Description |
| object | Required. A reference to a valid tree component object. |
| integer | Required. The setting 0 specifies that all records are to be queried into the tree (unlimited). The setting -1 specifies that the default cap for the IDO is to be applied. Any positive integer specifies the maximum nodes at each level. |
By default, IDO collections in a tree component use the cap that applies to drop-down lists. This cap is set from the WinStudio View menu, Settings window, Runtime tab, Caps section, Drop-downs settings.
This method overrides the drop-down list setting for a particular tree component. To change the cap dynamically, refresh the tree using the TreeRefresh method after you have changed the cap.
Sub Main()
Rem Set the cap to 10 nodes per level.
