Bootstrap is the most popular HTML, CSS, and JavaScript framework for developing responsive, mobile-first web sites.
In this example i will show how to use Bootstrap Confirm modal in asp.net.This is the most common Scenerio where we want to confirm before we delete any record.Here i will demonstrate how call confirm modal from within gridview link and if user confirms then only record will be deleted.
For the sake of simplicity i have used a class with some data .You can also use database to populate gridview.
Here is the code behind for the same.

Now we will create a webform ConfirmDemo.aspx.using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace BootStrapConfirm { [Serializable()] public class Details { public int Id { get; set; } public string Name { get; set; } public string City { get; set; } public List<Details> GetDetails() { List<Details> Persons = new List<Details>(); Persons.Add(new Details { Id=1,Name= "Rajeev", City="Bangalore" }); Persons.Add(new Details { Id = 2, Name = "Raj Kumar", City = "Chennai" }); Persons.Add(new Details { Id = 3, Name = "Raj", City = "Mumbai" }); Persons.Add(new Details { Id = 4, Name = "Shiva", City = "Pune" }); Persons.Add(new Details { Id = 5, Name = "Lalit", City = "Ahmedabad" }); return Persons; } } }
