Question

I have created mvc3 application.
where using EF to populate dropdownlist from tables.

now I have two dropdownlists on my index.cshtml each populating from different tables.

code index.cshtml:

i have taken model as entity as it is having both my tables table1 and table2

@model Mapping.Models.mydataEntities1

but problem is here i’m not able to select values from both tables. 🙁

like following code is for only working when i give
model @model Mapping.Models.table1

but need to select values into two dropdown from different tables

@using (Html.BeginForm())
{
    @Html.DropDownListFor(
        x => x.CategoryId, 
        new SelectList(Model.Categories, "Value", "Text"),
        "-- Select category --"
    )
    <input type="submit" value="OK" />
}

How can i do this?

I have used EF

 public partial class mydataEntities1 : DbContext
    {
        public mydataEntities1()
            : base("name=mydataEntities1")
        {
        }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            throw new UnintentionalCodeFirstException();
        }

        public DbSet<table1> table1 { get; set; }
        public DbSet<table2> table2 { get; set; }
    }
}

I’m not an EF user, but assuming that your model is populated and works correctly
the following code should works

@Html.DropDownListFor(
    x => x.table1.CategoryId, 
    new SelectList(Model.table1.Categories, "Value", "Text"),
    "-- Select category --"
)

@Html.DropDownListFor(
    x => x.table2.CategoryId, 
    new SelectList(Model.table2.Categories, "Value", "Text"),
    "-- Select category --"
)

But I strongly reccomend you to create a ViewModel to expose your data to the View and not your domain entities or directly the repository.
