HOW TO：自訂 ASP.NET CreateUserWizard 控制項

  • 發行項

更新：2007 年 11 月

您可以使用 CreateUserWizardStep 和 CompleteWizardStep 範本，自訂 CreateUserWizard 控制項的內容。透過指定範本的內容，可以指定本身包含控制項的自訂使用者介面 (UI)，CreateUserWizard 控制項會使用這些控制項收集新使用者的資訊，以及指定的其他控制項資訊 (如需 CreateUserWizard 控制項可以使用的控制項清單，請參閱自訂 ASP.NET 登入控制項的外觀)。

此外，由於 CreateUserWizard 控制項是繼承自 Wizard 類別，您可以將自己的自訂步驟加入至 CreateUserWizard 控制項。如需 Wizard 控制項的詳細資訊，請參閱Wizard Web 伺服器控制項概觀。

注意事項：

您也可以使用主題和樣式屬性 (Property)，自訂 CreateUserWizard 控制項的外觀。如需詳細資訊，請參閱 ASP.NET 佈景主題和面板概觀和 CreateUserWizard 控制項的屬性。

若要自訂 CreateUserWizard 步驟

  1. 使用下列語法將 CreateUserWizard 控制項放在網頁上：

    <asp:CreateUserWizard ID="CreateUserWizard1" Runat="server">
  <WizardSteps>
    <asp:CreateUserWizardStep >
    </asp:CreateUserWizardStep>
    <asp:CompleteWizardStep >
    </asp:CompleteWizardStep>
  </WizardSteps>
</asp:CreateUserWizard>

  2. 若要自訂使用者帳戶建立步驟，請在 <asp:CreateUserWizardStep> 項目內建立 <ContentTemplate> 項目。在範本內，新增標記和控制項，以定義收集所需使用者資訊的 UI 配置和內容。

    注意事項：

    如果成員資格提供者使用自訂成員擴充 MembershipProvider 類別，則必須加入所有控制項，以收集成員資格提供者建立新使用者所需的自訂資訊。如需詳細資訊，請參閱 CreateUserWizardStep。

    下列程式碼範例會顯示 CreateUserStep 屬性，其中包括可讓使用者指定其他選項的 CheckBox 控制項。

            </tr>
            <tr>

                </td>
            </tr>
        </table>
        <asp:CheckBox ID="SubscribeCheckBox"  Checked="True" Text="Send me a monthly newsletter." />
        <br />
        <asp:CheckBox ID="ShareInfoCheckBox"  Checked="True" Text="Share my information with partner sites." />
    </ContentTemplate>
</asp:CreateUserWizardStep>

  3. 若要自訂完成步驟，請在 <asp:CompleteWizardStep> 項目中建立 <ContentTemplate> 項目。在範本內，新增標記和控制項，以定義顯示確認訊息和可選擇性地允許使用者巡覽以繼續的 UI 配置和內容(您必須提供控制項才能收集成員資提供者需要的資訊，以建立新的使用者帳戶。如需詳細資訊，請參閱CompleteWizardStep)。

    下列程式碼範例會顯示 CompleteStep 屬性，這個屬性會參考前一個範例的 CheckBox 控制項。

    <asp:CompleteWizardStep ID="CompleteWizardStep1" >
    <ContentTemplate>
        <table border="0" style="font-size: 100%; font-family: Verdana" id="TABLE1" >
            <tr>
                <td align="center" colspan="2" style="font-weight: bold; color: white; background-color: #5d7b9d; height: 18px;">
                    Complete</td>
            </tr>
            <tr>
                <td>
                    Your account has been successfully created.<br />
                    <br />
                    <asp:Label ID="SubscribeLabel"  Text="You have elected to receive our monthly newsletter."></asp:Label><br />
                    <br />
                    <asp:Label ID="ShareInfoLabel"  Text="You have elected to share your information with partner sites."></asp:Label></td>
            </tr>
            <tr>
                <td align="right" colspan="2">
                    &nbsp;<asp:Button ID="ContinueButton"  BackColor="#FFFBFF" BorderColor="#CCCCCC"
                        BorderStyle="Solid" BorderWidth="1px" CausesValidation="False" CommandName="Continue"
                        Font-Names="Verdana" ForeColor="#284775" Text="Continue" ValidationGroup="CreateUserWizard1" />
                </td>
            </tr>
        </table>
    </ContentTemplate>
</asp:CompleteWizardStep>

