I'm trying to recreate the "drag column to group by it" feature shown in the animation on this webpage:
Neither of the 2 C# projects at the bottom of the page have the drag grouping feature enabled by default.
Trying to drag a column header onto the grouping row causes a "invalid operation" cursor icon to be displayed
Please could you look into this and advise on how to get the demo source code giving the same results as the animation ?
Many thanks in advance,
