ToolBar.ButtonClick Event

Occurs when a ToolBarButton on the ToolBar is clicked.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public event ToolBarButtonClickEventHandler ButtonClick
/** @event */
public void add_ButtonClick (ToolBarButtonClickEventHandler value)

/** @event */
public void remove_ButtonClick (ToolBarButtonClickEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

For more information about handling events, see Consuming Events.

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.

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; 
    }
 }


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.set_Text("Open");
    toolBarButton2.set_Text("Save");
    toolBarButton3.set_Text("Print");

    // Add the ToolBarButton controls to the ToolBar.
    toolBar1.get_Buttons().Add(toolBarButton1);
    toolBar1.get_Buttons().Add(toolBarButton2);
    toolBar1.get_Buttons().Add(toolBarButton3);

    // Add the event-handler delegate.
    toolBar1.add_ButtonClick(new ToolBarButtonClickEventHandler(
                                 this.toolBar1_ButtonClick));

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

protected void toolBar1_ButtonClick(Object sender,
                                    ToolBarButtonClickEventArgs e)
{
    // Evaluate the Button property to determine which button was clicked.
    switch (toolBar1.get_Buttons().IndexOf(e.get_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;
    } 
} //toolBar1_ButtonClick
