Question Get rid of designer resize handles

[Pirahnaplant]

How can I make my UserControl not have the resizing handles when placed on a form in design mode; similar to a label or a textbox?

This is how the ControlDesigner for Label does it:

Friend Class LabelDesigner
    Inherits ControlDesigner
    ' Methods
    Public Sub New()
        MyBase.AutoResizeHandles = True
    End Sub
 
    ' Properties
    Public Overrides ReadOnly Property SelectionRules() As SelectionRules
        Get
            Dim _selectionRules As SelectionRules = MyBase.SelectionRules
            Dim component As Object = MyBase.Component
            Dim descriptor As PropertyDescriptor = TypeDescriptor.GetProperties(component).Item("AutoSize")
            If ((Not descriptor Is Nothing) AndAlso CBool(descriptor.GetValue(component))) Then
                _selectionRules = (_selectionRules And Not SelectionRules.AllSizeable)
            End If
            Return _selectionRules
        End Get
    End Property

End Class

'(the code for text alignment snaplines was removed)

To define this Designer for your control:

Imports System.Windows.Forms.Design
Imports System.ComponentModel

<Designer(GetType(LabelDesigner))> _
 Public Class UserControl1

Requires reference to System.Design.

With this configured resize handles depends on the AutoSize property.
