Question

Problem casting current object in a List collection

Asked by: bowemc

Hi,

I have a UserController Class which contains a list of all my Users : public List<User> _users = new List<User>();

I've bound several fields on my GUI to the List and application users can iterate through the list of users with all fields changing in synch

            UserController _userController = new UserController();
            cboUserList.DataSource = _userController.Users();
            cboUserList.DisplayMember = "ID";
            txtID.DataBindings.Add("Text", _userController.Users(), "ID");
            txtName.DataBindings.Add("Text", _userController.Users(), "FullName");
            txtPhone.DataBindings.Add("Text", _userController.Users(), "PhoneExternal");

However, how can I get the current / active / live User oject? I thought ....

    User currentUser = (User) _userController.Users();

But that procues the error

   Cannot convert type 'System.Collections.Generic.List<Wingman.Model.User>' to 'Wingman.Model.User'      

Thanks for your help

Since _userController.Users(); returns a collection of Object you cannot convert it to a single object.

To get the current or active object, you will need to obtain this from the UI control that is manipulation the objects. For instance if you had the users within a dropdownlist having being bound in the order as they appear on the list then you would do the following:

User user = _userController.Users()[ddlExampleList.SelectedIndex]
