Changing advStringGrid column width in runtime

I cannot change the column width for the advStringGrid in runtime. I set "goColSizing" till TRUE.
I even add it by code:

asg.Options := asg.Options + [goColSizing];

But I still cannot resize the column in runtime.

Is there any other settings that overwrite goColsizing?

PS: I do not have fixed rows and columns.


Sorry, at this moment, all column sizing is happening from the first fixed row(s) in the grid when goColSizing = true in grid.Options.
There is currently not a built-in option to allow the resizing from other (non-fixed) rows unfortunately.
