Walkthrough: Creating a Professionally Styled ToolStrip Control

Article
11/16/2012

You can give your application’s ToolStrip controls a professional appearance and behavior by writing your own class derived from the ToolStripProfessionalRenderer type.

This walkthrough demonstrates how to use ToolStrip controls to create a composite control that resembles the Navigation Pane provided by Microsoft® Outlook®. The following tasks are illustrated in this walkthrough:

Creating a Windows Control Library project.
Designing the StackView Control.
Implementing a Custom Renderer.

When you are finished, you will have a reusable custom client control with the professional appearance of a Microsoft Office® XP control.

To copy the code in this topic as a single listing, see How to: Create a Professionally Styled ToolStrip Control.

Note

The dialog boxes and menu commands you see might differ from those described in Help depending on your active settings or edition. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see Visual Studio Settings.

Prerequisites

In order to complete this walkthrough, you will need:

Sufficient permissions to be able to create and run Windows Forms application projects on the computer where Visual Studio is installed.

Creating a Windows Control Library Project

The first step is to create the control library project.

To create the control library project

Create a new Windows Control Library project named StackViewLibrary.
In Solution Explorer, delete the project's default control by deleting the source file named "UserControl1.cs" or "UserControl1.vb", depending on your language of choice.

For more information, see How to: Remove, Delete, and Exclude Items.
Add a new UserControl item to the StackViewLibrary project. Give the new source file a base name of StackView.

Designing the StackView Control

The StackView control is a composite control with one child ToolStrip control. For more information about composite controls, see Varieties of Custom Controls.

To design the StackView control

From the Toolbox, drag a ToolStrip control to the design surface.

In the Properties window, set the ToolStrip control's properties according to the following table.

Property	Value
Name	stackStrip
CanOverflow	false
Dock	Bottom
Font	Tahoma, 10pt, style=Bold
GripStyle	Hidden
LayoutStyle	VerticalStackWithOverflow
Padding	0, 7, 0, 0
RenderMode	Professional

In the Windows Forms Designer, click the ToolStrip control's Add button and add a ToolStripButton to the stackStrip control.

In the Properties window, set the ToolStripButton control's properties according to the following table.

Property	Value
Name	mailStackButton
CheckOnClick	true
CheckState	Checked
DisplayStyle	ImageAndText
ImageAlign	MiddleLeft
ImageScaling	None
ImageTransparentColor	238, 238, 238
Margin	0, 0, 0, 0
Padding	3, 3, 3, 3
Text	Mail
TextAlign	MiddleLeft

Repeat step 7 for three more ToolStripButton controls.

Name the controls calendarStackButton, contactsStackButton, and tasksStackButton. Set the value of the Text property to Calendar, Contacts, and Tasks, respectively.

Handling Events

Two events are important to make the StackView control behave correctly. Handle the Load event to position the control correctly. Handle the Click event for each ToolStripButton to give the StackView control state behavior similar to the RadioButton control.

To handle events

In the Windows Forms Designer, select the StackView control.
In the Properties window, click Events.
Double-click the Load event to generate the StackView_Load event handler.

In the StackView_Load event handler, copy and paste the following code.

' This method handles the Load event for the UserControl. 
Private Sub StackView_Load(sender As Object, e As EventArgs) Handles MyBase.Load
   ' Dock bottom. 
   Me.Dock = DockStyle.Bottom

   ' Set AutoSize. 
   Me.AutoSize = True 
 End Sub

// This method handles the Load event for the UserControl. 
private void StackView_Load(object sender, EventArgs e)
{
    // Dock bottom. 
    this.Dock = DockStyle.Bottom;

    // Set AutoSize. 
    this.AutoSize = true;
}

In the Windows Forms Designer, select the mailStackButton control.
In the Properties window, click Events.
Double-click the Click event.

The Windows Forms Designer generates the mailStackButton_Click event handler.
Rename the mailStackButton_Click event handler to stackButton_Click.

