How to organize a cycle of disabling comboboxes from dynamically formed combobox name elements?

Source code without optimization

function ClearOuList($count)
{
  #$comboboxOuNext1.DataSource = $null
  switch ($count) {
    1 {
      $comboboxOuNext1.visible = $false
      $comboboxOuNext2.visible = $false
      $comboboxOuNext3.visible = $false
      $comboboxOuNext4.visible = $false
      $comboboxOuNext5.visible = $false
      $comboboxOuNext6.visible = $false
      $comboboxOuNext7.visible = $false
      $comboboxOuNext8.visible = $false
      $comboboxOuNext9.visible = $false
      $comboboxOuNext10.visible = $false
    }
    2 {
      $comboboxOuNext2.visible = $false
      $comboboxOuNext3.visible = $false
      $comboboxOuNext4.visible = $false
      $comboboxOuNext5.visible = $false
      $comboboxOuNext6.visible = $false
      $comboboxOuNext7.visible = $false
      $comboboxOuNext8.visible = $false
      $comboboxOuNext9.visible = $false
      $comboboxOuNext10.visible = $false
    }
    3 {
      $comboboxOuNext3.visible = $false
      $comboboxOuNext4.visible = $false
      $comboboxOuNext5.visible = $false
      $comboboxOuNext6.visible = $false
      $comboboxOuNext7.visible = $false
      $comboboxOuNext8.visible = $false
      $comboboxOuNext9.visible = $false
      $comboboxOuNext10.visible = $false
    }
    4 {
      $comboboxOuNext4.visible = $false
      $comboboxOuNext5.visible = $false
      $comboboxOuNext6.visible = $false
      $comboboxOuNext7.visible = $false
      $comboboxOuNext8.visible = $false
      $comboboxOuNext9.visible = $false
      $comboboxOuNext10.visible = $false
    }
    5 {
      $comboboxOuNext5.visible = $false
      $comboboxOuNext6.visible = $false
      $comboboxOuNext7.visible = $false
      $comboboxOuNext8.visible = $false
      $comboboxOuNext9.visible = $false
      $comboboxOuNext10.visible = $false
    }
    6 {
      $comboboxOuNext6.visible = $false
      $comboboxOuNext7.visible = $false
      $comboboxOuNext8.visible = $false
      $comboboxOuNext9.visible = $false
      $comboboxOuNext10.visible = $false
    }
    7 {
      $comboboxOuNext7.visible = $false
      $comboboxOuNext8.visible = $false
      $comboboxOuNext9.visible = $false
      $comboboxOuNext10.visible = $false
    }
    8 {
      $comboboxOuNext8.visible = $false
      $comboboxOuNext9.visible = $false
      $comboboxOuNext10.visible = $false
    }
    9 {
      $comboboxOuNext9.visible = $false
      $comboboxOuNext10.visible = $false
    }
    10 {
      $comboboxOuNext10.visible = $false
    }
  }

The misunderstanding lies in the formation of the name of the combobox in a loop for its subsequent disabling. If you form a dynamic name in a cycle, from the part of the name of the necessary variable + cycle variable (for example: $comboboxOuNext$i, where $i=8), then you lose control over the real name of the combobox, since the compound variable is already a string variable and it has there are no properties of type visible, e.g. Such a variable is not a reference to the required combobox object and is not its real name, although visually and identically. If you create a variable of the combobox type, then this construction still does not work, since it turns out that this, apparently, is another intra-procedural object ... Maybe there are some pointers to the necessary objects that can be dynamically formed in cycles and which will be correctly on them indicate?

Try like this:

function ClearOuList($count)
{
  #$comboboxOuNext1.DataSource = $null
  switch ($count) {
    1 {
         Get-Variable -Name "comboboxOuNext[1-9]" | %{$_.Value.visible=$false
         Get-Variable -Name "comboboxOuNext10" | %{$_.Value.visible=$false
        }
    2 {
         Get-Variable -Name "comboboxOuNext[2-9]" | %{$_.Value.visible=$false
         Get-Variable -Name "comboboxOuNext10" | %{$_.Value.visible=$false
        }
    3 {
         Get-Variable -Name "comboboxOuNext[3-9]" | %{$_.Value.visible=$false
         Get-Variable -Name "comboboxOuNext10" | %{$_.Value.visible=$false
        }
    4 {
         Get-Variable -Name "comboboxOuNext[4-9]" | %{$_.Value.visible=$false
         Get-Variable -Name "comboboxOuNext10" | %{$_.Value.visible=$false
        }
    5{
         Get-Variable -Name "comboboxOuNext[5-9]" | %{$_.Value.visible=$false
         Get-Variable -Name "comboboxOuNext10" | %{$_.Value.visible=$false
        }
    6{
         Get-Variable -Name "comboboxOuNext[6-9]" | %{$_.Value.visible=$false
         Get-Variable -Name "comboboxOuNext10" | %{$_.Value.visible=$false
        }
    7 {
         Get-Variable -Name "comboboxOuNext[7-9]" | %{$_.Value.visible=$false
         Get-Variable -Name "comboboxOuNext10" | %{$_.Value.visible=$false
        }
    8 {
         Get-Variable -Name "comboboxOuNext[89]" | %{$_.Value.visible=$false
         Get-Variable -Name "comboboxOuNext10" | %{$_.Value.visible=$false
        }
    9 {
         Get-Variable -Name "comboboxOuNext9" | %{$_.Value.visible=$false
         Get-Variable -Name "comboboxOuNext10" | %{$_.Value.visible=$false
        }
    10 {
          Get-Variable -Name "comboboxOuNext10" | %{$_.Value.visible=$false
        }
  }
}

}
You can also consider quantifiers:

Get-Variable * | ? {$_.name -match "comboboxOuNext[0-9]{1,2}"}
