Adding form to view in ASP.NET MVC

Question

I have blog model with public ICollection<Comment> Comments { get; set; } public ICollection<Comment> Comments { get; set; } public ICollection<Comment> Comments { get; set; } and comment model. I have created view for article (Details view) and I want to show everything from model blog (not problem) and comments to article to and after comments then show form for adding comment to blog (not in other page, I want it in the view with blog).

public class BlogPost
{
    public int BlogPostID { get; set; }
    public string Title { get; set; }    
    public string Body { get; set; }   
    public ICollection<Comments>Comments {get;set;}
}

public class Comments
{
    public int BlogPostID { get; set; }  
    public string Comment { get; set; }
    public DateTime dateTime { get; set; }  
    public virtual BlogPost BlogPost { get; set; }
}

View

@model projectMvc.Model.BlogPost;

<div>
    
    <hr />
    <dl class="dl-horizontal">
        <dt>
            @Html.DisplayNameFor(model => mode.Title)
        </dt>
        <dd>
            @Html.DisplayFor(model => model.Title)
        </dd>
        <dt>
            @Html.DisplayNameFor(model => model.Body )
        </dt>
        <dd>
            @Html.DisplayFor(model => model.Movie.Body )
        </dd
    </dl>
</div>
@if (Model.Comments != null)
{
    foreach (var comment in Model.Comments)
    {
        @Html.Partial("_Comment", comment)
    }
}

It shows the blog data and there is partial view for all comments to blog. And now I am not sure how to add form for adding comments. Thank you.

To add comments you can add below syntax in your view for displaying textbox for adding comment and button for submitting comments

<div class="AddComment" style="margin-left: 30%;  margin-bottom: 5px; margin-top: 8px;">  
                   <input type="text" id="@string.Format("{0}_{1}", "comment", post.BlogPostID)" class="form-control"  placeholder="Add a Comment ..."  style="display: inline;" />  
                   <button type="button" class="btn btn-default addComment" data-id="@post.PostID"><span class="glyphicon glyphicon-comment" aria-hidden="true"></span></button>  
               </div>  
  
           </div>   

After that on click of button you can call appropriate action from the controller using ajax

$('.addComment').on('click', function () {  
  
                var postId = $(this).attr('data-id');  
                var commentMsg = $('#comment_' + postId).val();  
                var dateTimeNow = new Date();  
                  
                //alert('Hello');  
                var comment = {  
                    CommentMsg: commentMsg,  
                    CommentedDate: dateTimeNow.toLocaleString()  
                };  
  
                $.ajax({  
  
                    type: 'POST',  
                    url: '@Url.Action("AddComment", "Comments")',  
                    data: { comment, postId },  
                    success: function (response) {  
  
                        $('div[class=allComments_' + postId + ']').remove();  
  
                        var allCommentsArea = $('<div>').addClass('allComments_' + postId);  
                        allCommentsArea.html(response);  
  
                        allCommentsArea.prependTo('#commentsBlock_' + postId);  
                         
                    },  
                    error: function (response) {  
                        alert('Sorry: Something Wrong');  
                    }  
  
                });  
  
            });
