I have to add Pan Card Number in my Application. so that The format is like Ex:BNOPS0157F first 5 no. should be alphabet then 4 no. should be numeric and the last is alphabet. How Can do that
use RegularExpressionValidator
to achieve try this...
<asp:RegularExpressionValidator Display="Dynamic" ControlToValidate="txtPan"
ID="regConVal" ValidationExpression="^[A-Za-z]{5}[0-9]{4}[A-Za-z]{1}$" runat="server" ErrorMessage="PAN Number Should be this format 'XXXXX0000X'."
ForeColor="#ff0000" ValidationGroup="ConVal"></asp:RegularExpressionValidator>
in javascript
var pan = "ABCDE1234F"; var pan2 = "ASW4578W32" var patt =/^[A-Za-z]{5}[0-9]{4}[A-Za-z]{1}$/; console.log(patt.test(pan)); console.log(patt.test(pan2));
or in c#
using System.Text.RegularExpressions;
string checkPanNo = @"^[A-Za-z]{5}[0-9]{4}[A-Za-z]{1}$";
bool isPANValid = Regex.IsMatch(txtPanNo.Text.ToString().Trim(), checkPanNo);
if (isPANValid == true)
{
//valid pan number
}
else
{
//invalid pan number
}
//Use below jQuery for PAN Validation.
$(".txtPANID").keypress(function (e) {
var textValue = $(this).val().toUpperCase();
var char = String.fromCharCode(e.which)
console.log(textValue + char);
var regexp = /^([A-Z]([A-Z]([A-Z]([A-Z]([A-Z]([0-9]([0-9]([0-9]([0-9]([A-Z])?)?)?)?)?)?)?)?)?)?$/;
if (!regexp.test(textValue + char))
e.preventDefault();
//return false
});
