Selecting requests in list view and tree view tables

The following figure compares a list view and a tree view derived from the same source form. The list view columns display the source field names, and its rows display the field data. In the tree view, the field data is all that appears.

List view versus tree view


When users click a row in a list view, they select only one request. To select multiple requests, they must click multiple rows while pressing the Shift or Ctrl key.

In a tree view, a node can represent one or more requests. For example, if a user selects D in the previous example, all the requests under D (x and y ) are selected. If more than one request is selected, the first request (in this example, x ) is considered the primary request, and the other requests are secondary. Workflow uses the primary request for all field value references except those in table loop guides. In table loop guides, all the requests (primary and secondary) are processed in turn. Be aware of this functionality when creating workflow for tree views (see Workflow considerations for table fields).

 Refreshing tree view tables

Unlike list view table fields, tree view table fields do not include operations such as Refresh or Select All.

To display data in a tree view table field when a user opens a form in a mode other than Modify, you must create a Change Field action that refreshes the field when the form is loaded. See Change Field action.

For information about refreshing tree view table data in Modify mode, see Refresh on Entry Change.

NULL values in tree view table fields

NULL values are displayed in tree view table fields as follows:

• When users select a parent node and any of its child nodes have data, all child nodes (including NULL nodes) are displayed.
• If all child nodes are NULL, the first child node appears, but the rest of the nodes are collapsed.
• If a parent has only one child and that child is NULL, the child is not displayed.

NULL data is represented with the words No Value in brackets ([No Value]) unless you specify a different string for the tree view table field's Display NULL Value As property.
