Warning
From version 24, TreeSelectOccurrence is kept for backward compatibility. This function is replaced by 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.
Remark: TreeSelectCount can be used on:
  • a TreeView control populated programmatically, based on a data file, or based on a variable.
  • a single-selection or multi-selection TreeView control..
Example
nbOccurrences is int
nbOccurrences = TreeSelectCount(TREE_TreeView1)
FOR i = 1 TO nbOccurrences
Trace("Selected node:" + TreeSelect(TREE_TreeView1, False, i)) 
END
Syntax
<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.
