Solution 2

The 'CompareValidator' will solve your issue.
1) add the 'CompareValidator'
2) Set the following properties
2.1) ControlToCompare->textbox1
2.2) ControlToValidate-> textbox2
2.3) ErrorMessage-> Your Message goes here
2.4) Operator-> Less than
2.5) SetFocusonError->true
2.6) type-> String/Integet/Date

Note: this is will work only on 'LostFocus' not while inserting into the textbox(if you want you need to use the javascript).

Solution 3

Try following, perfectly working..

XML

<asp:TextBox ID="TextBox4" runat="server"></asp:TextBox><br />
       <asp:TextBox ID="TextBox5" runat="server"></asp:TextBox><br />
       <asp:CompareValidator ID="CompareValidator1" runat="server" ControlToCompare="TextBox4"
           ControlToValidate="TextBox5" ErrorMessage="value should less than first textbox"
           Operator="LessThanEqual" Type="Integer"></asp:CompareValidator>

Thanks
