title: WPF. Splitters between GridViewColumnHeaders
body: <p>Where <code>GridView</code>'s column header splitters are defined? I tried to use Snoop to find them, but I just can't localize template I need.<code>GridViewColumnHeader</code> does not define any splitters. The problem is that default ones are to thin and sometimes It is really hard to select them. Did anyone ever change them?</p>
