[Solved] showColumn/hideColumn not hiding header

[Dan]

When I call the hideColumn() method what's happening is that the data in the column is being hidden and all the data to the right is sliding over to take its place. Meaning if I call hideColumn on column B, all the data for column C is now under column B but the column B header is still visible. The weird part is that if I right click on the column headers to get the context menu, column B is now unchecked like I'd expect but the header is still showing. Any solution for this?

So it turns out adding a timeout makes it work.

setTimeout(function() {  
                            parentGrid.hideColumn(val.member);
                        }, 250);

Why is this? Is there some asynchronous call going on in the background when hideColumn is called?
