问题描述

hii,



  private   void  BusinessYearMonthAndDateDropDown()
{
DateTimeFormatInfo info = DateTimeFormatInfo.GetInstance( null );

for int i = 1 ; i < 13 ; i ++)
{
drpBusinessStartMonth.Items.Add( new ListItem(info.GetMonthName(i),i.ToString()));

}

for int i = 1 ; i < = 31 ; i ++)
{
drpBusinessStartDate.Items.Add(i.ToString());
}
}

hii,

private void BusinessYearMonthAndDateDropDown()
       {
           DateTimeFormatInfo info = DateTimeFormatInfo.GetInstance(null);

           for (int i = 1; i < 13; i++)
           {
               drpBusinessStartMonth.Items.Add(new ListItem(info.GetMonthName(i), i.ToString()));

           }

           for (int i = 1; i <= 31; i++)
           {
               drpBusinessStartDate.Items.Add(i.ToString());
           }
       }




This is my code.. does this code stores datavalue field property . if i am adding moths into my list .. can i get its value property as 1 to 12 as well .. if not how can i set that in my code?
