System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

The event occurs whenever the user clicks on a button on a ToolBar control. The Button property contains the ToolBarButton wiith the information about the button that was clicked.

The following example instantiates 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 opened. This code assumes that a Form, an OpenFileDialog, a SaveFileDialog, and a PrintDialog have been instantiated.

public void InitializeMyToolBar()
 {
    // Create and initialize the ToolBar and ToolBarButton controls.
    toolBar1 = new ToolBar();
    ToolBarButton toolBarButton1 = new ToolBarButton();
    ToolBarButton toolBarButton2 = new ToolBarButton();
    ToolBarButton toolBarButton3 = new 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 += new ToolBarButtonClickEventHandler (
       this.toolBar1_ButtonClick);

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

 private 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:
         openFileDialog1.ShowDialog();
         // Insert code to open the file.
         break; 
      case 1:
         saveFileDialog1.ShowDialog();
         // Insert code to save the file.
         break; 
      case 2:
         printDialog1.ShowDialog();
         // Insert code to print the file.    
         break; 
    }
 }
