Hello,
In Q3 hierarchy child grids are sized to take up the entire width available, where as in Q2 they only took up as much space as they required and no more.
(see demo: http://demos.telerik.com/silverlight/#GridView/Hierarchy/CustomHierarchy)
I'm struggling to find a way to replicate this behaviour in Q3, it appears the header control (GridViewHeaderRow) inside the GridViewDataControl template is causing this quirk - if I comment this out (so the headers are not displayed) then the grid behaves correctly and only takes up as much space as it requires. It's as though the header control is adding an "extra" column on the end of my hierarchy child grids and setting the width to star so it stretches right out, without me telling it to.
Help appreciated!
James.
