Entry List Wizard: Configure Input

The Configure Input step of the Entry List wizard enables you to specify the values required by the selected data service to retrieve the output for the entry list.

The Configure Input step contains the following items:

Item	Description
Mapping area	Displayed only when there are multiple input ports on the selected data service. The left side of the mapping area displays the output port of the UI element, and the right side displays the input ports of the selected data service. You map the output port of the UI element to the input port of the data service by dragging from the port on the left to the relevant port on the right. You can map the output port to multiple input ports. You can delete a mapping by right-clicking the relevant mapping line and choosing Delete Mapping from the context menu.
Target Field	Displays the list of fields for which the data service requires input. The fields displayed depend on the input port selected in the mapping area (if the data service has multiple input ports). The field type (for example, string or date) is indicated by an icon next to the field name. More information: Define Data.
Assigned Value	Enables you to enter the values required by the data service to retrieve the values used to populate the entry list. If the data service has multiple input ports, you can only enter values for input ports that you have mapped in the mapping area. You can enter values in one of the following ways: Enter free text: Type a value directly in the Assigned Value field of the relevant row. Assign a field value: Select a field from the dropdown list in the Assigned Value field of the relevant row. The dropdown list contains fields of the same type as the target field type, which are located in the same UI element as the control for which you are defining the entry list. Define a dynamic expression: Select Define expression from the dropdown list in the Assigned Value field of the relevant row. Use the Dynamic Expression Editor dialog box to define an expression that returns a value of the same type as the target field type. More information: Dynamic Expression Editor Dialog Box
