Hi divyasrinivasan,
This is for validating textbox for numeric only :
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="OperationSheetMultipleArticle.aspx.vb" Inherits="OperationSheetMultipleArticle" EnableSessionState="true" %>
<%@ OutputCache Location="Client" duration="5" varybyparam="none" %>
<html xmlns="http://www.w3.org/1999/xhtml" >
<script type="text/javascript" language=javascript>
function keyDownNumber()
{
var key;
if(navigator.appName == 'Microsoft Internet Explorer')
key = event.keyCode;
else
key = event.which
if ( !(key >= 48 && key <= 57) && key != 8 && key != 46 && key != 36 && key != 37)
{
event.returnValue = false;
}
}
</script>

Hi there... still new so please forgive me if I make a mistake... to add validation to a textbox that is inside a gridview...
1. Convert the field into a text field...
2. then add validation into the <EditItemTemplate></EditItemTemplate> and the <InsertItemTemplate></InsertItemTemplate>
as below... :
<asp:TemplateField HeaderText="Client Number" SortExpression="ClientNumber">
<EditItemTemplate>
<asp:TextBox ID="txtClientNumber" runat="server" Text='<%# Bind("ClientNumber") %>'></asp:TextBox>
</EditItemTemplate>
<InsertItemTemplate>
<asp:TextBox ID="txtClientNumber" runat="server" Text='<%# Bind("ClientNumber") %>'></asp:TextBox>
<asp:RequiredFieldValidator ID="val1" runat="server" ControlToValidate="txtClientNumber" ErrorMessage="Client Number Required" Display="Dynamic"></asp:RequiredFieldValidator>
</InsertItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("ClientNumber") %>'></asp:Label>
</ItemTemplate>
<ControlStyle CssClass="editControlTextFields" Width="96%" />
<HeaderStyle Width="110px" />
</asp:TemplateField>how to check the text boxes while editing is the textbox is null or not
you can also use in built validation controls provided by .net framework instead of java script.
