How to disable sorting of XtraTreeList users?

Question

I show a fixed sequence in the list of trees along with some values, and clicking on the header sorts it by the value in the column belonging to the header.

I did not find any obvious XtraTreeList property that would prevent this sorting.

Answer 1

Sorting is disabled for each column. You cannot disable the entire list of trees.

Answer 2

For each column of your TreeList, disable AllowSort- this is one of the sub-properties listed in OptionsColumn.
