Currently, you cannot disable all columns in the column menu - it requires that at least one column is enabled.
However, if the grid contains any non-hidden columns which have IncludeInMenu=false, then it should be possible to disable all the remaining columns using the column menu.
Hello Martin,
There have been recent improvements involving hiding columns from the column menu. Would you upgrade the components to the latest version and see how it works for you? The current version is 2019.3.1023.

Has this been changed in a recent update? It is certainly not my experience with version 2018.1.221. You cannot un-check all columns in the column menu - even if there are other displayed columns. In this example, the 'Name' column is not included in the menu - but the column menu will not allow me to un-check 'Staff Type' unless I check another column first.
Hello Martin,
The behavior you describe is available out of the box. When a column is not included in the column menu all other columns can be hidden. To exclude a column from showing in the column menu use the columns.menu option.
