How to display a floating control when the HostForm is minimized?

Platform: WinForms |
Control: DockingManager |

We can display a floating control when the HostForm is minimized by setting the FloatingForm''s visible property to true in the Form_Layout event.

C#

private void Form1_Layout(object sender, LayoutEventArgs e)

{

if (this.WindowState == FormWindowState.Minimized)

{

if (dockingManager1.IsFloating(panel1))

{

FloatingForm ff = panel1.Parent.Parent as FloatingForm;

ff.WindowState = FormWindowState.Normal;

ff.Visible = true;

}

}

}

VB

Private Sub Form1_Layout(ByVal sender As Object, ByVal e As LayoutEventArgs) Handles MyBase.Layout

If Me.WindowState = FormWindowState.Minimized Then

If dockingManager1.IsFloating(panel1) Then

Dim ff As FloatingForm = TryCast(panel1.Parent.Parent, FloatingForm)

ff.WindowState = FormWindowState.Normal

ff.Visible = True

End If

End If

End Sub
