Brilliant!! Thank you sooo much!!!! &nbsp;I removed the second add and inserted the one line into the move event and it works 
like a charm!! &nbsp;I just would have expected since the parents of all relevant controls were being set, that moving the container 
for all those contained controls would move with it? &nbsp; &nbsp;Again, thanks a bunch!!!

&quot;I just would have expected since the parents of all relevant controls were being set, that moving the container 
for all those contained controls would move with it?&quot; 
 
Once you add those controls to the PictureBox (or Form) the Parent is no longer your custom Panel so moving the Panel will have no effect on those controls. 
 
In this case, the &quot;Parent&quot; is the Control that is visually containing the controls...not the class that holds the reference. 
 
Hope that makes sense...

I'm sorry to be a pest, but I thought I had all the problems sorted out but it appears as though that panel1 gets left behind when using the mouse 
to move it instead of the button. 
 
Further, compare the way the snapping of the moveable panel is before hitting the move button (cursor starts at upper left of the panel when 
dragging) and after (cursor starts in the middle of the panel when dragging it), the panel snaps to a different part on drag of the panel to some 
other location on the picturebox. &nbsp;This out distance gets worse the more the panel move until eventually the cusror is dragging the panel but the 
panel does not appear on top of the panel! &nbsp;I just take a read of the current x&amp;y of the mouse cursor and feed that in to a new point. &nbsp;Why is it 
not snapping the mouse cursor to the same point on the panel all the time? &nbsp;Ideally, it would not snap the panel to the cursor at all but move it 
using the point wherever it is on the top label of the control. 

</div>

<div>
wow. &nbsp;One sentence in that last paragraph didn't come our as intended! &nbsp;What I meant to say was that the more the panel is moved across the form, the worse the 
distance between the current cursor position and the panel itself gets (when mouse dragging the panel) until, eventually, the cursor no longer appears to be on top of the panel.

Sorry...I hadn't even tried moving it with the mouse. &nbsp;I'll take a look.

In your Load() event of ListBoxExt, add a line to also wire up the MouseDown() event of Label1: 
 
&nbsp; &nbsp; &nbsp; &nbsp; AddHandler Panel1.Scroll, AddressOf Panel1_Scroll 
&nbsp; &nbsp; &nbsp; &nbsp; AddHandler Label1.MouseMove, AddressOf Panel1_MouseMove 
 &nbsp; &nbsp; &nbsp; &nbsp;AddHandler Label1.MouseDown, AddressOf Panel1_MouseDown ' &lt;-- Also Handle the MouseDown() Event 
&nbsp; &nbsp; &nbsp; &nbsp; AddHandler Panel1.Resize, AddressOf Panel1_Resize 
 
Now, add a variable to hold the position when the mouse is pressed down: 
 
&nbsp; &nbsp; Private pt As Point 
 
Finally, the MouseDown() and MouseMove() should look like: 
 
&nbsp; &nbsp; Private Sub Panel1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) 
&nbsp; &nbsp; &nbsp; &nbsp; If e.Button = Windows.Forms.MouseButtons.Left Then 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; pt = New Point(e.X, e.Y) 
&nbsp; &nbsp; &nbsp; &nbsp; End If 
&nbsp; &nbsp; End Sub 
 
&nbsp; &nbsp; Private Sub Panel1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) 
&nbsp; &nbsp; &nbsp; &nbsp; If m_Moveable = True AndAlso e.Button = Windows.Forms.MouseButtons.Left Then 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Panel1.Location = New Point(Panel1.Location.X + (e.X - pt.X), Panel1.Location.Y + (e.Y - pt.Y)) 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Me.Location = Panel1.Location 
&nbsp; &nbsp; &nbsp; &nbsp; End If 
&nbsp; &nbsp; End Sub 
 
All, together, that would be: 

<pre><code class="code-10 nolinks" id="code-8225431">Public Sub Load(ByVal frmReference As Form, ByVal Pichost As PictureBox)
 m_frmReference = frmReference
 m_PicHost = Pichost
 Panel1 = New Panel
 Panel2 = New Panel
 Label1 = New Label

