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 }); }
Statements are roughly equivalent to sentences in natural languages. A statement forms a complete unit of execution. The following types of expressions can be made into a statement by terminating the expression with a semicolon ( ; )
Avalue = 8933.234; // assignment statement
Avalue++ ; // increment statement
System . out . println (avalue); // method call statement
Integer integerobject = new integer (4); // object creation statement
In addition to these kinds of expression statements, there are two other kinds of statements. A declaration statement declares a variable. You’ve seen many examples of declaration statement.
Double avalue = 8933.234; // declaration statement
A control flow statement regulates the order in which statements get executed. For loop and if statements are both examples of control flow statements.
- Assignment expressions
- Any use of ++ or - -
- Method calls
- Object creation expressions
These kinds of statement are called expression statement. Here are some example of expression statements :
Avalue = 8933.234; // assignment statement
Avalue++ ; // increment statement
System . out . println (avalue); // method call statement
Integer integerobject = new integer (4); // object creation statement
In addition to these kinds of expression statements, there are two other kinds of statements. A declaration statement declares a variable. You’ve seen many examples of declaration statement.
Double avalue = 8933.234; // declaration statement
A control flow statement regulates the order in which statements get executed. For loop and if statements are both examples of control flow statements.
Block
A block is group of zero or more statements between balanced braces and can be used anywhere a single statement is allowed. The following listing shows two blocks.
If (character . I suppercase(achar))
{
Labe l1 . settext (“the character” + achar + “is upper case .”) ;
}
Else
{
Labe l1. Settext (“the character” + achar + “is lower case .”) ;
Label2. Settext(“thank you”) ;
}
{
Labe l1 . settext (“the character” + achar + “is upper case .”) ;
}
Else
{
Labe l1. Settext (“the character” + achar + “is lower case .”) ;
Label2. Settext(“thank you”) ;
}
Character.isLowerCase( ) tests whether a character is in lowercase.
Character.isUpperCase( ) tests whether a character is in uppercase.
Character.toLowerCase( ) converts the case of a character to lowercase
Character.toUpperCase( ) converts the case of a character to uppercase
First Block:
Character.isUpperCase( ) tests whether a character is in uppercase.
Character.toLowerCase( ) converts the case of a character to lowercase
Character.toUpperCase( ) converts the case of a character to uppercase
First Block:
If (character.isUpperCase(achar))
{ // block1 begins
Label1.Settext (“ The character “ + achar + “ is upper case.”) ;
} // end of block 1
Else
{ // block1 begins
Label1.Settext (“ The character “ + achar + “ is upper case.”) ;
} // end of block 1
Else
Another Block:
{ // block2 begins
Label1.Settext(“ The character “ + achar + “ is lower case . “) ;
} // end of block2
{ // block2 begins
Label1.Settext(“ The character “ + achar + “ is lower case . “) ;
} // end of block2
See, the beginning and end of blocks have been marked.
A Block is a group of zero or more statements between balanced braces and can be used anywhere a single statement is allowed.
In this book, we shall be following conventional style where opening brace of the block is not put in a separate line, rather it is placed in continuation with the previous statement (whose part the block is).
For instance, rather than showing
If (a > b) { : }
If (a > b) { : }
We shall be writing
If (a > b) { : }
Opening brace of the block in continuation with previous statement
If (a > b) { : }
Opening brace of the block in continuation with previous statement
