Loading Panels on Demand

All the panels of a panel stack or filter panel can load when the document is executed, even though only one panel is displayed to the user. This ensures that these pre-loaded panels display immediately when the user selects a different panel. However, if the user is unlikely to access all the panels in a panel stack, or if you want to optimize the initial load time of the document, you can specify that the panels load on demand.

When panels are loaded on demand, only one panel is loaded when the document is executed. Other panels are loaded only when the user selects them. The document therefore opens faster, though panels loaded on demand will take some time to load when they are selected. After a panel is loaded, it remains cached on the client until the document is closed.

On-demand panel loading occurs when the document is executed in XBRi with DHTML enabled. On-demand panel loading does not occur in Flash Mode.

You can define how panels are loaded at two levels:

For all the panel stacks and filter panels in the document (the document-level setting)
For each panel stack and filter panel

This allows you to easily set different panel load settings for different panel stacks. For example, a document contains multiple panel stacks. You want to pre-load all the panels of all the panel stacks, except for the panel stack that contains many panels. At the document level, define the default panel load setting to pre-load all panels. For the specific panel stack, specify that only the current panel is pre-loaded.

To specify the default panel load setting for all panel stacks in a document

The document-level setting applies to all panel stacks and filter panels that use the default panel load setting. You can change the panel load setting for specific panel stacks as well, as described in To specify how to load panels for a specific panel stack.

Note: This setting applies to all layouts of a multi-layout document.

Open the document in the Document Editor.
From the Tools menu, select Document Properties. The Document Properties dialog box opens.
Select Advanced.
Choose one of the Pre-load options:
- To pre-load all panels when the document is executed unless the panel load setting for a specific panel stack is defined differently, select All panels of all panel stacks.
- To load only the current panel of all the panel stacks in the document, select Current panel only of all panel stacks. Other panels are loaded when the user requests them.

Click OK to return to the document.

To specify how to load panels for a specific panel stack

Open the document in the Document Editor.
Right-click the panel stack to modify and select Properties. The Properties dialog box opens.
Select one of the following Pre-load (DHTML only) settings:
- To use the document-level setting, select Inherit from document.
- To pre-load all panels when the document is executed, select All panels.
- To load only the current panel when the document is executed, select Current panel only.

Click OK to return to the document.
