    This doesn't work as it should.
    It works ok for the first thousand - a comma is inserted after entering 1000 - but when you continue entering numbers after that, it inserts consecutive commas after 2 digits, not 3, so you get something like this: 10,00,000 - where it should be: 1,000,000

    Did you test this with more than 4 digits?

      just replace the regular expression with this:

      var rgx = /(\d)((\d{3}?)+)$/;

Restore the lost focus of Auto post back controls in asp.net update Panel control

-
Problem: We put  autopostback controls like textbox, DropDownList controls inside in update panel to reducing the flickering of the Page.but when user uses tab for entering the details  the focus of the control losts. Web site users who prefer to use keyboard need to use mouse to activate appropriate input box or press TAB multiple times. Solution: Step 1: Save following in js file give any name to it (like MyUpdatePanelFocus.js ) var lastFocusedControlId = ""; function focusHandler(e) { document.activeElement = e.originalTarget; } function appInit() { if (typeof (window.addEventListener) !== "undefined") { window.addEventListener("focus", focusHandler, true); } Sys.WebForms.PageRequestManager.getInstance().add_pageLoading(pageLoadingHandler); Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(pageLoadedHandler); } function pageLoadingHandler(sender, args) { lastFocusedControlId = typeof (document.acti

clone a generic list in C# using extension method

-
In practical situation you need to clone of object so that change in cloned object will not affect the original one. If you need a cloned list with the same capacity you need to do some extra stuff with your user type. I came up with this easy solution using ICloneable interface in your custom type class. The first step you need to implement the ICloneable interface in your class like below. public class MyClassDto : ICloneable { public Int64 Id { get; set; } public string Time { get; set; } public int user{ get; set; } public object Clone() { return new MyClassDto{ Date = this.Date, Id = this.Id, user = this.user}; } } after that you need to add extension method in common class so that you can use it everywhere you want. public static class Extensions { public static List<T> Clone<T>(this List<T> listToClone) where T : ICloneable { return listToClone.Select(item
