One button with 2 actions - winforms

Question

I did try to make 1 button that makes 2 actions: one on the 1st press (click), the other on the 2nd press (click), and repeat. However, none of my approaches worked for me, so I made 2nd button to make 2nd action, but I would really like to have only one. Here is small example that should help you help me :).
#This creates the all button and sets the event
$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Size(60,20)
$OKButton.Size = New-Object System.Drawing.Size(30,20)
$OKButton.Text = "all"
$OKButton.Add_Click({
$ua2Checkbox.Checked=$true;
$nvsCheckbox.Checked=$true;
$krsCheckbox.Checked=$true;
$uaCheckbox.Checked=$true;
$hbrCheckbox.Checked=$true;
})
$objForm.Controls.Add($OKButton)
$objForm.Add_Shown({$objForm.Activate()})
#This creates the none button and sets the event
$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Size(100,20)
$OKButton.Size = New-Object System.Drawing.Size(40,20)
$OKButton.Text = "None"
$OKButton.Add_Click({
$ua2Checkbox.Checked=$false;
$nvsCheckbox.Checked=$false;
$krsCheckbox.Checked=$false;
$uaCheckbox.Checked=$false;
$hbrCheckbox.Checked=$false;
})
$objForm.Controls.Add($OKButton)
$objForm.Add_Shown({$objForm.Activate()})
$actionAll = {
#$ua2Checkbox.Checked=$true;$nvsCheckbox.Checked=$true;$krsCheckbox.Checked=$true;$uaCheckbox.Checked=$true;$hbrCheckbox.Checked=$true;
#$OKButton.Add_Click($ua2Checkbox.Checked=$true;$nvsCheckbox.Checked=$true;$krsCheckbox.Checked=$true;$uaCheckbox.Checked=$true;$hbrCheckbox.Checked=$true;)
#$OKButton.Remove_click({$ua2Checkbox.Checked=$false;$nvsCheckbox.Checked=$false;$krsCheckbox.Checked=$false;$uaCheckbox.Checked=$false;$hbrCheckbox.Checked=$false;})
}
$actionnone = {
#$ua2Checkbox.Checked=$false;$nvsCheckbox.Checked=$false;$krsCheckbox.Checked=$false;$uaCheckbox.Checked=$false;$hbrCheckbox.Checked=$false;
#$OKButton.Add_Click($ua2Checkbox.Checked=$false;$nvsCheckbox.Checked=$false;$krsCheckbox.Checked=$false;$uaCheckbox.Checked=$false;$hbrCheckbox.Checked=$false;)
#$OKButton.Remove_click({$ua2Checkbox.Checked=$false;$nvsCheckbox.Checked=$false;$krsCheckbox.Checked=$false;$uaCheckbox.Checked=$false;$hbrCheckbox.Checked=$false;})
}
$OKButton.Location = New-Object System.Drawing.Size(60,20)
$OKButton.Size = New-Object System.Drawing.Size(30,20)
$OKButton.Text = "all"
$OKButton.Add_Click({invoke-expression "$actionAll"})
$OKButton.Remove_click({invoke-expression "$actionnone"})
#$OKButton.MouseDoubleClick({$ua2Checkbox.Checked=$false;$nvsCheckbox.Checked=$false;$krsCheckbox.Checked=$false;$uaCheckbox.Checked=$false;$hbrCheckbox.Checked=$false;})
$objForm.Controls.Add($OKButton)
$objForm.Add_Shown({$objForm.Activate()})

If you want to toggle the action of the button each time the button is clicked, you need to replace the current action with the other action within each action:
$actionAll = {
# other operations here
$OKButton.Text = 'None'
$OKButton.Remove_Click($actionAll)
$OKButton.Add_Click($actionNone)
}
$actionNone = {
# other operations here
$OKButton.Text = 'All'
$OKButton.Remove_Click($actionNone)
$OKButton.Add_Click($actionAll)
}
$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Text = 'All'
$OKButton.Add_Click($actionAll)
$objForm.Controls.Add($OKButton)
