'Select Case' in vb.net

I have the following script which is using 'Select Case':

        Dim ctl As ToolStripButton = CType(sender, ToolStripButton)
        Dim MoveUp As Boolean = False
        Dim thisLV As ListView = AccountsLV

        Select Case ctl.Name
            Case "UpBtn1"
                MoveUp = True
                thisLV = ListView1
            Case "DownBtn1"
                MoveUp = False
                thisLV = ListView1
            Case "UpBtn2"
                MoveUp = True
                thisLV = ListView2
            Case "DownBtn2"
                MoveUp = False
                thisLV = ListView2
            Case "UpBtn3"
                MoveUp = True
                thisLV = ListView3
            Case "DownBtn3"
                MoveUp = False
                thisLV = ListView3
        End Select

As you can see, if the Name of the ToolStripButton begins with "Up", then I want 'MoveUp = True'. If not, then I want 'MoveUp = False'. Then, I want the number at the end of the toolstripbutton name to correspond with the ListView (i.e. DownBtn1 => 'thisLV = ListView1' or UpBtn3 => 'thisLV = ListView3')

Is there anyway to condense this? I am planning on having over 20 cases like this and don't want the code to get to lengthy.

if ctl.Name.Substring(0, 2).ToUpper.Equals("UP") then
MoveUp = True
else
MoveUp = False
end if

To shorten the 'thisLV', you could take off the last number and use a select case with that.

Can you explain the logic of:

Dim thisLV As ListView = Me.Controls.Find("ListView" & ctl.Name.Substring(ctl.Name.IndexOf("Btn") + 3), True)(0)

If you could explain it, then I might be able to use it in other instances
