Custom ListView not highlighting ListViewItem on click

阅读更多关于 Custom ListView not highlighting ListViewItem on click

I have a custom listview made up of an ImageView and a TextView. Clicking works fine however it won't highlight the item like a normal ListView would. How would I add a highlight? I tried to rig it by setting the background color on click and then adding a timer to remove the background color. That worked but I want a better solution. Any ideas?

WPF ListViewItem lost focus event - How to get at the event?

阅读更多关于 WPF ListViewItem lost focus event - How to get at the event?

I have a listview that you select a row/item on. This is linked to a datatrigger that displays an image on the row. The image should only be displayed when the row is selected. This part works fine, however when you move the focus to something else, such as a textbox, or a messagebox is displayed, the listviewitem loses focus ie the highlight on the row is no longer displayed. The problem is that my image still remains. It should be hidden/collapsed when the listview loses focus... It works fine if you select a different item/row on the listview. Can anyone help on this please? <Style x:Key=
