ASP.NET Wizard Steps: Getting form data to next page? - asp.net

Question

I can't figure out how to pass form data from a Wizard Steps Control to a new page. I posted THIS POST some days ago, but the answer here didn't really help me because i can't even get the value from a TextBox on the new page.
I put tried to put this insted of the hiddenfield but <asp:TextBox ID="amount" runat="server" Text="tester"></asp:TextBox> but the Request.Form["amount"] is still just null.
How do i pass form data from a wizard steps control to a new page? Should this really be that hard?

Answer 1

For information that we collect in a wizard usually translates into a business object, then we just pass that object around in a Session variable. That way we have access to it on any page.

Answer 2

Session variable seems to be easier to work with:
Default.aspx markup:
<asp:Wizard runat="server" ID="wizAwesome" FinishDestinationPageUrl="~/TestPage.aspx" OnFinishButtonClick="wizAwesome_FinishButtonClick">
<WizardSteps>
<asp:WizardStep ID="stepRock" runat="server" Title="Rock!">
This is a wizard step.
<asp:HiddenField runat="server" ID="hiddenName" Value="Juliet" />
</asp:WizardStep>
</WizardSteps>
</asp:Wizard>
Default.aspx.cs
protected void wizAwesome_FinishButtonClick(object sender, WizardNavigationEventArgs e)
{
Session["hiddenName"] = hiddenName.Value;
}
TestPage.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
lblName.Text = Session["hiddenName"].ToString();
}

Your HiddenField needs to be located outside of the Wizard like below and you need to add a FinishNavigationTemplate which posts the data to your new page
<asp:Wizard runat="server" ID="wzd_Amount">
<WizardSteps>
<asp:WizardStep ID="step_Amount" runat="server">
This is a wizard step.
</asp:WizardStep>
</WizardSteps>
<FinishNavigationTemplate>
<asp:Button runat="server" ID="btn_Finish" PostBackUrl="~/Labs/TestPage.aspx" />
</FinishNavigationTemplate>
</asp:Wizard>
<asp:HiddenField runat="server" ID="hdf_Amount" Value="Test" />
On the other page you can just Request the data like so
lbl_Test.Text = Request["hdf_Amount"];
