Automatically advance tab position

Below function is to automatically advance tab position from current text control to another text control as soon as soon as current textbox gets filled.

In below function

fromId : id of current text box
fromLen : length of current textBox
toId : id of target textBox

function autoAdvance(fromId, fromLen, toId, evt)
{
var textBox = document.getElementById(fromId);
var charCode = (evt.which) ? evt.which : event.keyCode;
len = textBox.value.length;
if (len == fromLen && ((charCode >= 48 && charCode <= 57) || (charCode >= 96 && charCode <= 105)))
{
document.getElementById(toId).focus();
}
}

Call this function on onKeyUp event of text box.

To open pop-up

To close child window(pop-up) and then refresh the parent window.

Javascript code for closing child and refreshing parent

window.close();
if (window.opener && !window.opener.closed) {
window.opener.location.reload();
}

For using in ASP.NET, write below on event handler of control that initiates close of popup.

ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "CloseWindow", "window.close(); if (window.opener && !window.opener.closed) { window.opener.location.reload(); }", true);

This worked for me. Hope it helps you too.
