这很容易找到，但我花了很多时间才找到这个过程。这就是我做的事情

我接受了这一行

$CB_Consultant.CheckState

并用以下代码替换它：

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

结果是一个带有两个灰色区域的复选框，当您单击复选框时，另外两个字段将变为活动状态。

           #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
           }  
           })

也许Windows Forms不是在PowerShell中执行此操作的最佳方式。你见过这个吗？

或者也许使用WPF来实际创建富客户端应用程序而不是PowerShell中的脚本。

Answer 4

如果您使用的是System.Windows.Forms复选框，则此方法有效，但如果您使用的是System.Windows.Controls复选框则不行，如果您在XAML中创建GUI，则会出现这种情况。< / p>

对于XAML，您需要添加单独的状态，如下例所示。在这个例子中，我们有一个名为tabcheckBox的复选框和一个名为TabVMBtnDeleteVM的按钮。选中此框后，该按钮将被禁用。取消选中该框后，该按钮即被启用。

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