问题描述
我想通过TextBox的输入过滤ListView。根据场景，我的ListView被分成几组，一旦我清除ListView的Items集合以准备加载已过滤的列表 - 不是ListView的组，而是每个ListViewItem的组分配，我将失去这些组。
即使在调用Clear（）函数后，有没有办法在ListViewItems中保留该信息？
I want to filter a ListView going by a TextBox's input. Depending on the scenario, my ListView is divided into groups, which I lose once I Clear out the ListView's Items collection in preparation of loading the filtered list - not the ListView's Groups, but the Group allocation for each ListViewItem.
Is there any way to preserve that information in the ListViewItems even after calling the Clear() function?
