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

Answer 1

I did this to insert value NULL in a DateTime column,

assuming that I have a nullable DateTime column in Database, I retrieved some data from the database in an object called response and I want to insert nullable DateTime value in the DataSet column that called RenewDate:

// create anew row of the same type of your table row
var rw = ds.StudentActionPrintDT.NewStudentActionPrintDTRow();

// check for null value
if(!response.RenewDate.HasValue)
{
  // if null, then the let DataSet to set it null by it's own way 
  rw.SetRenewDateNull();
}
else
{
  // if not null set value to the datetime value
  rw.RenewDate = response.RenewDate.Value;
}
// add the created row to the dateset [DataSetName].[ColumnName].Add[ColumnName]Row([The Created Row]);
ds.StudentActionPrintDT.AddStudentActionPrintDTRow(rw);
