Is it possible to add controls (e.g. an Image) to a cell in the rgGroupCol column?
To illustrate:
In the following diagram, x is the collapse/expand link, and o is the location that I want to insert an image. The image displayed would be dependent on an item of data from its corresponding row.
-------------------------------------
| Column1 | Column 2 |
-------------------------------------
x -- Group 1 Header Row --
-------------------------------------
o | | |
-------------------------------------
o | | |
-------------------------------------
x -- Group 2 Header Row --
-------------------------------------
o | | |
-------------------------------------
...
Thanks!