For more information, see How to: Rename an Identifier.

Insert the following code into the stackButton_Click event handler.

' This method handles the Click event for all 
' the ToolStripButton controls in the StackView. 
Private Sub stackButton_Click(sender As Object, e As EventArgs) Handles mailStackButton.Click, calendarStackButton.Click, contactsStackButton.Click, tasksStackButton.Click
   ' Define a "one of many" state, similar to 
   ' the logic of a RadioButton control. 
   Dim item As ToolStripItem
   For Each item In   Me.stackStrip.Items
         If item IsNot sender AndAlso TypeOf item Is ToolStripButton Then 
             CType(item, ToolStripButton).Checked = False 
         End If 
   Next item
 End Sub

// This method handles the Click event for all 
// the ToolStripButton controls in the StackView. 
private void stackButton_Click(object sender, EventArgs e)
{
    // Define a "one of many" state, similar to
    // the logic of a RadioButton control. 
    foreach (ToolStripItem item in this.stackStrip.Items)
    {
        if ((item != sender) &&
            (item is ToolStripButton))
        {
            ((ToolStripButton)item).Checked = false;
        }
    }
}

In the Windows Forms Designer, select the calendarStackButton control.
In the Properties window, set the Click event to the stackButton_Click event handler.
Repeat steps 10 and 11 for the contactsStackButton and tasksStackButton controls.

Defining Icons

Each StackView button has an associated icon. For convenience, each icon is represented as a Base64-encoded string, which is deserialized before a Bitmap is created from it. In a production environment, you store bitmap data as a resource, and your icons appear in the Windows Forms Designer. For more information, see How to: Add Background Images to Windows Forms.

To define icons

In the Code Editor, insert the following code into the StackView class definition. This code initializes the bitmaps for the ToolStripButton icons.

Private Shared mailBmp As Bitmap
Private Shared calendarBmp As Bitmap
Private Shared contactsBmp As Bitmap
Private Shared tasksBmp As Bitmap

Implementing a Custom Renderer

You can customize most elements of the StackView control my implementing a class that derives from the ToolStripRenderer class. In this procedure, you will implement a ToolStripProfessionalRenderer class that customizes the grip and draws gradient backgrounds for the ToolStripButton controls.

To implement a custom renderer

Insert the following code into the StackView control definition.

This is the definition for the StackRenderer class, which overrides the RenderGrip, RenderToolStripBorder, and RenderButtonBackground methods to produce a custom appearance.

In the StackView control's constructor, create a new instance of the StackRenderer class and assign this instance to the stackStrip control's Renderer property.

Public Sub New()
   Me.InitializeComponent()

   ' Assign icons to ToolStripButton controls. 
   Me.InitializeImages()

   ' Set up renderers. 
   Me.stackStrip.Renderer = New StackRenderer()
 End Sub

public StackView()
{
    this.InitializeComponent();

    // Assign icons to ToolStripButton controls. 
    this.InitializeImages();

    // Set up renderers. 
    this.stackStrip.Renderer = new StackRenderer();
}

Testing the StackView Control

The StackView control derives from the UserControl class. Therefore, you can test the control with the UserControl Test Container. For more information, see How to: Test the Run-Time Behavior of a UserControl.

To test the StackView control

Press F5 to build the project and start the UserControl Test Container.
Move the pointer over the buttons of the StackView control, and then click a button to see the appearance of its selected state.

Next Steps

In this walkthrough, you have created a reusable custom client control with the professional appearance of an Office XP control. You can use the ToolStrip family of controls for many other purposes:

Create shortcut menus for your controls with ContextMenuStrip. For more information, see ContextMenu Component Overview (Windows Forms).
Create a form with an automatically populated standard menu. For more information, see Walkthrough: Providing Standard Menu Items to a Form.
Create a multiple document interface (MDI) form with docking ToolStrip controls. For more information, see How to: Create an MDI Form with Menu Merging and ToolStrip Controls.
