which is the controlsource of the column to which they are bounded ? maybe it's a function and not just a simple field!

>I added them at design time (visually). The checkboxes DO show up when the form is run. They just act as if they're ReadOnly or Disabled or something.

>>>In my form Load method, I create a cursor:
>>>

>>>CREATE CURSOR USERS (USERNAME C(30), LOCK L, userid n(5,0), sendmsg L)
>>>

>>>
>>>I have a grid on my form that is bound to this cursor. The grid has 3 columns, two of which are using checkbox controls as their Current Control value. The checkbox columns both have sparse = .F.. Both checkbox columns have ReadOnly = .F. while the last column (with the default textbox control and sparse = .T.) has ReadOnly = .T.. The grid itself is set to ReadOnly = .F.
>>>
>>>When I run my form, the checkboxes appear correctly (much rejoicing) but I'm not able to check/uncheck either of the checkboxes in any of the rows.
>>>
>>>What do I need to do to be able to allow the checkboxes to be checked/unchecked?

>>>Thanks for your help.
