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 }); }
CausesValidation: Whether Validation is performed or not , you can check using CausesValidation property,after button click. Bydefault page validation is performed with all control, which is associated with validation control. If CausesValidation is true, page validate all control , which is associated with validation control. If CausesValidation is false , manually validate the control by the user.
Lets Take an Simple Example
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default4.aspx.cs" Inherits="Default4" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><asp:RequiredFieldValidator
ID="RequiredFieldValidator1" EnableClientScript ="false" ControlToValidate ="TextBox1" runat="server" ErrorMessage="Validate your name"></asp:RequiredFieldValidator><br />
<asp:Button ID="Button1" runat="server" Text="Button" CausesValidation="False"
onclick="Button1_Click" />
</div>
