Input Field Validation Controls <asp:RegularExpressionValidator ID="loginRegExValidator" runat="server" ControlToValidate="txtUserName" ErrorMessage="Please, enter a valid address." /> Submission Button

protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { Page.Form.DefaultFocus = txtName.ClientID; Page.Form.DefaultButton = cmdShipFormSubmit.UniqueID; // Populate fields with existing shipping info if (Session["ShippingData"] != null) { ShippingData shipping = (ShippingData)Session["ShippingData"]; txtName.Text = shipping.FullName; txtStreet1.Text = shipping.Street1; txtStreet2.Text = shipping.Street2; txtCity.Text = shipping.City; ddState.SelectedValue = shipping.State; txtZip.Text = shipping.Zip; }}}
