ToolBarButton controls are parented by ToolBar controls. Common properties to set once the toolbar button has been created are Text and ImageIndex. Set the Text property of the button to display text beneath or to the right of the image. To assign images to the buttons by creating an ImageList, assigning it to the ImageList property of the toolbar; then assign the image index value to the ImageIndex property of the button.

To change the appearance of the toolbar buttons assigned to the toolbar, set the Appearance property of the parent toolbar control. The ToolBarAppearance.Flat appearance gives the buttons a flat appearance. As the mouse pointer moves over the buttons, their appearance changes to three-dimensional. Button separators appear as lines rather than spaces between the buttons when the buttons have a flat appearance. If the Appearance property is set to ToolBarAppearance.Normal, the buttons appear raised and three-dimensional, and the separators appear as a gap between the buttons.

You can assign a ContextMenu to a button if the Style property is set to ToolBarButtonStyle.DropDown. When the button is clicked, the assigned menu is displayed.

To create a collection of ToolBarButton controls to display on a ToolBar, add the buttons individually by using the Add method of the Buttons property. Alternatively, you can add several toolbar buttons using the AddRange method.

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 all been created.

Public Sub InitializeMyToolBar()
    ' Create and initialize the ToolBar and ToolBarButton controls.
    Dim toolBar1 As New ToolBar()
    Dim toolBarButton1 As New ToolBarButton()
    Dim toolBarButton2 As New ToolBarButton()
    Dim toolBarButton3 As 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.
    ' Add the event-handler delegate.
    AddHandler toolBar1.ButtonClick, AddressOf Me.toolBar1_ButtonClick
    ' Add the ToolBar to the Form.
End Sub    

Private Sub toolBar1_ButtonClick(ByVal sender As Object, _
ByVal e As ToolBarButtonClickEventArgs)

    ' Evaluate the Button property to determine which button was clicked.
    Select Case 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.
    End Select
End Sub
