如何通过线程将节点添加到TreeView中？ [英] How to add nodes into TreeView via Threads?

问题描述

我是动态创建的TreeView，能够使用按钮更新/添加节点。

问题是，如果我是使用线程。


任何想法和建议？

Hi,

I am dynamically created TreeView and able to update/add nodes using button.
The problem is nothing is being done if I was using threads.

Any ideas and suggestion?

推荐答案

请记住，您不应该访问UI线程直接。你将需要在UI线程中创建一个AddNode方法，然后从你的线程中调用

Remember that you should not access data on the UI thread directly. You''ll
need to create an AddNode method in the UI thread and then invoke that from
your thread.

我实际上使用类似的方法PictureBox的工作原理......


听起来像唯一的方法就是UI中的AddNote？但问题是我只收到线程上的

数据，然后我知道要添加到TreeView中的内容。


希望我的解释清楚明了...

I actually use similar method of PictureBox and it works...

Sound like the only way is the AddNote in UI? But problem I only receive the
data on threads, then I know what to be added into the TreeView.

Hope my explanaition is clear enought...

记住你不应该直接访问UI线程上的数据。你需要在UI线程中创建一个AddNode方法，然后从你的线程中调用它。

这并不意味着它应该工作，它总会有效，甚至可以在所有情况下都能正常工作。

听起来像唯一的方法是UI中的AddNote？但问题是我只收到线程上的数据，然后我知道要添加到TreeView中的内容。

希望我的解释很清楚......

I actually use similar method of PictureBox and it works...
That doesn''t mean it should work, that it will always work, or even
that it currently works in all situations.
Sound like the only way is the AddNote in UI? But problem I only receive the
data on threads, then I know what to be added into the TreeView.

Hope my explanaition is clear enought...
