You say it "behaves" as if it's readonly. Is it readonly? After you initialize the grid, and break, is the checkbox control itself readonly? Also, maybe since the default when you addobject is that the obj is invisible, do you need to set the visible property?

I suggest creating your checkbox class that looks exactly the way you want it, and addobject _that_ to the column instead of the internal checkbox.

>I am experencing the following problem on a VFP 5 project. When the checkbox is added to the grid it behaves as if it is "readonly". Without the checkbox the column is writeable. I have tried many different sequences of property settings without achieving a solution. Any ideas?
