When I open the Property Builder on a radGridView, select a column under MasterTemplate and go to Advanced everything looks ok. But if i go to Templates, and then back again to Columns, and use Categorized sorting, almost every property says "Object does not match target type". I'm also missing the MaxLength property. A few times everything has seemd right, but no MaxLength property. If I use Alphabetical sort it's ok.
I'm using v2016.2.503.40 and VS2015
