ToolStripCheckBox

[JuggaloBrotha]

I've recently wanted a CheckBox in a ToolStrip and while that control doesn't exist in the framework, I did some googling and made my own:

Imports System.Windows.Forms.Design

<ToolStripItemDesignerAvailability(ToolStripItemDesignerAvailability.ToolStrip), DebuggerStepThrough()> _
Public Class ToolStripCheckBox
    Inherits ToolStripControlHost

    Public Sub New()
        MyBase.New(New System.Windows.Forms.CheckBox())
        ToolStripCheckBoxControl.BackColor = Color.Transparent
    End Sub

    Public ReadOnly Property ToolStripCheckBoxControl() As CheckBox
        Get
            Return TryCast(Control, CheckBox)
        End Get
    End Property

    Public Property ToolStripCheckBoxEnabled() As Boolean
        Get
            Return ToolStripCheckBoxControl.Enabled
        End Get
        Set(ByVal value As Boolean)
            ToolStripCheckBoxControl.Enabled = value
        End Set
    End Property

    Public Property Checked() As Boolean
        Get
            Return ToolStripCheckBoxControl.Checked
        End Get
        Set(ByVal value As Boolean)
            ToolStripCheckBoxControl.Checked = value
        End Set
    End Property

    Protected Overrides Sub OnSubscribeControlEvents(ByVal c As Control)
        MyBase.OnSubscribeControlEvents(c)
        AddHandler DirectCast(c, CheckBox).CheckedChanged, AddressOf OnCheckedChanged
    End Sub

    Protected Overrides Sub OnUnsubscribeControlEvents(ByVal c As Control)
        MyBase.OnUnsubscribeControlEvents(c)
        RemoveHandler DirectCast(c, CheckBox).CheckedChanged, AddressOf OnCheckedChanged
    End Sub

    Public Event CheckedChanged As EventHandler

    Private Sub OnCheckedChanged(ByVal sender As Object, ByVal e As EventArgs)
        RaiseEvent CheckedChanged(Me, e)
    End Sub
End Class

Just add that code to your project , build it then simply click the AddItem DropDown arrow on a ToolStrip and at the bottom, there it is.

Here's a screenshot of it being used:


I've also included a class file as well as an example project for this.

Nice! I'm going to test it out as soon as I get a chance. This definitely seems useful

I modified the code so the internal checkbox's backcolor is transparent, allows the toolstrip's gradient backcolor to show through the text

I am messing with a control like this for the first time. This code provided where would you put this? In a new Class or an existing class?

It's a control. So you can either create a control and paste in this code or just create a new class.

If you look at the code, it's a class. So you can't really put it in another class:

Public Class ToolStripCheckBox

Yea i knew it was a coded as a class. I guess my issue is once i add it to a new class I cannot figure out how to get it into my ToolStrip.

I read about adding it to the construct of the toolstrip, but I have never done this before. I go into the Designer of the Form but it throughs any when attempting this. Sorry I have dome a lot of things with code before just never tried building a control like this before.

The point I was making was that you can't put a class in a class.

There's nothing you need to do. Create the class, build the project, add the toolstrip to the form, and add the checkbox like you would any other native child control.

This is the error i get

Constructor on type 'System.Windows.Forms.ToolStripControlHost' not found.

C'mon, man. You're not even trying. I'm not going to do this for you. Hover over the error.

Actually you can:

Public Class OutterClass
 
  Private m_InnerClass As InnerClass
 
  Public Sub New()
    m_InnerClass = New InnerClass
  End Sub
 
  Private Class InnerClass
    Public Sub New()
    End Sub
  End Clas
 
End Class

This is the error i get

Constructor on type 'System.Windows.Forms.ToolStripControlHost' not found.

See post #1, I've included an example project, the control as a class file & a screenshot for ya.

Public Class OutterClass
 
  Private m_InnerClass As InnerClass
 
  Public Sub New()
    m_InnerClass = New InnerClass
  End Sub
 
  Private Class InnerClass
    Public Sub New()
    End Sub
  End Clas
 
End Class

Yeah. I don't know what I was thinking. I have classes within classes on several of my projects.

Maybe the context of the control confused me.
