XTREE Enhancement: Vertical radio button groups. Three special Group codes have been set aside 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.