 Pichost.Controls.Add(Panel1)
 Panel1.Controls.Add(Label1)
 Panel1.Controls.Add(Panel2)

 Panel2.Top = Label1.Height

 Label1.BackColor = Color.FromArgb(150, 0, 0, 102)
 Label1.Parent = Panel1
 Label1.AutoSize = False
 Label1.Dock = DockStyle.Top
 Label1.ForeColor = Color.White
 Label1.TextAlign = ContentAlignment.MiddleCenter

 Label1.AllowDrop = True
 Panel2.AllowDrop = True

 Dim myFont As New Font(&quot;Verdana&quot;, 10, FontStyle.Bold)
 Label1.Font = myFont

 Me.Parent = Pichost
 Me.BackColor = Color.Transparent
 Panel1.BackColor = Color.Transparent
 Panel1.Parent = Pichost
 Panel2.Parent = Panel1
 Panel2.Anchor = AnchorStyles.Left + AnchorStyles.Right + AnchorStyles.Top + AnchorStyles.Bottom
 myControlArray = New LabelArray(Panel2)
 Panel2.BackColor = Color.FromArgb(150, 190, 190, 190)
 Panel2.AutoScroll = True

 Panel1.BringToFront()

 AddHandler Panel1.Scroll, AddressOf Panel1_Scroll
 AddHandler Label1.MouseMove, AddressOf Panel1_MouseMove
 AddHandler Label1.MouseDown, AddressOf Panel1_MouseDown ' &lt;-- Also Handle the MouseDown() Event
 AddHandler Panel1.Resize, AddressOf Panel1_Resize

 AddHandler Panel2.DragDrop, AddressOf Panel2_DragDrop
 AddHandler Panel2.DragOver, AddressOf Panel2_DragOver

 SetStyle(ControlStyles.AllPaintingInWmPaint Or _
 ControlStyles.DoubleBuffer Or _
 ControlStyles.ResizeRedraw Or _
 ControlStyles.UserPaint, _
 True)
 End Sub

 Private pt As Point

 Private Sub Panel1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)
 If e.Button = Windows.Forms.MouseButtons.Left Then
 pt = New Point(e.X, e.Y)
 End If
 End Sub

 Private Sub Panel1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)
 If m_Moveable = True AndAlso e.Button = Windows.Forms.MouseButtons.Left Then
 Panel1.Location = New Point(Panel1.Location.X + (e.X - pt.X), Panel1.Location.Y + (e.Y - pt.Y))
 Me.Location = Panel1.Location
 End If

Hi Experts, 
 
I am stumped. &nbsp;I cannot seem to move my custom &quot;control&quot; programmatically (just a class inheriting from a control class really) when I set the parent to a picturebox. &nbsp;I do this because I need to be able to have the controls background to be translucent or see-through in varying degrees. &nbsp;Sample app code is attached. &nbsp;Perhaps it is something simple but I have looked at it up, down, sideways, and backwards, and can't seem to make it do what I want which is to simply move the whole control programmatically through code. &nbsp;Currently, only one of the elements contained in the &quot;control&quot; gets moved and not anything else. &nbsp;I also tried putting it into a custom usercontrol figuring I'd see a difference but had the same results. &nbsp;Sample is attached. 
 
TIA

Hi Experts, 

I am stumped.  I cannot seem to move my custom "control" programmatically (just a class inheriting from a control class really) when I set the parent to a picturebox.  I do this because I need to be able to have the controls background to be translucent or see-through in varying degrees.  Sample app code is attached.  Perhaps it is something simple but I have looked at it up, down, sideways, and backwards, and can't seem to make it do what I want which is to simply move the whole control programmatically through code.  Currently, only one of the elements contained in the "control" gets moved and not anything else.  I also tried putting it into a custom usercontrol figuring I'd see a difference but had the same results.  Sample is attached.

TIA
 

Can't seem to programmatically move a custom &quot;control&quot; when parent is set to a picturebox

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,
