Using a parameter gadget
Parameter gadgets display parameter choices from a BIRT file on the dashboard. Other report or Reportlet gadgets on the same dashboard can use these parameters when the BIRT file they display require parameters. A BIRT developer can add parameters to a BIRT file.
Parameter gadgets present all or selected parameter choices that the BIRT document or design file includes, as shown in
Figure 3‑6. When the BIRT file displayed in the report or Reportlet gadget requires static parameters, these parameters can be linked to a data visualization gadget instead of a parameter gadget. Static parameters request a value from a user. Dynamic parameters request a value and a condition.

When editing this gadget, you can assign default values to selected parameters. Dynamic parameters, if available in the BIRT file, can also be assigned default conditions in addition to the value, as shown in
Figure 3‑7.

Dynamic parameters enable additional flexibility for a user to select and explore data using a variety of condition operators and values. Default condition operators and values appear in the gadget. A user can change both the operator and value on the dashboard.
The BIRT report developer adds one or more conditions to display in a dynamic filter parameter. For more information about parameters, see
Displaying report parameters, later in this section.
Dashboard developers can customize the display of parameter gadgets using Edit Parameter Gadget—General options. For more information about general options, see
Setting general gadget options, earlier in this section.
