如何灰显依赖于特定实例的C#窗体上的按钮

我有一个检查服务是否正在运行的方法，以及一个按钮，当单击该按钮时启动该方法。尽管如果服务没有安装，有没有办法"灰显"按钮？

public static void StopService(string serviceName, int timeoutMilliseconds)
{
    ServiceController service = new ServiceController(serviceName);
    try
    {
        TimeSpan timeout = TimeSpan.FromMilliseconds(timeoutMilliseconds);
        service.Stop();
        service.WaitForStatus(ServiceControllerStatus.Stopped, timeout);
        MessageBox.Show("The service was successfully turned on");
    }
    catch
    {
         MessageBox.Show("Service is not installed!");
    }
}
private void button14_Click_1(object sender, EventArgs e)
{
    StopService("Update Scheduler Service", 20000);
}
