TreeSelectCount (Function)
 Advertencia
A partir de la versión 24, TreeSelectOccurrence se conserva por motivos de compatibilidad. Esta función ha sido reemplazada por TreeSelectCount.
Returns the number of selected elements in a TreeView control (for a multi-selection TreeView control). The selected rows correspond to the current rows on which the selection bar is displayed. Note: The TreeSelectCount function can be used on both: - a TreeView control populated programmatically, based on a data file, or based on a variable.
- a single-selection or multi-selection TreeView control.
nbOccurrences is int
nbOccurrences = TreeSelectCount(TREE_TreeView1)
FOR i = 1 TO nbOccurrences
Trace("Selected node:" + TreeSelect(TREE_TreeView1, False, i))
END
Sintaxis
<Result> = TreeSelectCount(<TreeView control>)
<Result>: Integer - Number of selected rows in the specified TreeView control. This number can be greater than 1 for multi-selection TreeView controls.
- 0 if no row is selected.
<TreeView control>: Control name Name of the TreeView control to be used.
A WLanguage error occurs if this parameter does not correspond to the name of a TreeView control.
If this parameter corresponds to an empty string (""), the control used will be the TreeView control to which the current event belongs.
