I copied exactly your code from above to the Markup and made this method in the Code behind... your code looks fine

Add UpdateMode="Conditional" in the UpdatePanel. 

<asp:UpdatePanel runat="server" ID="UpdInfo" UpdateMode="Conditional">
   <ContentTemplate>
       <asp:TextBox ID="TxtInfo" runat="server />
   </ContentTemplate>
</asp:UpdatePanel>
