Table is nullable DateTime, but DataSet throws an exception?

Question

I\'m attempting to use the DataSet designer to create a datatable from a query. I got this down just fine. The query used returns a nullable datetime column from the datab

Thanks this solved my similar issue : Here is the code. In case of this question

Isevent_start_date()

would return whether or not the field is null.

In my case: I had a similar problem and I used the following solution

            //Table's Name is Efforts,
            //Column's name is Target
            //So the dataset would automatically generate a property called IsTargetNull() which can be used to check nullables
            //Create an Adaptor
            EffortsTableAdapter ad = new EffortsTableAdapter();
            ProjectDashBoard.Db.EffortsDataTable efforts = ad.GetData();
            DataColumn targetColumn = new DataColumn();
            targetColumn = efforts.TargetColumn;

            List targetTime = new List();
            foreach (var item in efforts)
            {

                //----------------------------------------------------
                //This is the line that we are discussing about : 
                DateTime? myDateTime = item.IsTargetNull() ? null : (DateTime?)item.Target;
                //----------------------------------------------------

                targetTime.Add(myDateTime);

            }
