title: How to un-highline WPF DataGrid row?
body: <p>I have a WPF DataGrid and I need to select some rows in the DataGrid. After done selecting, the blue highline remains on the row, and I can't figure out how to get rid of it. I tried clicking somewhere else but the blue-highline remains on the row.</p>
