Take a look at the final HTML of your form page in the browser. It contains a <form /> from the ASP.NET page and a nested <form /> from your contact form. Nesting forms is not allowed so when you submit the contact form you actually submit your outer form.

That did it. I deleted the default text inbetween the <body></body> tags.

Try looking into Cross Page PostBacks. You can set the PostBack URL of a *server side* button to the URL of the page you want to submit to. All other controls in your server side form could be simple HTML controls to avoid having their names and IDs changed.

That helps. I see it uses JavaScript. I have the name and submit button as server controls, as you can see in the email response I got back.

ctl00$ContentPlaceHolder1$Button1: Submit
ctl00$ContentPlaceHolder1$PersonName: Barrack Obama

GoDaddy servers are in Phoenix Arizona and they aren't on daylight time, hence their time in the summer is California time.

This is a good link in how to send info to the desination page.

But I am having problems with the SourcePage and DesinationPage.

Right now I am using two server controls and I'm returned a Thank you I will get back to you.

I would like it to say Thank you, [Name] I will get back to you. This will personalize it a bit, and I know clients that if I write them some aspx pages would love this.

It is pretty slick inserting the controls into the markup code as well as the design page. I also fixed up my fancy form a bit, though I am going to work more on it. My tab index was off, so anyone that looked at my copy before, just remember to add after the ID the tabindex from 1, 2, 3, ... otherwise you aggrevate the user.;-)

Santaclaus - I have the Visual C# 2008 Step by Step by John Sharp. If I get a 2010 book I think Imar mentioned one by Wrox.

I am sorry, but there is so much text in this post that I am not sure what you're asking. Can you be more concrete?

Currently when a user clicks the form it goes to: Thank you I will get back to you.

I would like it to say: Thank you, [Name] I will get back to you.

This is the link again that I based my coding on. http://www.aspdotnetfaq.com/Faq/How-...n-ASP-Net.aspx

SourcePage.aspx:

Code:

<form id="form1" runat="server">

        <div>

            First Name:&nbsp;<asp:TextBox ID="FirstName" runat="server"></asp:TextBox><br />

            Last Name:&nbsp;<asp:TextBox ID="LastName" runat="server"></asp:TextBox><br /><br />

            <asp:Button ID="Button1" runat="server" Text="Submit To Destination Page" PostBackUrl="~/CrossPagePostbacks/DestinationPage.aspx" />

        </div>

    </form>

Quote:

When our user clicks the Submit button, all the values from the HTML Form on SourcePage.aspx will be transfered to the DestinationPage.aspx and we will also be able to get reference to the SourcePage.aspx in our DestinationPage with the PreviousPage property like this:

So in our DestinationPage.aspx.cs code-behind we can easily access two TextBox controls on SourcePage.aspx and show them in two label controls like this:

DestinationPage.aspx:

Code:

protected void Page_Load(object sender, EventArgs e)

    {

        // first check if we had a cross page postback

        if ( (PreviousPage != null) && (PreviousPage.IsCrossPagePostBack) )

        {

            Page previousPage = PreviousPage;

            TextBox firstName = (TextBox)previousPage.FindControl("FirstName");

            TextBox lastName = (TextBox)previousPage.FindControl("LastName");

            // we can now use the values from TextBoxes and display them in two Label controls..

            labelFirstName.Text = firstName.Text;

            labelLastName.Text = lastName.Text;

         }

    }

Hope this helps.;-)

But are you still using the classic ASP script to send out the e-mail? If so, CrossPage PostBacks won''t work. You can submit to the ASP page, but you won't hit DestinationPage.aspx as a cross page post back page.

Check out Chapter 9. There are way easier alternatives to do what you need to do. You can find code to send mail starting on page 317, but also spend some time reading the the chapter up to that part.

Cheers,

okay thanks. I will leave it as is until I get to that part. ;-)
