SqlCommand cmd = new SqlCommand("proc_get_preference_dropdown", con);
SqlDataAdapter ada = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
ada.Fill(ds);
if (ds.Tables[0].Rows.Count > 0)
{
for (int i = 0; i < ds.Tables[0].Rows.Count;i++ )
{
if (ds.Tables[0].Rows[i]["code"].ToString() == "04") // Set Caste Preference
{
lcaste = new List<Caste>();
Caste obj1 = new Caste();
obj1.decription = ds.Tables[0].Rows[i]["description"].ToString();
obj1.sysId = Convert.ToInt32(ds.Tables[0].Rows[i]["id"]);
//obj1.isChecked = "N";
lcaste.Add(obj1);
obj.lcaste = lcaste;
continue;
}
}
}
return obj;
}
public class Caste
{
public int sysId { get; set; }
public string decription { get; set; }
public string isChecked { get; set; }
}
}
#model Matrimony.Models.RegistrationClass
<tr>
<td>
#Html.LabelFor(model => model.subcaste)
</td>
<td>
#Html.DropDownListFor(model => model.cast_id, new SelectList(Model.lcaste))
</td>
</tr>

Answer 1

Finally I resolved this by adding simple option tags.
<td>
<select name="cast_id">
<option value="0">--Select--</option>
#for (int i = 0; i < Model.lcaste.Count; i++)
{
<option value=#Model.lcaste[i].sysId>#Model.lcaste[i].decription</option>
}
</select>
</td>
The name property of select will get the selected item's value in post method. Accordingly we can handle it in controller. I also added property in my model class to store value as
public int cast_id { get; set; }
public List<Caste> lcaste { get; set; }
