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
Definition : It is possible to make a pointer to point to another pointer variable. A variable which contains address of a pointer variable is called pointer to a pointer. For example, consider the following declarations:int a;
int *p1;
int *p2;
- The first declaration instructs the compiler to allocate the memory for the variable a in which integer data can be stored.
- The second declaration tells the compiler to allocate a memory for the variable p1 in which address of an integer variable can be stored.
- The third declaration tells the compiler to allocate a memory for the variable p2 in which address of a pointer variable which points to an integer can be stored. The memory organization for the above three declaration is shown below:
Example: Memory organization after executing following assignment statement:
a=10;
p1=&a;
p2=&p1;
The memory organization after executing the statement a=10 is shown below:
The memory organization after executing the statement p1=&a is shown below:
The memory organization after executing the statement p2=&p1 is shown below:
The data item 10 can be accessed using three variables a, p1 and p2 as shown below:
a refers to the data item 10
*p1 Also refers to the data item 10. Here, using p1 and only one indirection operator, the data item 10 can be accessed.
**p2 Also refers to the data item 10. Here, using p2 and two indirection operators the data item 10 can be accessed (i.e., *p2 refers to p1 and **p2 refers to a)
