I am filtering dataview using my Date Column but the result is not proper because the Field value also stores time, so I want to convert this Date Field to only Date during Filter. How can I achieve this? Here is my code. And the actual value I am getting in the Dataset Field "CreationDate" is a DateTime field which is like
2010-01-21 14:35:25.203
2010-01-22 12:55:18.033
2010-01-26 12:10:06.990
But I only want to neglet time value and want to compare Date only.

or
05-13-2010 23.59.59
What statement would I use to accomplish this?

I've pulling back an entity object from a database and I need to update the date to the DB server's date/time - usually you could accomplish this by setting it with the SQL getDate() function.
How can I accomplish this in the following scenario:
var client = context.client.Where(c=>c.clientID == 1).FirstOrDefault();
// the value needs to be the value of the server's current date, i.e, getDate()... not DateTime.Now
client.someDate = <somevalue>;
context.SaveChanges();
