Group=###
Associates radio button cells within the current column with a specific radio button group, so as to allow more than one group of radio buttons in a row, or even a set of related cells in the same column to form a group. ### is the group number, 0-252. Columns without a Group= clause are assigned group 0. Groups 253-255 are reserved for vertical groups:
|
Group |
Description |
|
255 |
Entire column is a single group |
|
254 |
XTF_MLVL: Items with same immediate parent form a group |
|
253 |
XFF_MLVL: Items at same level form a group |
If the tree is not multi=level, all three of the above act like 255, i.e. only one radio button in the entire column can be selected at a time.
Note that as with horizontal groups, enforcement of the only-one-selected-per-group rule occurs only when you change a radio button during editing. It is up to the application to enforce the rules during loading and display operations.
