MVVM WPF数据绑定到类似Skype的聊天？ [英] MVVM WPF databinding to a Skype-like chat?

问题描述

伙计们，我觉得这是一个有趣的问题：

你们都知道并喜欢Skype聊天界面：每个消息都封装在泡沫中，表情符号和链接功能，以及左侧的头像。

如果我正在创建一个类似Skype的界面，那么每个邮件的最理想的WPF组件是什么？

我正在使用MVVM，所以我的所有消息都作为ObservableCollection存储在ViewModel中。

我有有问题绑定到RichTextBox，所以我已经调查绑定到列表框，其中每个列表项是一个消息，每个项目被风格为具有Skypey边框和头像等。

任何想法？

解决方案

我发现唯一合适的解决方案是使用flowdocumentreader和ivalueconverter来转换数组的字符串到一个流文件。一旦我制作了类似于bbcode的脚本语言，它实际上会很好用。

这是我从中学到的示例。 http://michaelsync.net/2009/ 06/09 / bindable-wpf-richtext-editor-with-xamlhtml-convertor

对我来说有点过分，所以我最终只是做ivalueconverter和简单的脚本语言。

Hey guys, I've got what I think is an interesting question:

You all know and love the Skype chat interface: each message is enclosed in a bubble, with emoticons and link capabilities, as well as an avatar at the left.

What is the most ideal WPF component to house each message in, if I were creating a Skype-like interface?

I am using MVVM, so all my messages are stored in the ViewModel as an ObservableCollection.

I have had problems binding to a RichTextBox, and so I have investigated binding to a Listbox, where each list item is a message and each item is styled to have a Skypey border and avatar etc.

Any ideas?

解决方案

The only suitable solution that I have found is using the flowdocumentreader and an ivalueconverter to convert an array of strings to a flowdocument. It actually works great once I made my own scripting language similar to bbcode.

This was the sample I learned from. http://michaelsync.net/2009/06/09/bindable-wpf-richtext-editor-with-xamlhtml-convertor

It was a little overkill for me so I ended up just making the ivalueconverter and a simple script language.
