>I have a grid on a form. It has 2 columns, a checkbox and a text box. I would like to disable certain rows (actuallly the checkbox) from being able accessed, i.e. clicked on, so that I can show the user there are certain rows but they cannot choose them. Is there a way to do that?

1. You can use When logic of the checkbox

2. You can set column to readonly in AfterRowColChange method of the grid depending on condition (that's the method I often use).

If you want this to be applied to multiple rows, then one of the ways is to use dynamiccurrentcontrol with enabled and disabled checkboxes.
