[RESOLVED] How can I detect when ParentForm's properties are changing?

[Simonetos The Greek]

Greetings to everyone!!!


I am working on a couple of UserControls lately and this time is a custom TitleBar. What I want to do is to detect when ParentForm's properties (like ControlBox for example) is changing by developer in Design Time and then update my TitleBar.

So I added a Timer into my UserControl to do this "work". It works, but I think this isn't the most appropriate approach...

Private Sub Timer_Tick(sender As Object, e As EventArgs) Handles Timer.Tick     Me.ControlBox = Me.ParentForm.ControlBox
    If ParentForm.ControlBox = True Then ControlsBox_FlowLayoutPanel.Visible = True Else ControlsBox_FlowLayoutPanel.Visible = False
    If ParentForm.MinimizeBox = True Then MinimizeButton_PictureBox.Visible = True Else MinimizeButton_PictureBox.Visible = False
    Me.MinimizeBox = Me.ParentForm.MinimizeBox
    If ParentForm.MaximizeBox = True Then MaximizeButton_PictureBox.Visible = True Else MaximizeButton_PictureBox.Visible = False
    Me.MaximizeBox = Me.ParentForm.MaximizeBox
End Sub

Is there any other way to do that and not by using a Timer? For example, to detect ParentForm's Text property and then update my UserControl's Text, I do something like this...

Private WithEvents _ParentForm As Form
 
Protected Overrides Sub OnParentChanged(e As EventArgs)
    MyBase.OnParentChanged(e)
    _ParentForm = Me.ParentForm
    Call ParentForm_TextChanged()
End Sub
 
Private Sub ParentForm_TextChanged() Handles _ParentForm.TextChanged
    If _ParentForm Is Nothing Then
        FormTitle_Label.Text = FormTitle_Label.Text
    Else
        FormTitle_Label.Text = _ParentForm.Text
    End If
    Invalidate()
End Sub

Is there anything similar for properties like ControlBox, MinimizeBox and MaximizeBox?

Thank you in advance!!!
