I have 2 GridViewDataColumn. DisplayIndex of first column is set to 0. DisplayIndex of second column is set to 1. I tried to add my columns to GridViewColumnCollection but DisplayIndex of each column is automatically change to -1.
Please see the attached project for a reference. I create the columns at runtime and set their display index. They are shown as expected. Can you reproduce the problem there?
