erum,

You can use a FilteredTextBoxExtender for this.

It is part of the AJAX toolkit that is used in asp.net. You should be able to add AjaxControlToolkit to your project references.

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

<cc1:FilteredTextBoxExtender ID="FilteredTextBoxExtender3" TargetControlID="Number_TextBox" FilterMode="ValidChars" ValidChars="0123456789" runat="server" />

This will force the textbox to only accept numbers. Hope that helps. If you have any questions, check out http://www.asp.net/ajax
