Hide column method in api

[zaknuces]

I need to hide / show columns of the grid after it is loaded (based on some permissions). I wasn't able to find a method in the grid api to call that can do it for me.

As a workaround, i am doing what hide column context menu is doing. Something like:

this.gridApiInterface.grid.columns[0].colDef.visible = hasDeletePermission;
this.gridApiInterface.grid.columns[0].visible = hasDeletePermission;
this.gridApiInterface.grid.queueGridRefresh();
                    this.gridApiInterface.grid.api.core.notifyDataChange(uiGridConstants.dataChange.COLUMN);                    this.gridApiInterface.grid.api.core.raise.columnVisibilityChanged(this.gridApiInterface.grid.columns[0]);

Having a quick method to do it would help.

Secondly, it will also be worthwhile to expose method to update 'enableRowHeaderSelection' property to control the visibility of selection column.

col.showColumn()

Thanks @lpand! Not sure who manages the ui-grid.info site, but it would be lovely if the tutorial on adding/removing columns mentioned these extremely helpful functions.

I'm glad i helped you. Hey, you could make a pull request to fix that :).

Doing col.hideColumn or col.showColumn doesn't update the visible state of the column sometimes. I am unable to reproduce this behaviour consistently. However, when i add the following after showColumn or hideColumn:

grid.api.core.notifyDataChange(uiGridConstants.dataChange.COLUMN);

it seems to work every time.

Is there any relation between them that is causing race condition?
