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 }); }
Suppose you have 2D array in the form of x and y axis, You want to access last index of both axis. Now at this time, you can consider x as row and y as column. Here we use GetUpperBound ( ) method for accessing last index of array. Lets take an example, in which we will pass 0 and 1 in the GetUpperBound ( ) method. Here 0 for first axis and 1 for second axis.
<form id="form1" runat="server">
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Clike"
BackColor="#99CCFF" />
<div>
<asp:Label ID="Label1" runat="server" BackColor="Yellow"></asp:Label>
</div>
</form>
Code Behind
protected void Button1_Click(object sender, EventArgs e)
{
{
string[,] fruits = new string[4, 2]
{
{"Red","Apple"},
{"Orange","Orange"},
{"Yellow","Banana"},
{"Green","Mango"},
};
int rows = fruits.GetUpperBound(0);
int columns = fruits.GetUpperBound(1);
Label1.Text = "index of last element of first dimension [0] in fruits array: " + rows.ToString();
Label1.Text += "<br />index of last element of second dimension [1] in fruits array: " + columns.ToString();
Label1.Text += "<br /><br />two dimension fruits array elements.........<br />";
for (int currentRow = 0; currentRow <= rows; currentRow++)
{
for (int currentColumn = 0; currentColumn <= columns; currentColumn++)
{
Label1.Text += fruits[currentRow, currentColumn] + " ";
}
Label1.Text += "<br />";
}
}
Code Generate the following output
<form id="form1" runat="server">
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Clike"
BackColor="#99CCFF" />
<div>
<asp:Label ID="Label1" runat="server" BackColor="Yellow"></asp:Label>
</div>
</form>

int rows = fruits.GetUpperBound(0);

{

}
Label1.Text += "<br />";
}
}
