In the aspx page, put:

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="#">HyperLink</asp:HyperLink>
<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True"></asp:TextBox>

In the aspx.vb code-behind, do:

Protected Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
    HyperLink1.NavigateUrl = "mailto:" & TextBox1.Text
End Sub
