no accessible extension method

Question

The view is not able to get my GridData, not sure why.

The code pass the GridData in the view, but the view page is not able to access GridData object.

UserMaster Models:

namespace Project.Models
{
    public class UserMaster
    {
        [Key]
        public int UserId { get; set; }

        [Display(Name = "First Name")]
        public string FirstName { get; set; }
        [Required]

        [Display(Name = "Last Name")]
        public string LastName { get; set; }
        [Required]
    }

    public class UserMasterList
    {
        public List<UserMaster> GridData { get; set; }
    }
}

Control:

 UserMasterList userMasterList = new UserMasterList();
            List<UserMaster> gl = new List<UserMaster>();

            var userMasterListResult = _context.UserMaster.FromSql("EXECUTE [dbo].[UserMaster_Get] {0}", 0).ToList();

            foreach (var data in userMasterListResult)
            {
                gl.Add(data);
            }

            userMasterList.GridData = gl;
            return View(userMasterList);

View:

 @model Project.Models.UserMaster
           @foreach (var data in @Model.GridData)   {
                <tr>
                    <td>
                        @Html.DisplayFor(modelItem => data.FirstName)
                    </td>
                    <td>
                        @Html.DisplayFor(modelItem => data.LastName)
                    </td>
                </tr>
            }

Error: The code pass the GridData in the view, but the view page is not able to access GridData object.

Answer 1

In your controller you are passing an object with type of UserMasterList, but in your view, model is type of UserMaster so that you should update used model in view as like as below:

@model Project.Models.UserMasterList

Answer 2

in view, you should have

@model Project.Models.UserMasterList
