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 }); }
In this article, I will show you how to merge two data column into single one. First of all, bind DataTable with four columns i.e SNO, FirstName, LastName and City. Bind the DataTable source with GridView. Now, You can change the binding view of Gridview using OnRowDataBound event.

g1.DataSource = dt;
g1.DataBind();

{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[1].Text = string.Format("{0}-{1}", DataBinder.Eval(e.Row.DataItem, "FirstName"), DataBinder.Eval(e.Row.DataItem, "LastName"));
}
}
}
