Need assist with add_click no passing 1+ parameter

So I have an XAML interface and I am trying to uncheck a box and change its foreground color from one color to another. Unfortunately, it is not working as planned. Even though I have both commands running within the Add_Click event, I have to click twice, one-click to uncheck, and then another click to change its color, but it's not working as a whole. I've even tried running it from a function and it's still a recurring issue.

What I have tried:

When checked if $DC shows a lock

PowerShell

If($UserInfo.LastBadPasswordAttempt){
    if($UserInfo.LockedOut -eq $true) {
        if($DC -match $_chkServer1.Content) {
            $_chkServer1.IsChecked = $true
            $_chkServer1.Foreground = 'Red'
        }
    }        
}

Then when users uncheck with the Add_Click({}) event.

PowerShell

$_chkServer1.Add_Click({
    if($_chkServer1.IsChecked)
    {
        $_chkServer1.IsChecked = $false             
        $_chkServer1.Foreground = 'Green'
    }
})

And then with a function

PowerShell

$_chkServer1.Add_Click({
    if($_chkServer1.IsChecked)
    {
        ChangeState -i 1
    }
}) 

Function ChangeState([int]$i)
{
    switch ($i)
    {
        1 {
            $_chkServer1.IsChecked = $false             
            $_chkServer1.Foreground 
        }
    }
}

The foreground does not change with the uncheck. When I uncheck, the foreground remains the same (red) then I click again (on the content of the checkbox), then it changes to green. What the result should be: When I uncheck the box, it should automatically switch green, but it does not do this, I have the click it twice for it to turn green.

If the box is checked and the user clicks on it, it will be unchecked before the Click event is raised.

So the first time you click, the box is unchecked, and your event handler does nothing. The second time you click, the box is checked, and your event handler unchecks it again.

Change your event handler to:

PowerShell

$_chkServer1.Add_Click({
    if (-Not $_chkServer1.IsChecked)
    {
        $_chkServer1.Foreground = 'Green'
    }
})
