在页面初始化时或查询数据时会比较慢，有没有办法加个等待页面上去？

[TLJewel]

如题。
我做的时wince开发，但是平常的winform解决办法也可以。

另开一个线程，就跟进度条一样

1.可以做一个等待的窗口，将窗口的ControlBox属性设为False，窗体中加个等待的GIF图片
2.之后可利用BackgroundWorker控件或者Thread来做等待效果

//BackgroundWorker控件，等待效果
private void DoSearch(object sender, EventArgs e)
{
    BackgroundWorker worker = GetWorker();
    worker.RunWorkerAsync();
    //Your Search function
    worker.CancelAsync();
}
private BackgroundWorker GetWorker()
{
    BackgroundWorker worker = new BackgroundWorker();
    worker.DoWork += new DoWorkEventHandler(worker_DoWork);
    worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(worker_RunWorkerCompleted);
    worker.WorkerSupportsCancellation = true;
    return worker;
}
private void worker_DoWork(object sender, DoWorkEventArgs e)
{
            MessageForm mf = new MessageForm();
            mf.Show();
            BackgroundWorker worker = (BackgroundWorker)sender;
            while (true)
            {
                mf.BringToFront();
                mf.Refresh();
                if (worker.CancellationPending)
                {
                    mf.Close();
                    e.Cancel = true;
                }
                else
                {
                    e.Cancel = false;
                }
                System.Threading.Thread.Sleep(10);
            }
}
private void worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
            if (e.Cancelled)
                ((BackgroundWorker)sender).Dispose();
}

ThreadPool.QueueUserWorkItem(delegate{异步执行的方法},要传入线程的参数);

异步执行的方法（object obj）
｛
 经过访问是数据库等操作以后，如果要更新UI界面 
就使用this.invoke(delegate{操作UI控件的方法}) 
｝

操作UI控件的方法（）
