Gridview內部的文本框的數值驗證

我在gridview裏面有文本框。需要驗證這個文本框的數值。我嘗試使用下面的代碼，但它的giveng me對象需要error.my代碼如下所示。Gridview內部的文本框的數值驗證

<asp:TabContainer ID="tcexe" runat="server" ActiveTabIndex="0" AutoPostBack="true"> 
<asp:tabpanel> 
<asp:gridview> 
<ItemTemplate> 
<asp:TextBox ID="txt1" runat="server" MaxLength="4" Text='<%# Eval("value") %>' 
    OnKeyPress=" return AllowNumericOnly(this);"> javascirpt used is function 
</ItemTemplate> 
</asp:TenGrid> 
</asp:tabpanel> 

AllowNumericOnly(e) 
{ 
    var keycode; 
    if (window.event) 
      keycode = window.event.keyCode; 
    else if (event) 
      keycode = event.keyCode; 
    else if (e) 
      keycode = e.which; 
    else return true; 
    if ((keycode > 47 && keycode <= 57)) { return true; } 
    else { return false; } return true; 
}

我需要在Mozilla和IE中支持此功能。誰能幫助我

不要惹左右鍵碼，只檢查值。用戶可以輸入小數位嗎？什麼值被拖拽或粘貼？ – RobG 2012-01-31 07:17:08

它不應該允許小數。只有整數。 – Akshata 2012-01-31 07:32:04

然後用'/^\ d * $ /。test（inputValue）'等正則表達式驗證內容，如果用戶輸入的不是數字，就給用戶一個提示。 – RobG 2012-02-01 00:10:57
