Question

So this is pretty mystifying. I have a databound ListBox (or ListView, it happens with both), and if it has more than 2 items in it, selection works – I get a blue highlight bar and the item looks selected. If I only have 1 item, the selection does not work – I do not get a blue highlight bar, but the selection events all fire as normal. Is this a bug in WPF? Or am I just crazy?

This is how I’m setting up my ListBox:

    <ListView x:Name="plotListBox"
             DockPanel.Dock="Bottom"
             ItemsSource="{Binding Path=Plots}"
             SelectedItem="{Binding Path=SelectedPlot, Mode=TwoWay}"
             SelectionMode="Single"
             ScrollViewer.CanContentScroll="False"/>

Has anyone else run into something like this?
This post seems to describe a similar issue, but I can’t find anything in the replies that I think would help my situation.

Answer 1

Wow, the culprit was ScrollViewer.CanContentScroll="False". Everything worked fine once I pulled that out.
