System.Web.HttpException was occuerd. I want to know What is the reason behind this error and what is the best method to form submit using partail View.

Answer 1

Id have to agree with Sandip's answer here, but to elaborate ..
#using (Html.BeginForm("AddComment", "Home"))
{
//Content to send to the server-side
}
As long as your model in your partial view points to your 'Comment' object, then this should work fine when using #Html.EditorFor(). In your controller, your already waiting for your 'Comment' object to be populated. So on Post, when the submit is clicked, it will populate that object.
Hope this helps.

Answer 2

#using (Html.BeginForm("AddComment", "Home"))
{
}
