I use code such as this to clear out the values in several text boxes:

```
Private Sub RibbonButtonInsert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RibbonButtonInsert.Click

    UpdateDataSource()

    StudentsBindingSource.ResetBindings(True)
    DatePickerDateOfBirth.Value = ""
    RichEditBoxForeName.Focus()
    StudentsBindingSource.AddNew()
End Sub

```

Because the date picker control did not clear out like the other controls did, I tried:

```
    DatePickerDateOfBirth.Value = ""

```

but it does not clear out. Instead, I get an "InvalidCastException".

Can you show me what coding I need to properly clear out the value in this data picker?
