I have a DataTimePicker and a ComboBox on a TabControl. They are on Tab2 which is not initially displayed when the form is loaded. There is a button to add a new record on the form and when it is pressed default values are set for many of the controls. However, since these two controls are not visible at the time the subroutine is run to set the default values, the values are never set. Here is my code below. It is fairly simple but how do I set the value of these controls depite them not being shown? Should I set the value on the dataset or tableadapter 
  Private Sub OrderHeaderBindingNavigatorAddNewItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OrderHeaderBindingNavigatorAddNewItem.Click
        Try
            Me.OrderHeaderBindingSource.AddNew()
            Me.OrderTypeComboBox.SelectedValue = My.Settings.DefaultSalesOrderType
            Me.EmployeeComboBox.SelectedValue = My.Settings.DefaultSalesPerson
            Me.FOBPointComboBox.SelectedValue = My.Settings.DefaultFOBPoint
            Me.OrderDateDateTimePicker.Value = Now
            Me.PrepDateTimePicker.Value = Now
            Me.RentFromDateTimePicker.Value = Now
            Me.RentToDateTimePicker.Value = Now.AddDays(7)
            Me.SaleRequiredDateDateTimePicker.Value = Now
        Catch ex As System.Exception
            System.Windows.Forms.MessageBox.Show(ex.Message)
        End Try
    End Sub
 instead?
