Null Values for fields

[Santhosh]

hi all,

I am using forward mapping, I am date field, in some cases i need to set the null value for that,

How can specify this property using Openaccess.

My Task Schema is 

public class Tasks
    {
        public Tasks()
        {
            Assignee = new Resource();
            resource = new Resource();
            duration = 0;
            Edits = new List<TaskEdits>();
        }

        public Guid tuid = Guid.Empty;
        private string name = string.Empty;
        private string description = string.Empty;
        private Resource assignee;
        private Resource resource;
        private DateTime startDate = DateTime.MinValue;
        private int duration;
        private string project_name = string.Empty;
       
        [Telerik.OpenAccess.Depend()]
        public  IList<TaskEdits> edits = null;
        public string Name
        {
            get
            {
                return name ;
            }
            set
            {
                name = value;
            }
        }
        public string Description
        {
            get { return description; }
            set { description = value; }
        }
        public Resource Assignee
        {
            get
            {
                return assignee;
            }
            set
            {
               assignee = value;
            }
        }
        public DateTime StartDate
        {
            get
            {
                return startDate;
            }
            set
            {
                startDate = value;
            }
        }
        public int Duration
        {
            get { return duration; }
            set { duration = value; }
        }
        public Resource Resource
        {
            get { return resource; }
            set { resource = value; }
        }
        public string Project_Name
        {
            get{ return project_name;}
            set { project_name = value;}
        }
        public Guid TUID
        {
            get{ return tuid;}
            set { tuid = value; }
        }
        public IList<TaskEdits> Edits
        {
            get { return edits; }
            set { edits = value; }
        }
    }

 

thanks in advance

Hi Santosh,

You can declare the persistent field as a Nullable<DateTime>

for example

private Nullable<DateTime> startDate;

Hi hgsdc,

What Henrik provided is correct. You can as well put a question mark after the type of the field. This will mark it as nullable thus enabling you to insert nulls when ever you need to do so. Here is an example:

private DateTime? startDate;
