While I searched for a solution to my Keyboard issue
I noticed when I scroll via mouse (horizontal scrollbar) that some columns that are shown after scrolling contain values from colums that were displayed earlier before I scrolled. Is this a redraw bug or does the Grid internally mix the data?
In your official demo
I see no scrollbars. I have 20 columns in the grid which are autogenerated from the underlaying source (AutoGenerateColumns="true").
