Wizard In C#

As we know there is no wizard class in .net framework. I just write two classes for control wizard in C#.

The code list here.

 

1, BaseWizardForm

public enum WizardButtons { None, OK, Cancel, OKCancel, NextCancel, BackNextCancel, BackFinishCancel, } public partial class BaseWizardForm : Form { /// <summary> /// Required designer variable. /// </summary> private System.ComponentModel.IContainer components = null; /// <summary> /// Clean up any resources being used. /// </summary> /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param> protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } #region Windows Form Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { this.backCommonButton = new System.Windows.Forms.Button(); this.nextCommonButton = new System.Windows.Forms.Button(); this.cancelCommonButton = new System.Windows.Forms.Button(); this.SuspendLayout(); // // backCommonButton // this.backCommonButton.BackColor = System.Drawing.Color.Transparent; this.backCommonButton.DialogResult = System.Windows.Forms.DialogResult.Retry; this.backCommonButton.FlatStyle = System.Windows.Forms.FlatStyle.Flat; this.backCommonButton.Location = new System.Drawing.Point(194, 338); this.backCommonButton.Name = "backCommonButton"; this.backCommonButton.Size = new System.Drawing.Size(80, 26); this.backCommonButton.TabIndex = 3; this.backCommonButton.Text = "Back"; this.backCommonButton.UseVisualStyleBackColor = true; this.backCommonButton.Click += new System.EventHandler(this.backCommonButton_Click); // // nextCommonButton // this.nextCommonButton.BackColor = System.Drawing.Color.Transparent; this.nextCommonButton.DialogResult = System.Windows.Forms.DialogResult.OK; this.nextCommonButton.FlatStyle = System.Windows.Forms.FlatStyle.Flat; this.nextCommonButton.Location = new System.Drawing.Point(284, 338); this.nextCommonButton.Name = "nextCommonButton"; this.nextCommonButton.Size = new System.Drawing.Size(80, 26); this.nextCommonButton.TabIndex = 4; this.nextCommonButton.Text = "Next"; this.nextCommonButton.UseVisualStyleBackColor = true; this.nextCommonButton.Click += new System.EventHandler(this.nextCommonButton_Click); // // cancelCommonButton // this.cancelCommonButton.BackColor = System.Drawing.Color.Transparent; this.cancelCommonButton.DialogResult = System.Windows.Forms.DialogResult.Cancel; this.cancelCommonButton.FlatStyle = System.Windows.Forms.FlatStyle.Flat; this.cancelCommonButton.Location = new System.Drawing.Point(374, 338); this.cancelCommonButton.Name = "cancelCommonButton"; this.cancelCommonButton.Size = new System.Drawing.Size(80, 26); this.cancelCommonButton.TabIndex = 5; this.cancelCommonButton.Text = "Cancel"; this.cancelCommonButton.UseVisualStyleBackColor = true; this.cancelCommonButton.Click += new System.EventHandler(this.cancelCommonButton_Click); // // BaseWizardForm // this.AcceptButton = this.nextCommonButton; this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.None; this.CancelButton = this.cancelCommonButton; this.ClientSize = new System.Drawing.Size(514, 427); this.Controls.Add(this.cancelCommonButton); this.Controls.Add(this.nextCommonButton); this.Controls.Add(this.backCommonButton); this.MaximizeBox = false; this.MinimizeBox = false; this.Name = "BaseWizardForm"; this.ShowIcon = false; this.ShowInTaskbar = false; this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen; this.Text = "BaseWizardForm"; this.ResumeLayout(false); } #endregion protected Button backCommonButton; protected Button nextCommonButton; protected Button cancelCommonButton; //////////////////////////////////////////////////////////////////////////////////////// protected WizardButtons formButtons = WizardButtons.OKCancel; public WizardButtons WizardButton { get { return this.formButtons; } set { this.formButtons = value; this.ChangeFormButtons(value); } } public BaseWizardForm() { InitializeComponent(); } protected override void OnCreateControl() { base.OnCreateControl(); this.AutoScaleMode = AutoScaleMode.None; } private void ChangeFormButtons(WizardButtons buttons) { this.RePositionButtons(); switch (buttons) { case WizardButtons.None: { this.backCommonButton.Visible = false; this.nextCommonButton.Visible = false; this.cancelCommonButton.Visible = false; } break; case WizardButtons.OK: { this.nextCommonButton.Text = "OK"; this.nextCommonButton.Location = this.cancelCommonButton.Location; this.backCommonButton.Visible = false;

