I have a grid with about 12 columns. I included a “Columns” button in my tool bar. When my user clicks it, the column option panels are shown, but most are dimmed (disabled) and must be included in the grid. Why is this happening? How can I make all the columns includable or excludable? Thanks in advance for any help you can provide.
Hello Boxer55, I have this exact same problem. Did you get a solution for it?
