![]() ![]() To apply configuration options only to selected calendar links, you can use calendar link parameters. There you can choose to adjust the Start Date of your calendar.įor the First day of option, you can choose the first day of the current quarter, month, or year, or select a specific month.įor Past Date and Future Date, you can select the number of days in the past or future: In this scenario, it would make sense to select the start day of the conference as the default calendar view date.Ĭalendar administrators can set the default calendar view date: go to Settings > Date & Time. Imagine a calendar used to plan a conference program. With Teamup, it is easy to change the default calendar start date. In some cases, however, it is preferable to choose a past or future date as the default calendar view date. I hope this helps to clear up any confusion.In most cases it makes sense to open your calendar with the current date in view. Using ADO.NET to get the data from the database, it will look a bit different to the way it was done above (assigning null instead of DateTime.MinValue): BlogPost blogPost = new BlogPost() īlogPost.DateModified = sqlDataReader.IsDBNull(0) ? (DateTime?)null : sqlDataReader.GetFieldValue(0) īlogPost.DatePublished = sqlDataReader.GetFieldValue(1) DateModified is when a post is modified, so it doesn't have to contain a value, but can contain a value. DatePublished is when the post was published to the website and has to contain a date/time value. It has many different fields/properties but I chose only to use two for this example. My scenario is that I have a BlogPost class. The DateTime variable type cannot be set to null, it needs a value, in this case I am going to set it to the DateTime's minimum value if there is no value. Let me demonstrate my first point using an example. This way you can set your date/time variable to null if you don't have a variable to it. Mark your date/time variable as nullable. ![]() Decide on using min or max and stick with it. Just make sure that you are consistent site-wide when checking your date/time values. ![]() You can assign a maximum date/time value as well - whichever way suits you. So what you are looking to do is one of two things (there might be more but I can only think of two):Īssign a minimum date/time value to your variable if you don't have a value for it. If you mark a date/time variable as nullable then only can you assign a null value to it. it needs to contain a value, it cannot be blank or contain nothing. ![]() Given the nature of a date/time data type it cannot contain a null value, i.e. Sorry if you disagree.Įdit: Removed a third option as it was a bit overly specific and case dependent. There are a few ways, number 1 is by FAR the best and 2 is "dude why".ĭateTime date = () //WorksĭateTime date = myNullableObject.ToUniversalTime() //Not a datetime object, failsĬonverting the nullable object to datetime using Convert.ToDateTime(),ĭateTime date = Convert.ToDateTime(myNullableObject).ToUniversalTime() //works but why.Īlthough the answer is well documented at this point, I believe the usage of Nullable was probably worth posting about. So - now the issue comes to mind as to the best way to access the DateTime object. This container has its own properties which you can call that will provide access to the aforementioned DateTime object after using the correct property - in this case Nullable.Value - you then have access to the standard DateTime members, properties etc. I'll try and explain.īy using Nullable you're basically wrapping DateTime in a container (thank you generics) of which is nullable - obviously its purpose. Just be warned - When using a Nullable its obviously no longer a 'pure' datetime object, as such you cannot access the DateTime members directly. ![]()
