I am using Umbraco v. 6.1.6 and webforms. Trying to create a user control with form fields that could be submitted as an email to a recipient or posted to an SQL data base. Here is my .ascx

<script src="/scripts/cookies.js"></script>


<div id=newUserForm">
    <p>Name: <asp:TextBox ID="user" runat="server" OnTextChanged="user_TextChanged"></asp:TextBox></p>
    <p>Year of High School Graduation: <asp:TextBox ID="year" runat="server" OnTextChanged="year_TextChanged"></asp:TextBox></p>
    <asp:Button ID="Submit" runat="server" OnClientClick="Submit" Text="Submit" />
</div>

I don't know how to post the data from the textBoxes when "OnClientClick", there just isn't any documentation out there on the methods needed. I guess I need help with the CodeBehind for the post.

Also, would like to only make the form visible after a cookie check. I've got the Javascript for the cookie check, but not sure how to implement it with the user control.
