C# - WPF ListView Confusing The SelectedItem With Equal Items
Jun 10, 2011A ListView (or ListBox) with following properties:
<ListView SelectionMode="Single">
<sys:String>James</sys:String>
<sys:String>Claude</sys:String>
[Code]....
will result in selecting two items simultaneously if I click on "James", even though I chose SelectionMode="Single". It's even the same behaviour when I use a helper class with a string-property to display in the ListView. It seems like the ListView is evaluating the Items and selecting those which are Equal() rather than ReferenceEqual(). Is there a way to change this behaviour so that the ListView treats every item individually?

Set Listview Items Name?
Jan 26, 2010If I look at all the options for
me.ListView1.Items(index)
one of them is for Name.
So instead of coding
Me.ListView1.Items(index)
I can use
Me.ListView1.Items("Name")
But if I go into the properties of the ListView1 and look at the collection for the Items there is no place to set the Name.I can code Me.ListView1.Items(1).Name = "Name" and then I can code Me.ListView1.Items("Name")Where can you set the "Name" of the Items in a ListView?

View 3 RepliesC# - Get ListView Visible Items?
Jun 25, 2012I have a ListView which might contains a lot of items, so it is virtualized and recycling items. It does not use sort. I need to refresh some value display, but when there are too many items, it is too slow to update everything, so I would like to refresh only the visible items.How could I get a list of all currently displayed items ? I tried to look into the ListView or in the ScrollViewer, but I still have no idea... the solution must NOT go throught all items to test if they can be seen, because this would be too slow.I'm not sure code or xaml would be usefull, it is just a Virtualized/Recycling ListView with its ItemSource bound to an Array.
