check if number of days has passed since a date

Question

I am trying to check if a certain number of days has passed since a date and if it has then change the color of the grid row. So if the date is 12/11/2016 and I want to check if 10 days has passed since that date.

if (dt.Date > dt.Date.AddDays(10))
{
     e.Item.Style.Add("background-color", "#C400F9");
     break;
}

So adding 10 days to the 12th would be the 22/11/2016 and since today is the 23/11/2016 that means 10 days has passed. But all rows in the grid are changing to the color. Do I need to add another if statement to compare the date + the days passed to today's date?

Answer 1

Did you mean to use today's date? If so, that's DateTime.Now :

if (DateTime.Now > dt.Date.AddDays(10))

At the moment you are comparing dt.Date against same date plus 10 days - as others noted, this will never be met.

Update. As Tim suggests in comments, using DateTime.Today might be more appropriate.

Answer 2

DateTime d1;
DateTime d2;

if((d1 - d2).TotalDays == 10)
{
  //some code
}

Answer 3

Your problem is in your comparison. You're trying to figure out if dt is bigger than dt + 10. Obviously it will never be true.

Answer 4

Your comparison will never be true, it's like doing:

If (10 > 10 + 10)...

What you want to do is compare 10 days after the date with today using DateTime.Now

Answer 5

if (DateTime.Now.Date> dt.Date.AddDays(10).Date)
{
    e.Item.Style.Add("background-color", "#C400F9");
    break;
}

Answer 6

if (DateTime.Now.Date > dt.Date.AddDays(10))
{

}

Answer 7

Can you Try this, Below X is date that you want to compare with(it may come form db or hardcoded date)

if (X > dt.Date.AddDays(10))
        {
            e.Row.Attributes.Add("background-color", "#C400F9");
        }
