You can use a RegularExpressionValidator.

It won't actually stop the user from entering something other than numbers, but it will validate it for you on the client and server side.

<asp:RegularExpressionValidator id="RegularExpressionValidator1" 
                 ControlToValidate="MyTextBox"
                 ValidationExpression="\d+"
                 ErrorMessage="Please enter a number"
                 runat="server"/>

why can you not use any plugin? If you read the post though there is a link to how you can build the code yourself. – Tim B James Mar 23 '11 at 16:05

Regardless of your client-side behavior, you'll probably want a RegularExpressionValidator to verify the requirement on the server.

<asp:RegularExpressionValidator runat="server" 
                                ValidationExpression="\d+"                                    
                                ControlToValidate="NumberTextBox" 
                                ErrorMessage="Only numbers, please"
                                Text="*"
                                Display="Dynamic"
                                SetFocusOnError="true" />

If you have a jQuery plugin to more proactively restrict the input, you may also want to set EnableClientScript to false
