So I decided to make my contribution to the community. It's time to give something back.
Why do we need yet another wizard control sample, you might ask. My opinion on that is that there's never enough samples on any specific matter.
This control uses VS.NET designers to give you a native support in the IDE. You can add pages to the wizard in the same way you add pages to a tab control. You can place additional controls on the wizard pages.
The control provides run-time events for controlling page navigation. I provided a sample application, with code, to demonstrate this.
The layout of the pages is based on the Wizard 97 Specification from MSDN, particularly on Graphic Design for Wizard Art for welcome and completion pages and interior pages also.
Using the control
Start by creating a new Windows Forms application.
Change the form's name to
SampleWizard. Also make the following settings:
FormBorderStyle = FormBorderStyle.FixedDialog;
MaximizeBox = false;
MinimizeBox = false;
StartPosition = FormStartPosition.CenterScreen;
Text = "Sample Wizard";
Add a reference to the compiled Controls.dll assembly. The control should appear in the toolbox now:
If you double click on the item in the toolbox, an empty wizard will appear on the form:
I set the default docking style of the wizard control to
DockingStyle.Fill because usually there is nothing else on a Wizard dialog than the wizard itself.
Notice that the wizard properties appear in the property grid grouped under the Wizard category.
There are not many properties. This is just a sample control. You can extend it in any way you like, or you may suggest new functionality to me and I just could add those properties in the future.
To add pages to the wizard, you need to click on the Pages properties ellipsis button. The WizardPage Collection Editor appears.
Here I added the first page and set its style properties to
There possible values for the wizard page's
Style properties are:
WizardPageStyle.Standard WizardPageStyle.Welcome WizardPageStyle.Finish WizardPageStyle.Custom
There are also two properties used to specify the title and description of each page. The page draws these texts at the right location depending on the page style. Note that a
Custom page does not draw its texts, you are responsible for drawing them or you may not set them at all.
To set the images that appear on the page you need to go on the wizard itself. Here is an example using the pictures I provided with this sample:
I chose to implement the images properties at the main control level to provide a consistent look to the wizard pages. If you want each page to have its own images you may change this implementation.
The welcome page should look now like this screenshot:
Adding and setting the other pages is pretty straightforward.
You can use the control in the same way you use a
Tab control. You add pages to the
Pages collection and then you place additional controls on the wizard page, just like on a
The coolest thing is that you can switch wizard pages at design time by clicking on the Back and Next buttons.
Using the code
Here are some sample code bits of handling the wizard control's events to provide the user with validation and more interaction:
private void wizardSample_AfterSwitchPages(object sender,
WizardPage newPage = this.wizardSample.Pages[e.NewIndex];
if (newPage == this.pageLicense)
this.wizardSample.NextEnabled = this.checkIAgree.Checked;
else if (newPage == this.pageProgress)
The above code shows you how to provide custom initialization of controls in the page about to be displayed.
private void wizardSample_BeforeSwitchPages(object sender,
WizardPage oldPage = this.wizardSample.Pages[e.OldIndex];
if (oldPage == this.pageOptions && e.NewIndex > e.OldIndex)
if (this.optionCheck.Checked == false &&
this.optionSkip.Checked == false)
MessageBox.Show("Please chose one of the options presented.",
e.Cancel = true;
else if (this.optionSkip.Checked)
The above code shows you how to provide custom validation before leaving a page.
private void wizardSample_Cancel(object sender,
bool isTaskRunning = this.timerTask.Enabled;
this.timerTask.Enabled = false;
if (MessageBox.Show("Are you sure you wand to exit the Sample Wizard?",
MessageBoxIcon.Question) != DialogResult.Yes)
e.Cancel = true;
this.timerTask.Enabled = isTaskRunning;
This code shows you how to display a confirmation message to the user when one cancels the wizard.
private void wizardSample_Finish(object sender, System.EventArgs e)
MessageBox.Show("The Sample Wizard finished succesfuly.",
The above code simply displays a notification message after the wizard finishes.
private void wizardSample_Help(object sender, System.EventArgs e)
MessageBox.Show("This is a realy cool wizard control!\n:-)",
The above code simply displays a notification when the user presses the Help button.
I need to mention that the code is based on Al Gardner's article on wizards: Designer centric Wizard control from which I took the design-time clicking functionality. I simplified the design of the component using less classes. Everything else is pretty much built from scratch.
- September 5th 2005. Minor corrections.
- August 12th 2005. Overrode
BeforeSwitchPagesEventArgs to allow page skipping and provided a new sample page to be skipped.
- July 2nd 2005. Fixed some behaviour and added Help button.
- June 24th 2005. Initial release.