    <asp:CompleteWizardStep ID="CompleteWizardStep1" >
    <ContentTemplate>
        <table border="0" style="font-size: 100%; font-family: Verdana" id="TABLE1" >
            <tr>
                <td align="center" colspan="2" style="font-weight: bold; color: white; background-color: #5d7b9d; height: 18px;">
                    Complete</td>
            </tr>
            <tr>
                <td>
                    Your account has been successfully created.<br />
                    <br />
                    <asp:Label ID="SubscribeLabel"  Text="You have elected to receive our monthly newsletter."></asp:Label><br />
                    <br />
                    <asp:Label ID="ShareInfoLabel"  Text="You have elected to share your information with partner sites."></asp:Label></td>
            </tr>
            <tr>
                <td align="right" colspan="2">
                    &nbsp;<asp:Button ID="ContinueButton"  BackColor="#FFFBFF" BorderColor="#CCCCCC"
                        BorderStyle="Solid" BorderWidth="1px" CausesValidation="False" CommandName="Continue"
                        Font-Names="Verdana" ForeColor="#284775" Text="Continue" ValidationGroup="CreateUserWizard1" />
                </td>
            </tr>
        </table>
    </ContentTemplate>
</asp:CompleteWizardStep>

  4. 加入程式碼以參考其他控制項。例如，處理 CreatingUser 事件可讓您輸入程式碼，以便於建立新使用者帳戶之前收集、驗證和修改資訊。

    下列程式碼範例會顯示 CreatedUser 事件的處理常式，這個處理常式會參考先前範例的 CheckBox 控制項，並將這些控制項加入至新建立之使用者帳戶的 Comment 屬性。您需要將 OnCreatedUser 屬性 (Attribute) 加入至頁面上的 CreateUserWizard 控制項，這個頁面會參考 CreatedUser 事件的處理常式 (例如，OnCreatedUser="CreateUserWizard1_CreatedUser")。

    Protected Sub CreateUserWizard1_CreatedUser(ByVal sender As Object, ByVal e As EventArgs)
    ' Determine the checkbox values.
    Dim subscribeCheckBox As CheckBox = _
      CType(CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("SubscribeCheckBox"), CheckBox)
    Dim shareInfoCheckBox As CheckBox = _
      CType(CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("ShareInfoCheckBox"), CheckBox)
    Dim userNameTextBox As TextBox = _
      CType(CreateUserWizardStep1.ContentTemplateContainer.FindControl("UserName"), TextBox)


    Dim user As MembershipUser = Membership.GetUser(userNameTextBox.Text)
    User.Comment = "Subscribe=" & subscribeCheckBox.Checked.ToString() & "&" & _
                   "ShareInfo=" & shareInfoCheckBox.Checked.ToString()
    Membership.UpdateUser(user)

    ' Show or hide the labels based on the checkbox values.
    Dim subscribeLabel As Label = _
      CType(CreateUserWizard1.CompleteStep.ContentTemplateContainer.FindControl("SubscribeLabel"), Label)
    Dim shareInfoLabel As Label = _
      CType(CreateUserWizard1.CompleteStep.ContentTemplateContainer.FindControl("ShareInfoLabel"), Label)

    subscribeLabel.Visible = subscribeCheckBox.Checked
    shareInfoLabel.Visible = shareInfoCheckBox.Checked
End Sub

    protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
{
  // Determine the checkbox values.
  CheckBox subscribeCheckBox = 
    (CheckBox)CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("SubscribeCheckBox");
  CheckBox shareInfoCheckBox =
    (CheckBox)CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("ShareInfoCheckBox");
  TextBox userNameTextBox = 
    (TextBox)CreateUserWizardStep1.ContentTemplateContainer.FindControl("UserName");

  MembershipUser user = Membership.GetUser(userNameTextBox.Text);
  user.Comment = "Subscribe=" + subscribeCheckBox.Checked.ToString() + "&" +
                 "ShareInfo=" + shareInfoCheckBox.Checked.ToString();
  Membership.UpdateUser(user);

  // Show or hide the labels based on the checkbox values.
  Label subscribeLabel = 
    (Label)CreateUserWizard1.CompleteStep.ContentTemplateContainer.FindControl("SubscribeLabel");
  Label shareInfoLabel =
    (Label)CreateUserWizard1.CompleteStep.ContentTemplateContainer.FindControl("ShareInfoLabel");

  subscribeLabel.Visible = subscribeCheckBox.Checked;
  shareInfoLabel.Visible = shareInfoCheckBox.Checked;
}

