在另一个线程中动态地将控件添加到 WinForms [英] Add Controls to WinForms dynamically in another Thread

问题描述

我有一个包含数据网格视图、绑定源、文件资源管理器控件等的 Winform...

I have a Winform that contains a datagridview, bindingsource, file explorer control, etc...

我需要动态地向面板添加几个控件(自定义用户控件)(如 Panel.Controls.Add(...)).这个过程可能很慢.

I need add several controls (Custom UserControls) to a Panel dynamically (like Panel.Controls.Add(...)). This process can be slow.

我想向用户显示一条消息(等待).

I want to show to the user a message (waiting).

最好的方法是什么?我使用 Backgroundworker，但我遇到了问题，我的应用程序没有响应，datagridview 没有显示垂直滚动条，还有一些奇怪的事情.

What is the best way? I use Backgroundworker but I have problems, my application not responds and datagridview not shows scrollbar vertical, and another strange things.

推荐答案

线程可能不是此类 gui 操作的最佳选择.所有控件都应该在同一个线程上创建.

A thread is probably not your best bet for gui operations like this. All controls should be created on the same thread.

而是在表单底部放置一个状态栏控件.在状态栏上，包括一个进度条和一个标签.添加控件时，通过在标签中包含一条消息并增加进度条，在状态栏上指明这一点.

Instead put a statusbar control at the bottom of your form. On the statusbar, include a progress bar and a label. When adding a control, indicate this on the statusbar by including a message in the label and incrementing the progressbar.
