The Parameters tab enables you to create and modify parameter values, input controls, and customize parameter conditions. You may also bind parameters to controls and chain controls to one another. The Parameters tab consists of the following components:

• Input control objects.

  You may select the input control object to view and edit the Properties and settings of the control.

  • Creating an input control from the Design view prompts you to create a bound parameter on the Parameters tab.
  • Editing an input control, which is inserted when setting input controls for new parameters.
• Add new parameters.

  Right-click anywhere on the Parameters tab to add a new parameter.

  Note: Manually adding a parameter creates an unbound parameter.

• Refresh unresolved parameters.

  All parameters on the parameters tab are parsed every two minutes to check if any are unresolved. If there are any unresolved parameters, their surrounding polygon is colored red. If you want to check for unresolved parameters on demand, right-click and select Refresh unresolved.

• Binding controls and parameters.

  Input controls and parameters can be bound and unbound from the Parameters tab.

  You may bind a parameter to an input control, or bind an input control to a parameter.

  • Binding a parameter to a control makes it an incoming parameter that will populate the control. Drag a parameter object to a control object on the Parameters tab.
  • Binding a control to a parameter will populate the parameter. Drag a control object to a parameter object on the Parameters tab.
• Chain one control to another.

  Chaining will populate controls based on the selected value from the prior control in the chain. You can chain static and dynamic controls, link or unlink parts of a chain, and create conditions on links in a chain. Chains are represented by lines connecting control objects on the Parameters tab. By clicking the arrow head in a link of a chain, the Properties and settings dialog box enables you to modify and set properties and conditions of the chain.

  Note: Chaining is applicable only for controls, not parameters.
