     Unfortunately, Microsoft's DateTimePicker control falls drastically short when it comes to being able to bind to data source properties that contain the data type of Nullable(Of Date). So I have created a simple DatePicker control that has a Value property of Nullable(Of Date) that can be bound to datasource properties of the same data type.

This article has accompanying files

				I created a DatePicker library in VB.NET 2005 that can be referenced from any project.

This DatePicker control can be bound to any object property that has a data type of Nullable(Of Date): if a date is selected by the user, then the control returns the date, however, if no date is selected by the user, then it returns Nothing.

Using the DataPicker control is easy and straight-forward. But one important note is that when binding to the DatePicker, it is necessary to set the formattingEnabled property to True.

Here's an example of binding the DatePicker control to an Employee BindingSource:
dpHireDate.DataBindings.Add("Value", _ m_bsEmployee, "HireDate", True)

The "HireDate" property of the Employee class is a Nullable(Of Date) property, and looks like this:
Private m_hireDate As Nullable(Of Date) = Nothing
''' Gets or sets the Nullable HireDate

Public Property HireDate() As Nullable(Of Date)
Return m_hireDate
End Get
Set(ByVal value As Nullable(Of Date))
m_hireDate = value
End Set
End Property

Included is the zipped VS 2005 solution that demonstrates how to use the DatePicker control.

I hope it's helpful to you!
