$OnLoadForm_StateCorrection=
{#Correct the initial state of the form to prevent the .Net maximized form issue
    $Form_UC_Main.WindowState = $InitialFormWindowState
}

Answer 1

It was so easy to find, but it took me so many time to find that process. Here's what I did

I took this line

$CB_Consultant.CheckState

and replace it by this code :

$CB_Consultant.Add_CheckStateChanged({
    $TB_Company.enabled = $CB_Consultant.Checked
    $CB_EndDate.enabled = $CB_Consultant.Checked
    #and so on
})

The Result is a checkbox with two grayout field, when you click the Checkbox, the two other field turn to active state.

This approach works if you're using a System.Windows.Forms Checkbox, but not if you're using a System.Windows.Controls checkbox, which is what you'll have if you make your GUI in XAML.

For XAML, you'll need to add separate states, as seen in the below example. In this example, we have a checkbox named tabcheckBox and a button named TabVMBtnDeleteVM. When the box is checked, the button is disabled. When the box is unchecked, the button is enabled.

$tabcheckBox.Add_Checked({$TabVMbtnDeleteVM.IsEnabled = $false})
$tabcheckBox.Add_Unchecked({$TabVMbtnDeleteVM.IsEnabled = $true})

Answer 3

#Add below code after the checkBox code which you are created.
$CB_Consultant.Add_CheckStateChanged({
     if($CB_Consultant.checked){
          $CB_EndDate.enabled = $CB_Consultant.checked
          $TB_Company.enabled = $CB_Consultant.checked
     } else {
          $CB_EndDate.enabled = $CB_Consultant.checked
          $TB_Company.enabled = $CB_Consultant.checked
    }  
})

Perhaps Windows Forms is not the best way to do this in powershell. Have you seen this?

Or maybe use WPF to actually create a rich client app instead of scripting in powershell.
