When I work with groups of columns, and I try to show a group that not is the first one, columns header aren't displayed in correct order. As you can see in the example, what could I do to do that?
Indeed this is bug. This issue has been fixed for the next internal build, which should be released by the end of the week. When it is released, please upgrade and let us know if the problem persists.
As a token of gratitude for bringing this problem to our attention I've updated your Telerik points.
