Let’s say you have an Add Customer function that gathers information about a new customer using two pages:

• Add Customer page, for collecting and updating basic customer information.
• Add Credit Card information page, for collecting and updating the customer’s credit card information.

The following example demonstrates this Iron Speed Designer feature by splitting an ‘Add Customer’ procedure into a two-step process: first, we gather the customer ID, company name, contact name and contact title. Second, we add customer contact information such as address, phone, FAX, etc. The example is built using the Customers table in the Northwind database.

Step 2: Delete the Save and Cancel buttons since we won’t need to save any data to the database in the first step of our wizard.

Step 3: Click "Configure..." in the Record panel to display the Record Panel Wizard. In the Fields tab, remove all of the fields except CustomerID, CompanyName, ConctactName, and ContactTitle. Then click "Finish".

Step 4: Drag and drop a button from the tool box within the Add Record panel. Set the button text to "Next".

Step 5: Double click the "Next" button to display the Properties dialog box for the button. On the Bindings tab, set these properties:

Property	Setting
Button Command	Redirect
Action after command	Go to a specific URL Specify the path of the second page as the URL.

On the Attributes tab, set these properties:

Property	Setting
Button-CausesValidation	True This ensures the data on the first page will be validated before the second page is displayed.

Step 6: Override the Button_Click() method in the AddCustomerPage class in the first page, located in:

.NET Framework 1.1 and 2.0:

...\<App Folder>\Customers\AddCustomersPage.aspx.cs or .vb

Handle the command for the button as shown below. In this function, the data values are stored in session variables.

C#:

public void Button_Click(object sender, EventArgs args) {     //store data in session variables     System.Web.HttpContext.Current.Session["Customer"] = this.CustomerID.Text;     System.Web.HttpContext.Current.Session["CompanyName"] = this.CompanyName.Text;     System.Web.HttpContext.Current.Session["ContactName"] = this.ContactName.Text;     System.Web.HttpContext.Current.Session["ContactTitle"] = this.ContactTitle.Text;       Button_Click_Base(sender, args); }

Visual Basic .NET:

Public Sub Button_Click(ByVal sender As Object, ByVal args As EventArgs)     System.Web.HttpContext.Current.Session("Customer") = Me.CustomerID.Text     System.Web.HttpContext.Current.Session("CompanyName") = Me.CompanyName.Text     System.Web.HttpContext.Current.Session("ContactName") = Me.ContactName.Text     System.Web.HttpContext.Current.Session("ContactTitle") = Me.ContactTitle.Text     Button_Click_Base(sender, args) End Sub

Step 1: Create an Add Record page using the New Page dialog or Application Wizard in Iron Speed Designer. For this example, use the Customers table in the Northwind database and will call this page AddCustomersPage2.aspx.

Step 2: Click “Configure...” in the Record panel to display the Record Panel Wizard. In the Fields tab, remove the CustomerID, CompanyName, ConctactName, and ContactTitle fields. Then click "Finish".

Step 3: Override the GetUIData() method in the CustomerRecordControl class, located in:

.NET Framework 1.1:

...\<App Folder>\Customers\AddCustomersPage2.Controls.cs or .vb

.NET Framework 2.0:

...\<App Folder>\App_Code\Customers\AddCustomersPage2.Controls.cs or .vb

In this method we collect data from the second wizard page and add the data values from first page that were saved in session variables.

C#:

public override void GetUIData() {     this.DataSource.CustomerID =         System.Web.HttpContext.Current.Session["Customer"].ToString();     this.DataSource.CompanyName =         System.Web.HttpContext.Current.Session["CompanyName"].ToString();     this.DataSource.ContactName =         System.Web.HttpContext.Current.Session["ContactName"].ToString();     this.DataSource.ContactName =         System.Web.HttpContext.Current.Session["ContactTitle"].ToString();   base.GetUIData(); }

Visual Basic .NET:

Public Overrides Sub GetUIData()     Me.DataSource.CustomerID =         System.Web.HttpContext.Current.Session("Customer").ToString()     Me.DataSource.CompanyName =         System.Web.HttpContext.Current.Session("CompanyName").ToString()     Me.DataSource.CompanyName =         System.Web.HttpContext.Current.Session("ContactName").ToString()     Me.DataSource.CompanyName =         System.Web.HttpContext.Current.Session("ContactTitle").ToString()       MyBase.GetUIData() End Sub

By default, the Save button in the last wizard page will point to the previous page. In this case, you might want to modify the properties of the Save button to point to a Show Table page instead.

Step 4: Finally, build and run the application.