this.cancelCommonButton.Visible = true; } break; case WizardButtons.OKCancel: { this.nextCommonButton.Text = "OK"; this.cancelCommonButton.Text = "Cancel"; this.backCommonButton.Visible = false; this.cancelCommonButton.Visible = true; this.nextCommonButton.Visible = true; } break; case WizardButtons.NextCancel: { this.nextCommonButton.Text = "Next"; this.cancelCommonButton.Text = "Cancel"; this.backCommonButton.Visible = false; this.cancelCommonButton.Visible = true; this.nextCommonButton.Visible = true; } break; case WizardButtons.BackNextCancel: { this.backCommonButton.Text = "Back"; this.nextCommonButton.Text = "Next"; this.cancelCommonButton.Text = "Cancel"; this.backCommonButton.Visible = true; this.cancelCommonButton.Visible = true; this.nextCommonButton.Visible = true; } break; case WizardButtons.BackFinishCancel: { this.backCommonButton.Text = "Back"; this.nextCommonButton.Text = "Finish"; this.cancelCommonButton.Text = "Cancel"; this.backCommonButton.Visible = true; this.cancelCommonButton.Visible = true; this.nextCommonButton.Visible = true; } break; } } private void RePositionButtons() { this.cancelCommonButton.Location = new Point(this.ClientRectangle.Width - this.cancelCommonButton.Width - 10, this.ClientRectangle.Height - this.cancelCommonButton.Height - 10); this.nextCommonButton.Location = new Point(this.cancelCommonButton.Left - this.nextCommonButton.Width - 15, this.ClientRectangle.Height - this.nextCommonButton.Height - 10); this.backCommonButton.Location = new Point(this.nextCommonButton.Left - this.backCommonButton.Width - 15, this.ClientRectangle.Height - this.backCommonButton.Height - 10); this.cancelCommonButton.Visible = true; this.backCommonButton.Visible = true; this.nextCommonButton.Visible = true; } protected override void OnSizeChanged(EventArgs e) { base.OnSizeChanged(e); if (this.cancelCommonButton == null) return; this.ChangeFormButtons(this.formButtons); } private void backCommonButton_Click(object sender, EventArgs e) { if (!this.OnBack()) this.DialogResult = DialogResult.None; } private void nextCommonButton_Click(object sender, EventArgs e) { if (this.WizardButton == WizardButtons.BackFinishCancel) { if (!this.OnFinish()) this.DialogResult = DialogResult.None; } else { if (!this.OnNext()) this.DialogResult = DialogResult.None; } } private void cancelCommonButton_Click(object sender, EventArgs e) { if (!this.OnCancel()) this.DialogResult = DialogResult.None; } protected virtual bool OnBack() { return true; } protected virtual bool OnNext() { return true; } protected virtual bool OnFinish() { return true; } protected virtual bool OnCancel() { return true; } }

 

2, WizardController used to contol which wizard form to display

public class WizardController : Component { private List<BaseWizardForm> formList = new List<BaseWizardForm>(); protected int currentStep = 0; private Timer delayShowDialogTimer; protected IWin32Window parentWindow = null; #region Constructor and Destructor public WizardController() : base() { } #endregion #region IDisposable Members protected override void Dispose(bool disposing) { if (disposing) { foreach (BaseWizardForm form in formList) { if (!form.IsDisposed) form.Dispose(); } } base.Dispose(disposing); } #endregion #region Methods public void AddForm(BaseWizardForm form) { this.formList.Add(form); } public void AddForm(Type formType) { Assembly assembly = Assembly.GetCallingAssembly(); if (assembly == null) return; BaseWizardForm form = assembly.CreateInstance(formType.FullName) as BaseWizardForm; this.AddForm(form); } public void RemoveForm(BaseWizardForm form) { this.formList.Remove(form); } public DialogResult ShowDialog(IWin32Window parent) { this.parentWindow = parent; return this.ShowDialog(); } protected virtual DialogResult ShowDialog() { DialogResult ret = this.formList[this.currentStep].ShowDialog(this.parentWindow); if (ret == DialogResult.OK) { if (this.NextStep()) return this.ShowDialog(); } else if (ret == DialogResult.Retry) { if (this.PreStep()) return this.ShowDialog(); } else { return DialogResult.Cancel; } return ret; } protected virtual bool NextStep() { if (this.currentStep == this.formList.Count - 1) return false; this.currentStep++; return true; } protected virtual bool PreStep() { if (this.currentStep == 0) return false; this.currentStep--; return true; } #endregion }

 

3 How to use.

   A, Create new forms derived from BaseWizardForm and set the forms' WizardButton Property.

   B, Create a new class derived from WizardController and add the forms to the controller.

       public TestWizardController()
        {
            this.AddForm(typeof(Form1));
            this.AddForm(typeof(Form2));
        }

   C, Show the wizard

       TestWizardController test = new TestWizardController()

       test.ShowDialog(null);
