Question

I am trying to show multiple values in dropdownlist text. The example is given following.

SelectList(Parts, "pno", "pcode"+"pname")

where

pno is Part number.

pcode is part code.

pname is part name

Now please tell me how can i concatenate part code and name with out using viewmodel(I want to do it using domain model).

According to microsoft documentation, SelectList(IEnumerable, String, String) Initializes a new instance of the SelectList class by using the specified items for the list, the data value field, and the data text field.

In order to do this, you would want to concatenate the name into a new property on your model. The below stack overflow answer with 8 ups is my favorite way to do this.

How can I combine two fields in a SelectList text description?

In your case, it would look something like this…

public class Model
{
    public string pcode { get; set; }
    public string pname { get; set; }
    public string ConcatDescription { get; set; }

    public string ConcatDescription 
    {
        get 
        {
            return string.Format("{0} {1}", pcode , pname );
        }
    }
}

Then you can just call that property directly.

SelectList(Parts, "pno", "ConcatDescription ")
