C# – Styling a selected ListViewItem in Windows 8 CP


I want to change the appearance of the Border of the selected Item in the picture linked below.

enter image description here

I've already been looking around on msdn.com and on the internet, but I've found nothing useful.

How can I do this?

The selection appearance is part of the ControlTemplate for ListViewItem. To modify the template for an entire ListView use the ItemContainerStyle to apply a Style to each item, which can contain a modified version of the template.

    <Style TargetType="ListViewItem">
      <Setter Property="Template">
          <ControlTemplate TargetType="ListViewItem">

The default template for ListViewItem is pretty complex so in order to preserve as much of the default behavior as possible and give you a good starting point, it's easiest to use Blend to create a copy for you.

In Blend, right-click your ListView and select:

Edit Additional Templates -> Edit Generated Item Container -> Edit A Copy...

and it will create a Style for you in the form above with the default template filled in. The selection appearance uses a few different elements in the template which you may want to modify - these can be seen by selecting the Selected state in the States panel in Blend and drilling into the highlighted items in the Objects panel.
