Do you mean sizing handles which appear only when working with the Designer?

Hello,

You will need to add a designer for your user control and use SelectionRules. (add a reference to System.Design.dll)

Public Overrides ReadOnly Property SelectionRules As SelectionRules
Get
    Return MyBase.SelectionRules And Not SelectionRules.AllSizeable
End Get
End Property

To add a designer add a designer attribute:

<designer(gettype(mydesigner))> _
Public Class MyUserControl
	Inherits System.Windows.Forms.UserControl

Then add a new designer class :

Imports System.Windows.Forms.Design

Public Class MyDesigner
	Inherits System.Windows.Forms.Design.ControlDesigner

    Public Overrides ReadOnly Property SelectionRules() As System.Windows.Forms.Design.SelectionRules
        Get
            Return MyBase.SelectionRules And Not SelectionRules.AllSizeable
        End Get
    End Property
End Class

That should do the trick... I am a C# developer excuse the VB.net errors :)

Hello,

It does work but probably I did not give enough details. :(

First make sure you target .Net4 not .Net4 client profile, go to project properties, Compile tab, Advanced Compile options, at the bottom select .Net 4 (not the default .Net4 client profile)

Second create your user control. (I called it UserControl1)

Third add a reference in you project to "System.Design.dll" (it is located in C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0 )

Fourth add a new class in your project, and use this code:

VB

Imports System.Windows.Forms.Design

Public Class UserControl1Designer
    Inherits System.Windows.Forms.Design.ControlDesigner

    Public Overrides ReadOnly Property SelectionRules() As System.Windows.Forms.Design.SelectionRules
        Get
            Return MyBase.SelectionRules And Not SelectionRules.AllSizeable
        End Get
    End Property
End Class

Fifth Open up the code of your user control (press F7 if you are in the designer)
make sure it looks like something like that:

VB

Imports System.ComponentModel

<designer(gettype(usercontrol1designer))>
Public Class UserControl1
    Inherits System.Windows.Forms.UserControl
End Class

Done.

Now when you will drag your usercontrol on a form you will notice that it is not resizable.

Valery.
