add the ToolBar to the Form.
      Controls->Add( toolBar1 );

   void toolBar1_ButtonClick(
      Object^ sender,
      ToolBarButtonClickEventArgs^ e )
      // Evaluate the Button property to determine which button was clicked.
      switch ( toolBar1->Buttons->IndexOf( e->Button ) )
         case 0:
            // Insert code to open the file.
         case 1:
            // Insert code to save the file.
         case 2:
            // Insert code to print the file.
