Data Panel

The Data panel is an integrated interface for managing the resources that are used in the current report (to display it, check Data on the Home or View menu tab). The panel consists of a toolbar, a dataset drop-down list, and a field panel as shown below:

Toolbar

The toolbar contains the following buttons:

• Views
  This button varies with the view you select. It is only enabled for page reports that use query resources. It provides a shortcut menu for you to switch among the view modes (Query View, Dataset View, and Dataset List View). The Query View mode lists all available resources for the current selected component in a report. The Dataset View mode also lists all these resources, however with a checkbox on the left of each resource for you to select (for a dataset coming from a hierarchical data source, there are no checkboxes). The Dataset List View mode lists just the resources you are using in the current component of the report.
• Dataset Filter
  Opens the Dataset Filter dialog to add or modify a dataset filter. Available only for page reports that use query resources.
• Search Resource
  Searches for the required resource in the Data panel.
• Edit
  This button is for editing the selected object if it is a query, formula, summary or parameter.
• Properties
  Opens the Properties dialog of the selected object. You can edit the properties as desired.
• Link with Editor
  This button is enabled only for page reports that use query resources. If it is selected, the Dataset drop-down list will show the dataset bound to the currently selected object; or else the drop-down list will always show the dataset you have selected from the drop-down list, until you select another one.

Dataset drop-down list

This drop-down list is available only for page reports that use query resources. It lists all the datasets used in the current report. The first item <Choose Data from...> provides access to creating a dataset.

Fields panel

This panel lists all available resources for the current report in a tree structure. The DBFields, formulas, summaries, and parameters in this panel respond to right-clicking events, and thus provide you with shortcuts for editing them in the same way as you would do in the Catalog Manager data resource tree.

Searching for resources in the Data panel

The Data panel provides you with a search function which enables you to search resources in the leaf node of the resource tree.

1. Click on the Data toolbar to display the Search dialog.

   

2. Provide a search condition in the Search Expression text box. Use "*" to stand for any string, and use "?" to stand for any character.
3. Select the Case Sensitive checkbox if you want JReport to distinguish between uppercase and lowercase characters when searching.
4. Specify the search scope:
   • Selected Resources: JReport will search from the resources you have selected in the Data panel before you bring out the dialog.
   • Search In: If it is selected, JReport will search from the selected data source in the drop-down list.
5. Click the Search button to search for the resource you want.

   The result will be listed in the Search Result panel which has three columns: Resource Name, Resource Type and Resource Path. You can sort the search result alphabetically by clicking the column headers. When you select a result item from the Search Result panel, the resource node that contains the item will be expanded with that resource item highlighted in the Data panel.
