RibbonGallery选中的项目被卡住了

问题描述

嗨！
$


在RibbonSplitButton中我有一个 RibbonGallery ，它有一个可观察集合的ItemsSource。

当点击下拉列表列表中的任何项目时，它会触发一个窗口显示。

问题是，当我关闭窗口时，打开再次下拉，之前选择的项目一直被选中，使我无法通过点击它触发窗口外观。



如果我更新observablecollection，下拉列表会更新，并且删除选择，但效率非常低。

如何删除选择以不同的方式？



提前致谢！

Hi!

Inside a RibbonSplitButton I have a RibbonGallery, which has an ItemsSource of an observablecollection.
When any item on the dropdown list is clicked, it triggers a window to be displayed.
The problem is, when I close the window, and open the dropdown again, the previously selected item keeps being selected, making it unable for me to trigger the windows appearence by clicking on it.

If I update the observablecollection, the dropdown is updated, and the selection is removed, but its pretty inefficient.

Any ideas how to remove the selection in a different fashion?

Thanks in advance!
