Hi experts,

on my webpage i have Textboxes to enter the information.

I have a Textbox with MobileNo as TxtMobileNo, In this the user will enter mobileno. it has set Maximum length to 10.

if the user enters 10 numbers and press on any key the cursor must go the other textbox.

thats it.

help me thanks.

you have to handle keypress event of the textbox.

$('#txtPhoneNumber').keyPress(function() {
    if($(this).val().length == 10) {
Create one javascript method.
in that method check the length of the textbox's text. if it is 10 then set focus to another control.

and call this method on onkeypress event of the textbox.

I have submitted my code as a solution number 5.
Dont forget to mark it as answer and rate this solution.

please add javascript function in textbox key pressed event and maintain
textbox focus base on maxlength


<asp:TextBox ID="txt1" MaxLength="4" runat="server" onkeypress="myFunction(event)"  ></asp:TextBox>
       <asp:TextBox ID="txt2" MaxLength="4" runat="server"></asp:TextBox>
       <script type="text/javascript" >
           function myFunction(event) {
               var str = document.getElementById('<%=txt1.ClientID%>').value;
               if (event.keyCode == 8) {
               else if (str.length == 4) {
               else { }

here we have used keycode 8 for backspace
check it
ASPX Code for TextBox :

<asp:TextBox runat="server" ID="textMobileNo" MaxLength="10" onkeypress="ManageFocus(event)"></asp:TextBox>
<asp:TextBox runat="server" ID="textNew"></asp:TextBox>

Javascript Method:

function ManageFocus(e) {
           var textLength = document.getElementById('<%=textMobileNo.ClientID%>').value.length;
           var maxLength = document.getElementById('<%=textMobileNo.ClientID%>').maxLength;

           if (textLength == maxLength) {

Your answers are quite good, but might I suggest that it would be much easier to follow your train of thought if you were to use the "Improve Solution" widget to update your existing answer with updated information instead of posting a new solution each time. Cheers.
