To reproduce:
- Bind RadDataEntry to an object that has DateTime property.
- Change the value using the FreeFormDateTime mask type (enter 101010).
- The value is not changed.

Workaround:

RadDateTimePicker editor;

void radDataEntry1_EditorInitializing(object sender, EditorInitializingEventArgs e)
{
    if (e.Property.Name == "obj")
    {
        editor = new RadDateTimePicker();
        editor.Format = DateTimePickerFormat.Short;
        editor.DateTimePickerElement.TextBoxElement.MaskType = MaskType.FreeFormDateTime;
        RadMaskedEditBoxElement element = editor.DateTimePickerElement.TextBoxElement.TextBoxItem.Parent as RadMaskedEditBoxElement;
        FreeFormDateTimeProvider provider = element.Provider as FreeFormDateTimeProvider;

        provider.ParsedDateTime += provider_ParsedDateTime;

        e.Editor = editor;
        
    }
}

void provider_ParsedDateTime(object sender, EventArgs e)
{
    editor.Value = (DateTime)(sender as FreeFormDateTimeProvider).Value;
}

To reproduce:
- Add bindingnavigator and data entry bound to a single binding source.
- Change one of the default editors to drop down list which is also bound to a datasource.
- Synchronize the selected value in the binding source CurrentChanged event.
- Press the move to the last item button.
- You will notice that the value is not displayed properly (displayed is the value member not the display member)

Workaround: 
void radBindingNavigator1MoveLastItem_Click(object sender, EventArgs e)
{
    bs.MovePrevious();
    bs.MoveNext();
}

To reproduce:
- Create a binding source and use the following datatable as its datasource:
 static DataTable GetTable()
{
    DataTable table = new DataTable();

    table.Columns.Add("Str", typeof(string));
    table.Columns.Add("Days", typeof(Days));
    
    table.Rows.Add("Value 1", Days.Fri);
    table.Rows.Add("Value 2", Days.Mon);

    return table;
}

- Bind the data entry to the binding source
- You will notice that the enum value is not displayed.

Workaround:
void radDataEntry1_BindingCreating(object sender, BindingCreatingEventArgs e)
{
    if (e.DataMember == "Days")
    {
        e.PropertyName = "SelectedIndex";
    }
}
