grid.Columns().hide() question

[kshipra]

I came across this documentation, where cols can be manipulated.  If export is clicked I would like certain cols to be always exported even though they are not visible.

I would like to always have columns 'Id' and 'Updated' exported, so I am trying to make it visible so they will get exported.
I am not sure how I need to pass parameters to this:

I am trying to do something like this. --- Need help here.
 this.Columns().hide("diShow", ["Id", "Updated"]);


It is giving me error.

Correct syntax is

Code: [Select]

this.Columns().hide(
  { diShow: ["Id", "Updated"] }
);

where this is reference to grid instance.
