WPF - Extend ListView with checkable AND selectable ListViewItems
- by Marks
Hi there.
I already read many examples on extending ListViews with checkboxes bound with IsSelected. But I want something more.
I want a seperation between the checked and selected state, so i get a ListBox that has a single selected item, but can have multiple checked items.
Unfortunately ListViewItem does not have a property for checked and I dont see a possibility to get the ListView to work with a custom CheckableListViewItem.
Of course i could use a List of objects with a checked property as ItemSource, but I dont think thats a good way to go. Checked or not is a matter of the list or item-container, not of the object listed in it. Beside that I dont want all my classes like user, role, group to have counterparts like checkableUser, checkableRole and checkableGroup.
The behaviour i want can be easyly accomblished for the UI with a
<DataTemplate x:Key="CheckBoxCell">
<StackPanel Orientation="Horizontal">
<CheckBox />
</StackPanel>
</DataTemplate>
and a
<GridViewColumn CellTemplate="{StaticResource CheckBoxCell}" Width="30"/>
But without a binding on the checkbox i cant check if it is checked or not.
Is there any way to accomplish something like that? The perfect solution for me would be to have listView1.SelectedItem, listView1.CheckedItems and maybe a listView1.UncheckedItems and of course listView1.CheckItem and listView1.UncheckItem.
Thanks for any help.
