CustomItemDrawers
Gets the drawers for CustomReportItem types, keyed by the item's Type.
public IDictionary<string, ReportCustomItemDrawer> CustomItemDrawers { get; }Property Value
Remarks
A custom report item is RDL's extension point: its Type names something whose
meaning lives outside the definition, so an engine that guessed at one would be guessing at what
only its author knows. A host that knows what a type means registers a drawer here, and the item
is drawn from the shapes it returns.
An item with no registered drawer falls back to the built-in barcode drawer when its type
names one, then to nothing with DXP9406. Registering a drawer for Barcode replaces
the built-in one.
A drawer is called during pagination, from whatever thread paginates, and must be thread-safe. It is called once per item instance. An exception it raises is reported and the item is left undrawn, rather than failing the whole report.
