Solution 2

DateTime.Now.Subtract method expects a DateTime value. You code shall work if you just convert the evaluated statement to DateTime.

Change your code to the one below:

XML

<%#System.DateTime.Now.Subtract(Convert.ToDateTime(Eval("Date")))%>

and it should work.

Hope this helps!

Invalid cast from 'Int32' to 'DateTime'.

It means that your "Date" column returns an integer value from the database.
Check what value does your database return.

Solution 1

Here if you are fetching data from a table and then binding in Data Control then you can simply write query as

select datediff(d,getdate(),date)as date from tablename

if you wanr it in days

other option
in aspx.cs page
is

DateTime t1 = DateTime.Now;
DateTime t2 = seconddate;
int i = DateTime.Compare(t1, t2);
