How to populate a dropdown from database table using MVC? [duplicate]

Add the List to your model:

public List<string> DropDownList= new List<string>();

and then in your model create a function to load the data for the DropDownList from the database:

public void GetDropDownList()
{

//Pass your data base connection string here 
using (SqlConnection c = new SqlConnection(cString))
//Pass your SQL Query and above created SqlConnection object  "c"
using (SqlCommand cmd = new SqlCommand("SELECT Column1 FROM Table", c))
{
    using (SqlDataReader rdr = cmd.ExecuteReader())
    {
        while (rdr.Read())
        {

         DropDownList.Add(rdr["Column1"].ToString())

        }
    }
}
}

and then in Controller finally, you need to send your model to the view:

//Create object of your Model of controller
 Model objModel = new Model();
 //Call function to  load the data for the DropDownList
 objModel.GetDropDownList();
 //return view with your object of model
 return View(objModel);

Now in the Razor you can display this:

    @Html.DropDownListFor(m => Model.DropDownList);
