Question

I have been looking through a bunch of different posts on here and on other sites for adding two dates together, but for some reason everyone wants to use ‘Now’

I would like to know how to add two different dates together when neither of which are now!

I have tried a few things but I am getting casting errors. Also worth noting I am setting it to the value of a dateTime picker on my page.

MaxDate.Value = MinDate.Value + TimeSpan.FromDays(1)
'does not work 
MaxDate.Value = Now + TimeSpan.FromDays(1)
'does work!

If it is not obvious, I have two date pickers on my page and when a radio button is clicked I want to set the ‘End date’ (maxdate.value) to whatever the ‘Start date’ (mindate.value) is, and add one day to it.

Thanks for the help!

Just do this:

MaxDate.Value = MidDate.Value.AddDays(1)

You don’t need create a TimeSpan object for that because the Date type has built-in methods for doing incrementation by day, month, year, minute, etc.

The AddDays method does not alter the original date, it just returns a new Date object with the offset value.

By the way, if you want to subtract a day, there is no MinusDays method, just do x.AddDays(-1).
