I know how to create a tooltip for datagrid and/or its
columns. Is it possible to create a tooltip (or something similar)
for each cell? So whenever the mouse is over a certain cell, a tip
would be shown for that cell that depends on the value of the cell.
Similar functionality can often be seen in web-based database apps:
an Ajax query gets related data from a database on mouseOver.
My need and idea is to
- show a simple text list as a tooltip
- the text would be fetched from a database via a web service
- the fetch would be based on datagrid's (hidden) rowid and
each column's (hidden) column id (which are real database columns)
- the database structure is an n:m relation i.e. one
rowid+colid can refer to several items that are then used in the
Use case: A number is displayed in the datagrid. The need is
to display 0-n references related to that specific figure (e.g.
book names, notes etc) in the tooltip. Next cell's tooltip would be
showing different references.
