Answer 1

if you want to get city or dist list in a drop down list please see the following code
1) Remove your code
2) Create one Model like this
3) if this drop down is used in more than one page CREATE ONE CONTROLLER like CommanController
4) write one method in this controller
See Below code
First need to create Model like this
public class Industry
{
public string Id { get; set; }
public string industryName { get; set; }
public string regexindustry { get; set; }
}
public class IndustryModel
{
public SelectList industryList { get; set; }
}
In Controller
Two Step 1 is Create one method it return type is List
and Call this method in any ActionReslut with the use of object
ViewBag.list=obj.getIndustryList();
public List<Industry> getIndustryList()
{
List<Industry> objindustry = new List<Industry>();
var connString = new SqlConnection(ConfigurationManager.ConnectionStrings["connectionString"].ConnectionString);
SqlCommand sqlComm = new SqlCommand("sp_selIndustryMaster", connString);
connString.Open();
sqlComm.CommandType = CommandType.StoredProcedure;
SqlDataReader sqldr = sqlComm.ExecuteReader();
int count = 0;
while (sqldr.Read())
{
if (count == 0)
{
objindustry.Add(new Industry { Id ="", industryName = "Select Industry" });
count++;
}
else
{
objindustry.Add(new Industry { Id = Convert.ToString(sqldr["industryCode"]), industryName = sqldr["subindustry"].ToString() });
}
}
return objindustry;
}
IN VIEW
#Html.DropDownListFor(model => model.txtindustry, new SelectList(ViewBag.List, "Id", "industryName", 0))
please use it your problem may be solve,
