Question

Hi I have a the following scenario

Table - Items
    id int (PK),
    name varchar(100)

Table - Category
    id int (PK),
    name varchar(100)

Table - Category_item
    category_id int (FK),
    item_id int (FK)

I’m using Asp.Net MVC and Entitydatamodel.
In the view I have a dropdown list to show the categories and a check boxes to display item.

I want to insert into the Table – Category_item when i select the category and curresponding items.
How can i do it? How can I pass the values from the view to the controller?

Answer 1

The anwser is that it depends. But the general case is (RAZOR)

@Html.DropDownList(category,
db.Categories.Select(cat => new
SelectListItem()
{Text = cat.Name,
Value = cat.Id,
Selected = (false/true)
}).ToList());

You can use Html.DropDownListFor and then the Save action will already be bounded with correct value. ‘db’ is the model context.
