Icons are therefore represented physically by a group of related graphic images, each of which corresponds to one of the different icon states.
The naming convention enables these graphic images to be an interrelated set grouped under a single icon.
The appearance of the icon should be different in each case.
This enables the user to understand quickly the current interactivity state of a grid cell.
You can optionally make icons clickable so that a behavior is associated with them.
You can also optionally create tooltip popups to display supplementary information about the data.
You use a QBE value to change the selection criteria of a database fetch.Cells in an update grid can be selected individually.The header detail, headerless detail, power edit, and portlet edit forms have update grids, as do update subforms. The columns are specified at design time and are one of these types: A database column is associated with an item in the business view (BV) and through that connection to a DD item.For example, if a grid column is associated with a dictionary item of type string with a length of 30, that grid column will not permit more than 30 characters to be typed into the cell.Grid controls can also have a query-by-example (QBE) line.Database columns represent a field in a database record.
