How Can I Efficiently Create Multiple Wizards in C# Windows Forms?

Create multiple wizards in C# Windows Forms

For those new to C# Windows Forms wizard creation, it is completely understandable to seek guidance. Here are some insights to get you started:

There are several ways to create multiple wizards. While it is possible to create a separate form for each wizard step, this can cause visual and functional problems. Alternatively, each step can be designed as a user control that can be dynamically switched among the form's control collection. However, this approach increases the complexity of user control design by requiring public properties for each UI element.

A more user-friendly and simplified method is to use a TabControl. It provides a convenient interface in the designer to switch tabs and place controls on each tab. Changing wizard steps is a breeze by adjusting the TabControl's SelectedIndex property.

The only small snag with using the TabControl approach is hiding the tab at runtime. This is achieved by handling specific Windows messages. Here is sample code that handles the message and subsequently hides the tab:

<code class="language-csharp">using System;
using System.Windows.Forms;

class WizardPages : TabControl {
  protected override void WndProc(ref Message m) {
    // 通过捕获TCM_ADJUSTRECT消息来隐藏选项卡
    if (m.Msg == 0x1328 && !DesignMode) m.Result = (IntPtr)1;
    else base.WndProc(ref m);
  }
}</code>

You can create a new class in the form and paste the code, then compile it. After that, drag and drop the new control from the top of the toolbox onto your form. This will enable you to hide the tab while the wizard is running.
