WPF listview对动态数据进行分组 [英] WPF listview grouping on dynamic data

问题描述

我有一个动态填充的列表视图，我根据他们的MD5校验和对项目进行分组。一切都很好，但我希望将这些MD5代码转换为数字。我的意思是组应显示标题组1，组2等。
组名称数等于唯一MD5值的数量。对静态数据进行分组非常简单，因为数字已知。到目前为止，我还没弄清楚如何为动态数据做这件事。

解决方案

嗨Waleed，

根据你的描述，你想将MD5代码转换成一个数字，我建议你用IValueConverter来做这个，有一个关于如何使用Ivalueconverter的文档，你可以看看：

您可以根据需要修改代码。

最诚挚的问候，

I have a listview which is populated dynamically, I am grouping items based on their MD5 checksum. Its all good but I would like those MD5 codes to be converted to a number. What I mean is Groups should be displayed with headings Group 1, Group 2 etc. Number of Group names is equal to the number of unique MD5 values. Grouping on static data is extremely simple as the number is already known. I havent been able to figure out how to do it for dynamic data till now.

解决方案

Hi Waleed,

According to your description, you want to converter MD5 code to a number, I suggest you use IValueConverter to do this, there is a document on how to use Ivalueconverter, you can take a look:

You can modify the code according to your needs.
