• No Look-Up - set the Value to use a static value as a parameter.
• Static List - click the ellipsis button to add static values for the current dashboard parameter.
• Dynamic List - allows you to use a list of values from the existing data source as a parameter. Specify the following settings.
  • First, select the required Data Source from the list of available data sources. For example, if you wish to filter job list by PM, add a new data source linked with Contacts table.
  • Then, specify data members for the dashboard parameter's value and display name using Value Member and Display Member, respectively.
  • If necessary, specify the data member used to sort parameter values using the Sort By option. Sort Order specifies the required sort order.
  • From now, you can use parameters to filter QuickReport's data source (Data source tab - Filter) or in calculated fields. When you double click on a QuickReport to generate it, you will be able to provide parameter value in the Parameters dialog.
