Is there a way to customize the icon in a checkbox?

I try to set an image list, but it seems they are not supported for cells of checkbox type.

What I need is to "replace" the default square with tick with a custom image (one for 'true', and one for 'false') but with the standard behaviour of a checkbox cell (single click to switch the value)

Is there a way to accomplish this?
Yes, there is a way to redefine the drawing of checkboxes in iGrid cells. You should use the IiGControlPaint interface for that. We have a topic in the electronic documentation that explains how to use this interface:

Another example of this interface usage can be found in the iGrid main demo.
Thank you very much.

I will take a look at this feature, and I will try to implement it
