I want to show Components in a tabs , so first of all create few components. In this project we have three components, First View Component public class AllViewComponent : ViewComponent { private readonly UserManager<ApplicationUser> _userManager; public AllViewComponent(UserManager<ApplicationUser> userManager) { _userManager = userManager; } public async Task<IViewComponentResult> InvokeAsync() { List<StudentViewModel> allUsers = new List<StudentViewModel>(); var items = await _userManager.Users.ToListAsync(); foreach (var item in items) { allUsers.Add(new StudentViewModel {Id=item.Id, EnrollmentNo = item.EnrollmentNo, FatherName = item.FatherName, Name = item.Name, Age = item.Age, Birthdate = item.Birthdate, Address = item.Address, Gender = item.Gender, Email = item.Email }); }
Introduction
Regular expression are used to check whether or not the text matches a certain pattern . The RegularExpressionValidator control validates whether the value in the input control (text box) matches the format specified by the regular expression , such as a US telephone number or a date format . The RegularExpressionValidator control exists within the System.Web.UI.WebControls namespace.
In general , regular expression are made up of text within an embedded code listing that starts with a backslash (\) as well as other control code listing . The following is an example:
\b[A-Za-z]+\b
The code for a word boundary (where a word ends or starts ) is \b and a character class is a set of characters surrounded by [ and ] . This allows you to specify what character you want to accept . So , this regular expression matches a word consisting of uppercase or lowercase letters only. The + sign stands for one or more of , so we matching one or more uppercase and / or lowercase letters here.
for example , the regular expression to determine if the text matches a valid e-mail address is :
Public Property of the RegularExpressionValidator Class
ValidationExpression : Obtains or sets the regular expressions that you want to match data against for validation.
