Hi,

I use a date and time picker to find transaction( From date & To date)

I am having the issue that not all the transaction are displaying because of the time portion of the dateandtime.
But what i need is simply to display all transactions of the dates between datefrom and Enddate regardless of the time.

And i need it in object format not string format.

this is what i use :

CSS

DateTime FromDate =  DateTime.Now;

DateTime EndDate = DateTime.Now;

C#

var Transaction = (from c in context.JobCards
                   where (c.TransDateRequired > FromDate) && (c.TransDateAdded < EndDate)
                   select c).ToList();

I Also tried to truncate the time

C#

var Transaction = (from c in context.JobCards
                   where (EntityFunctions.TruncateTime(c.TransDateRequired) > EntityFunctions.TruncateTime(FromDate)) && (EntityFunctions.TruncateTime(c.TransDateRequired) < EntityFunctions.TruncateTime(EndDate))
                   select c);

With the truncate time i get following error

LINQ to Entities does not recognize the method 'System.Nullable`1[System.DateTime] TruncateTime(System.Nullable`1[System.DateTime])' method, and this method cannot be translated into a store expression<br />

thanks in advance for any help.

You could build your query by using lambda expression like in the next example and should work:

C#

var Transaction = context.JobCards.Where(c => EntityFunctions.TruncateTime(c.TransDateRequired) > EntityFunctions.TruncateTime(FromDate)) && (EntityFunctions.TruncateTime(c.TransDateRequired) < EntityFunctions.TruncateTime(EndDate)));

Try this:

C#

//Since date columns accepts null in your db table
//Make it nullable
DateTime ?FromDate =  DateTime.Now;
 
DateTime ?EndDate = DateTime.Now;

var Transaction = (from c in context.JobCards 
                                    where (c.TransDateRequired >= FromDate 
                                        && 
                                    c.TransDateAdded <= EndDate)
                                    select c).ToList();

Hi Amy,

Thanks for the help.

I had the >= in the transaction var and the database does allow null.
the database field is dateandtime.

the problem is if a transaction is lets say at 09:00 the previous day and you try to retreive a transaction at 10:00 it doesnt import the transaction because of the time that is before the current time.

and what i am trying to do is ignore the time and use only date from a dateandtime table in the database.

What ive done is formatted selection dateandtime so that time is always 12:00 AM,

Now on date from it will use selected date and enddate it will use date +1 day up to 12:00 AM.

so selecetion will only be date between selections.

Thanks for help and suggestions
