Custom Control in Visual Studio

[Member 9935038]

Hi! I have a custom control. When I add a description to a class or event, I can't see that description in Visual Studio designer. Why? 1) I don't see the description of the class 2) I don't see the Bitmap 3) I don't see the description of the events All that is only in the designer missing. When I access my class inside the code, it is all fine. Has anyone a clue, what is wrong here? Picture Picture2 THX for help :thumbsup:

[ToolboxBitmap(typeof(ComboBox))]
[Description("Ein DropDown Control für I/O-Control GmbH")]
public partial class IOC_DropDown : UserControl
{
// Events

    /// /// Event, wenn das DropDown geschlossen wurde
    /// 
    public event DrowDownClosedEventHandler OnDropDownClosed;

    /// /// Event, wenn das DropDown geöffnet wurde
    /// 
    public event DrowDownOpenedEventHandler OnDropDownOpened;

    /// /// Event, wenn das DropDown geöffnet werden soll
    /// 
    public event DropDownOpeningEventHandler OnDropDownOpening;

    /// /// Event, wenn das DropDown geschlossen werden soll
    /// 
    public event DropDownClosingEvetnHandler OnDropDownClosing;
