Populating a List box with recent dates

I am having a interesting issue. I work for a University's Career
Services department. We collect data from recent grads. I am
recreating the online survey we use. I am trying to populate the
graduation date with 4 dates. May **, June **, August **, December **.
The "**" represents the year of graduation. To prevent having to
constantly update this survey I'd like to dynamically create this
values. So at page load I want it to check the server time and only
show the months from the past year. IE since Today is June 07 the
values would read June 07, May 07, December 06, August 06. Then in
August It would read August 07, June 07, May 07, December 06. Etc... I
am trying to think of a clever way to do this and just can not do
this. Anyone have an idea?"djjohnst" <djjohnst@.gmail.com> wrote in message

List<DateTime> lstDates = new List<DateTime>();
DateTime dtmStart = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);
while (lstDates.Count < 4)
{
if (dtmStart.Month == 5
|| dtmStart.Month == 6
|| dtmStart.Month == 8
|| dtmStart.Month == 12)
{
lstDates.Add(dtmStart);
}
dtmStart = dtmStart.AddMonths(-1);
}

How about something like...
DateTime dt = DateTime.Today();
for (int iLoop = 0; iLoop < 4; iLoop++)
{
ddlMyDropDown.Items.Add(new ListItem(String.Format("{0:MMM yy}",
dt)));
dt = dt.DateAdd("MM", -3, dt);
}

Suppose you start today, what are the four dates which your code will add to
the DropDownList...?

Just a bit of modification to Mark's code to output it as djjohnst was looki
ng
for, in the "June XX" format):
List<String> lstDates = new List<String>();
DateTime dtmStart = new DateTime(DateTime.Now.Year, DateTime.Now.Month,
1);
while (lstDates.Count < 4)
{
if (dtmStart.Month == 5
|| dtmStart.Month == 6
|| dtmStart.Month == 8
|| dtmStart.Month == 12)
{
lstDates.Add(dtmStart.ToString("MMMM yy"));
}
dtmStart = dtmStart.AddMonths(-1);
}
ddlGradDates.DataSource = lstDates;
ddlGradDates.DataBind();
- Converted it from a list collection of DateTimes to Strings; maybe a KVP
to keep the "data" and presentation apart may be a solution if the two need
to be different.
- Added the MMMM yy to output the long Month name and short year.
HTH.

True enough - I took the final formatting "as read", and assumed that the
it was the actual date generation that was causing the OP problems... :-)
