Many to Many Relation Popup - model-view-controller

Question

basically from embedded field and new to MVC/ASP.net, learning.
I have 2 entities with Many to Many relation.
It is working fine i am able to assign relation bet
Heading
ween them using checkbox.
I want to implement the following:
On Create page of Entity 1, Relative Entity 2 list is shown in table with Link and Unlink buttons.
Find below Image:
Link button will open up the popup which will show Entity 2 listing which is not there in the relation with the Entity 1.
User will select the required Entity 2 using checkbox and press 'Submit button.
On pressing Submit button, the selected Entity 2 objects are added to the **Entity 2 ** table in the Create view and popup closes.
On Saving create view will save everything with relation.
I hope I'm not asking too much... Not able to judge.
Thanks in advance.

Answer 1

Already Working:
1) I am able to open the model using bootstrap modal popup approach and pass the Entity 2 list to it.
2.) I am able to display the list in table.
To achieve:
1) Populate Entity 2 list in popup view with objects which are not in the Entity 2 table in the main view.
2) Have Checkbox in Popup table for selection.
3) Get the selected Entity 2 row details to main view without posting to controller.
4) Update Entity 2 table in the main view with the selected rows.
5) Save to table when save button is pressed..
Entity 1:
public partial class JobPost
{
public JobPost()
{
this.JobTags = new HashSet<JobTag>();
}
public int JobPostId { get; set; }
public string Title { get; set; }
public virtual ICollection<JobTag> JobTags { get; set; }
}
Entity 2:
public partial class JobTag
{
public JobTag()
{
this.JobPosts = new HashSet<JobPost>();
}
public int JobTagId { get; set; }
public string Tag { get; set; }
public virtual ICollection<JobPost> JobPosts { get; set; }
}
public class TempJobTag
{
public int JobTagId { get; set; }
public string Tag { get; set; }
public bool isSelected { get; set; }
}
View Model:
public class JobPostViewModel
{
public JobPost JobPost { get; set; }
public IEnumerable<SelectListItem> AllJobTags { get; set; }
private List<int> _selectedJobTags;
public List<int> SelectedJobTags
{
get
{
if (_selectedJobTags == null)
{
_selectedJobTags = JobPost.JobTags.Select(m => m.JobTagId).ToList();
}
return _selectedJobTags;
}
set { _selectedJobTags = value; }
}
}
Entity 1 Controller:
// GET: JobPosts/Create
public ActionResult Create()
{
var jobPostViewModel = new JobPostViewModel
{
JobPost = new JobPost(),
};
if (jobPostViewModel.JobPost == null)
return HttpNotFound();
var allJobTagsList = db.JobTags.ToList();
jobPostViewModel.AllJobTags = allJobTagsList.Select(o => new SelectListItem
{
Text = o.Tag,
Value = o.JobTagId.ToString()
});
return View(jobPostViewModel);
}
// POST: JobPosts/Create
// To protect from overposting attacks, please enable the specific properties you want to bind to, for
