Disable backspace key in HTML form using Jquery in simple steps. While user enters data into application if user accidentally  press backspace button then it will redirect to previous page and all entered data would be lost. to eliminate this event we can disable the backspace key using Jquery. Following is the JQuery script tag you can add to the web page $(document).keydown(function (e) { var nodeName = e.target.nodeName.toLowerCase(); if (e.which === 8) { if ((nodeName === 'input' && e.target.type === 'text') || nodeName === 'textarea') { // do nothing } else { e.preventDefault(); } } }); The above code can be used seamlessly with any web technology you are using.

Angular User Session Timeout example step by step

This functionality let the user know that their session is about to expire and that they would be logged out if they didn’t take action. I have written this functionality in Angular for my latest application.  If you are new to Angular 6 then read my article about Setting up Angular 6 step by step before jump to this article to get handy in Angular 6. Dealing with timers in Angular can be significantly different when using React components and subscriptions. The basic premises remains the same, though. We’ll have a service with a timer that will provide a Subject to which consumers of the service can subscribe. A React Subject provides an easy mechanism to trigger a “next” subscription to alert consumers that the timer has expired.   import { Injectable } from '@angular/core'; import { Observable, Subject, Subscription, BehaviorSubject} from 'rxjs/Rx'; @Injectable() export class IdleTimeoutService { private _count: number = 0;

-
I am going to demonstrate in this article about importing CSV file data into datatable and then bind that data to Asp.net gridview control. I have tried to make code simpler and less line of code.

After that create function which returns string[] private IEnumerable<string[]> GetAllDataFromCSVFile(string FileName) { string str; using (StreamReader rd=new StreamReader(FileName)) { while ((str = rd.ReadLine()) != null) { yield return str.Split(','); } } } Create another function which returns final data-table with CSV File data private DataTable GetCSVData(string FileName) { var values = GetAllDataFromCSVFile(FileName); DataTable dt = new DataTable(); int j=0; foreach (var

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