若要加入精靈步驟

  1. 將 <asp:WizardStep> 項目加入至 CreateUserWizard 控制項的 <WizardSteps> 區段。在自訂的 CreateUserWizard 控制項將使用的其他精靈步驟中，加入任何控制項和標記。

    例如，下列程式碼範例會顯示要在 CreateUserWizard 控制項 (包括可讓使用者輸入使用者名稱的文字方塊控制項) 之 CreateUserStep 前加入的步驟。將檢查使用者名稱，以確定該名稱不在成員資格資料庫中。

    <asp:WizardStep ID="CreateUserWizardStep0" >
     <table border="0" style="font-size: 100%; font-family: Verdana" id="TABLE1" >
          <tr>
              <td align="center" colspan="2" style="font-weight: bold; color: white; background-color: #5d7b9d">
                  Select an Account Name</td>
          </tr>
          <tr>
              <td>
                <asp:Label ID="AccountNameLabel"  AssociatedControlID="SearchAccount" > 
                  Account Name:</asp:Label>
                <asp:TextBox ID="SearchAccount" ></asp:TextBox><br />
                <asp:Label ID="SearchAccountMessage"  ForeColor="red" />                                          
              </td>
          </tr>
      </table>

  2. 對精靈步驟加入程式碼。您可以處理 Wizard 控制項的 NextButtonClick 事件，以執行程式碼。CurrentStepIndex 屬性值會指出步驟索引編號 (第一個步驟從 0 開始) 所引發之 NextButtonClick 事件的其他精靈步驟。

    下列程式碼範例會顯示 NextButtonClick 事件的處理常式，這個處理常式會使用在精靈步驟 (來自先前的程式碼範例) 的 TextBox 控制項中輸入的使用者名稱，並驗證使用者名稱不是空白並且目前不在成員資格資料庫中。您需要將 OnNextButtonClick 屬性加入至頁面上的 CreateUserWizard 控制項，這個頁面會參考 NextButtonClick 事件處理常式的處理常式 (例如，OnNextButtonClick="CreateUserWizard1_NextButtonClick")。

    Private Function UserExists(ByVal username As String) As Boolean
    If Membership.GetUser(username) IsNot Nothing Then Return True

    Return False
End Function

Protected Sub CreateUserWizard1_NextButtonClick(ByVal sender As Object, ByVal e As WizardNavigationEventArgs)
    If e.CurrentStepIndex = 0 Then
        If SearchAccount.Text.Trim() = "" OrElse UserExists(SearchAccount.Text) Then
            SearchAccountMessage.Text = "That account already exists. Please select an different account name."
            e.Cancel = True
        Else
            Dim userName As TextBox = _
              CType(CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("UserName"), TextBox)
            userName.Text = SearchAccount.Text
            SearchAccountMessage.Text = ""
            e.Cancel = False
        End If
    End If
End Sub

    private bool UserExists(string username)
{
    if (Membership.GetUser(username) != null) { return true; }

    return false;
}

protected void CreateUserWizard1_NextButtonClick(object sender, WizardNavigationEventArgs e)
{
    if (e.CurrentStepIndex == 0)
    {
        if (SearchAccount.Text.Trim() == "" || UserExists(SearchAccount.Text))
        {
            SearchAccountMessage.Text = "That account already exists. Please select an different account name.";
            e.Cancel = true;
        }
        else
        {
            TextBox userName =
              (TextBox)CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("UserName");
            userName.Text = SearchAccount.Text;
            SearchAccountMessage.Text = "";
            e.Cancel = false;
        }
    }
}
    安全性注意事項：

    這個控制項有一個可接受使用者輸入的文字方塊，這可能會造成安全性威脅。ASP.NET Web 網頁預設會驗證使用者輸入，以確保輸入中未包含 HTML 項目或指令碼。如需詳細資訊，請參閱指令碼攻擊概觀。

範例

下列程式碼範例會顯示使用範本的 CreateUserWizard 控制項，這些範本主要是對兩個基礎步驟所定義：CreateUserStep 和 CompleteStep，並且會在 CreateUserStep 之前加入其他精靈步驟。

安全性注意事項：

此控制項具有接受使用者輸入的文字方塊，而這是一項可能的安全性威脅。在 Web 網頁中的使用者輸入可能會含有惡意的用戶端指令碼。ASP.NET Web 網頁預設會驗證使用者輸入，以確保輸入中未包含 HTML 項目或指令碼。一旦啟用了驗證，就不需要明確檢查使用者輸入中的指令碼或 HTML 項目。如需詳細資訊，請參閱指令碼攻擊概觀。
