Solution 2

Let say you have two dropdownlists named ddl1 and ddl2, to insert the selected values of these 2 dropdownlists to database,

sql = "INSERT INTO tablename (column1, column2) Values(@0,@1)";
command = new SqlCommand(sql);
command.Parameters.AddWithValue("@0",ddl1.SelectedValue);
command.Parameters.AddWithValue("@1",ddl2.SelectedValue);
command.ExecuteNonQuery();

i tried parameters ,but i am not able to send value through query
string insquery = "insert into tbl_paper (paper_name,year_id,course_id,streame_id,semester_id)values (@0,@1,@2,@3,@4))";

objclsvrb.objsqlcomd = new SqlCommand(insquery);

// objclsvrb.objsqlcomd.Parameters.Parameters.Add("@ID", SqlDbType.Int);

//command.Parameters["@ID"].Value = customerID;

objclsvrb.objsqlcomd.Parameters.Add("@0", SqlDbType.VarChar);
objclsvrb.objsqlcomd.Parameters["@0"].Value = txt_filename.Text;

objclsvrb.objsqlcomd.Parameters.Add("@1", SqlDbType.VarChar);
objclsvrb.objsqlcomd.Parameters["@1"].Value = DD_course.SelectedValue;

objclsvrb.objsqlcomd.Parameters.Add("@2", SqlDbType.VarChar);
objclsvrb.objsqlcomd.Parameters["@2"].Value = DD_streame.SelectedValue;

objclsvrb.objsqlcomd.Parameters.Add("@3", SqlDbType.VarChar);
objclsvrb.objsqlcomd.Parameters["@3"].Value = DD_year.SelectedValue;

objclsvrb.objsqlcomd.Parameters.Add("@4", SqlDbType.VarChar);
objclsvrb.objsqlcomd.Parameters["@4"].Value = DD_semester.SelectedValue;

int temp = Convert.ToInt32(objclsfun.FnExeNonQuery(insquery));
if (temp == 1)
{
Response.Write("added");

}

public int FnExeNonQuery(string query)
{

objclsvrb.objsqlcon = new SqlConnection(objclsvrb.constring);
objclsvrb.objsqlcomd = new SqlCommand(query, objclsvrb.objsqlcon);
objclsvrb.objsqladapter = new SqlDataAdapter(objclsvrb.objsqlcomd);
objclsvrb.objds = new DataSet();
objclsvrb.objsqlcon.Open();
//objclsvrb.objSqladp.Fill(objclsvrb.objds);
int retIntValue = Convert.ToInt32(objclsvrb.objsqlcomd.ExecuteNonQuery());
objclsvrb.objsqlcon.Close();
return retIntValue;
}
