I'm trying to style a RadTreeViewItem to take up all available space in the TreeList width. I have three items of bound data I want to show in a treeitem. The first two being an image and a name, and the last being an image indicating a status that is to be right aligned to the very edge of the treeview where the scroll bar would appear.
In order to do this in a WPF tree view, one has to completely override the treeview item style and use dock panels to change the effect as described here: http://leecampbell.blogspot.ca/2009/01/horizontal-stretch-on-treeviewitems.html
I've tried different forms of Grids and dock panels, but the result always looks the same - as if the items are displayed in a stack panel. I can see that the selected item style actually spans the width of the tree, can I get the item template to display in this manor?
