My RadGrid has several instances where I use a Row Details Template to have a Grid within a grid (if that makes any sense...). I was hoping the rows of the inner grid would inherit the style of the parent grid, but this doesn't seem to be the case. Even if I define a row style in the XAML markup for my inner grid it still doesn't work. But there is no problme at all with the parent grid. All I want to be able to do is make the background of each row transparent. Does anyone have any suggestions on what I might be doing wrong?
