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 }); }
There are many controls in the palette tab of NetBeans IDE having specific properties of its own. Those controls can easily be added, resize and delete from the frame, while programming in java. This article have some steps to do these tasks in simple way.
When you can add controls to your frame, you might find strange behavior of IDE regarding component positioning and sizing. (This is because of Free Design layout manager.) In order to have full control on component's positioning and sizing, you need to know about Layout Managers. The layout of components on a frame (or panel) is controlled by a layout manager, which determines the final placement of each component. Layout Managers will be covered in next articles.
Another way of removing a control is:
To resize a control, select it first and then use its sizing handle to resize it. That is, move the mouse pointer over sizing handles. The mouse pointer will change to double-headed arrow (↔). See the fig. Now drag the sizing handle to desired new position and control will be resized.
While adding, laying out and resizing controls on the frame, if you are not happy with the default behavior of rearranging/resizing of the control, then you may done one thing. Before you put any controls on the form, right click your frame in Design View and select Set Layout. From the sub menu that appears, select Absolute Layout.
