Why use the CheckedChanged event?

Use the CheckedChanged event when you wish to respond to when a user changes the check box state by modifying the form controls or running a script . For example, you may wish to disable certain controls depending on the checkbox’s current value.

In this example,  the event script disables the input textboxes for UserName and Password when the “Use Alternate Credentials” checkbox is unchecked.

$checkboxUseAltCred_CheckedChanged={
    #Enable or Disable the TextBox controls
    $textboxUserName.Enabled = $checkboxUseAltCred.Checked
    $textboxPassword.Enabled = $checkboxUseAltCred.Checked
}

When the checkbox is unchecked, the textboxes are disabled:

OnCheckedChanged Unchecked

When the checkbox is checked, the textboxes are enabled:

OnCheckedChanged Checked
