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;
        key = event.which
    if ( !(key >= 48 && key <= 57) && key != 8 && key != 46 && key != 36 && key != 37)
        event.returnValue = false;

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">
                <asp:TextBox ID="txtClientNumber" runat="server" Text='<%# Bind("ClientNumber") %>'></asp:TextBox>
                <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>                    
                <asp:Label ID="Label1" runat="server" Text='<%# Bind("ClientNumber") %>'></asp:Label>
            <ControlStyle CssClass="editControlTextFields" Width="96%" />
            <HeaderStyle Width="110px" />

Edited by Ezzaral: Added code tags. Please use them to format any code that you post.


you can also use in built validation controls provided by .net framework instead of java script.


USE thid.id as argument in Validate function.
like I have my javascript function validateData(source) and I called it as follows on update link OnClientClick="return validateData(this.id);"
