valicate textbox to accept only numeric value

<asp:Label ID="lblMinutes" runat="server" Text="Minutes :"></asp:Label>
&nbsp;

<asp:TextBox ID="txtMinutes" runat="server" Height="20px" Width="45px"
                    Style="text-align:center" CssClass="txtstyle"></asp:TextBox>
               

<cc1:NumericUpDownExtender ID="txtMinutes_NumericUpDownExtender" runat="server"
                    Enabled="True" Maximum="59"
                    Minimum="00" RefValues="" ServiceDownMethod=""
                    ServiceDownPath="" ServiceUpMethod="" Tag="" TargetButtonDownID=""
                    TargetButtonUpI

 My code behind is VB.NET. I use ASP.NET UpdatePanel like the following. However, after the post-back, all textbox in UpdatePanel won't accept any input, except when I move the mouse over and click on the TextBox.

• Here's why I use UpdatePanel:
  
  During the post-back, after inserting data into DB, set all TextBox text property to String.Empty
  
  After the form is submitted, the Panel pStudent should be refresh , not the entire page
  
  and the TextBox txtId is set in focus again.

It's very strange that this happened to me today. I used UpdatePanel before many time I never had such problem.

Can anyone show me why  all TextBox controls in UpdatePanel won't accept any input after the post-back even though the textbox is focused , only when you move mouse click in them? 

    <asp:UpdatePanel ID="upPOS" runat="server">
        <ContentTemplate>
            <asp:Panel ID="pStudent" runat="server" CssClass="InContentInfoLight" 
        DefaultButton="btnSubmit" GroupingText="Cafeteria - POS">
                <br />
                <div class ="divleftcolumn-six">
                    ID Number :
                    <asp:TextBox ID

I have several textboxes with an Advanced Data Binding of "Currency" with "Null value = 0.00" and "Decimal Places = 2".  The textboxes perform financial calculations, but when you put a penny amount (regardless of dollar amount), the textbox will lock up and not allow you to exit the program or click on any other textbox.

If I go into the 'Advanced Data Binding' property of any of the textboxes, then I change the 'Data Source Update Mode' to "Never", I can then click out of the textbox. It does not allow me to save, however.

Why is this happening? Is there a better way to have a currency textbox?

Thanks in advance.
