Popup Column Picker

You can easily implement a column-picker UI by using the grid's columns property, a ListBox control, and C1 MVC's showPopup and hidePopup methods.

For example, the grid below loads with an auto-generated set of columns. Click the gear icon at the top-left cell to show a ListBox where you can select the columns you want to display.

You can use the grid's columnLayout property to allow users to save and restore column layouts. Click the buttons below to see how this works.
