I already know that a single hidden column can be masde visible by a call to:
this.gridControl.Cols.Hidden[colIndex] = false;
But how to clear all hidden columns or respectively how to get the number of hidden columns?
Thanks in advance,

You can use grid.Model.HideCols.SetRange to either hide or show columns. There is also a grid.HideCols.ResetRange method you can use to reset whether a range of columns has been hidden. There is no straight-forward way to get a count of hidden column unless you maintain it yourself.
