List / Show Text Which Timestamp Is > Or < Then Datetime?

Dec 1, 2010

I have a question about lists. So let say i have a list with 2000 objects, object has a text and a timestamp. So i want to return the list and i wan to only show text which timestamp is > or < then datetime.now, that is example, yeah, so how should i do it better, faster? Ofc i can make another newList and then just circle tru the list and add to newly created list(newList) the items that i want to show, comparing the items timestamp, but it might take too much time and resources, is there an easier way? Cuz that list with 2000 objects can become bigger after some time.

C# - Get List Of Months From List<DateTime>?

Aug 20, 2010

I'm using a List in ASP.NET 3.5/C# to filter an existing list of dates (about 20 in total) on a specific month.

So if a user selects a year of 2010 (ddlFromYear.SelectedItem.Text == 2010) then the returned list would consist of only 8 months because we only go up to August.

My question is - how do I output the DateTime as an int, or even preferrably a Month, e.g. "August". That way when I'm binding another DropDown I can list out all the months (January, February...) which as I mentioned would be determined by years (2009, 2010...)

int yearSelected;
bool success = Int32.TryParse(ddlFromYear.SelectedItem.Text, out yearSelected);
if (success)
{
List<DateTime> datesSelected = new List<DateTime>();
datesSelected =

AJAX :: Show/hide The Text Box Depending On The Text Of The Selected Item In The Combo Box?

Nov 13, 2010

I have a .net 3.5 web form with an ajax combo box and a text box inside it. The bombo box is bound to a SqlDataSource.

My requirement is to show/hide the text box depending on the text of the selected item in the combo box. If a particular string, say 'xyz', appears in the text of the selected item, the I will make the text box invisible. I enabled the AutoPostback, made the text box disappear in the SelectedIndexChanged event, and everything worked fine.

However, when users enter their own texts (which are not in the list items), I am unable to show / hide the text box. I've tried the TextChanged event but nothing happens. It seems the event is not trigger after I enter a new text and locate the focus to other place.

is there a way to prevent the user ented text from being inserted into the bombo box?
