Hi, Steve-
I'm with Ed...I'm not sure what you mean.
You have several columns, each with a checkbox? Then when you click one you want all to be clicked (that sounds a little weird to me for a UI perspective).

Or, do you mean you have a checkbox in a column, and when you check it, each row's checkbox changes? Then you don't need shift-anything. Instead set the column's sparse property to .F.

>I have a grid with checkboxes. If a user clicks on a checkbox, it clears all others. But I want the user to be able to shift-click and select the current one *and* keep the other checkboxes .t.
