Syntax
<TreeView control>.Display([<Position>])
<TreeView control>: Control name Name of the TreeView control to be refreshed. <Position>: Integer, character or constant (optional) Indicates the start position for the refresh. If this parameter is not specified:- For a TreeView control based on a data file, the function behaves as if the taInit constant was passed as parameter.
- For a TreeView Table control populated programmatically, the function has no effect.
This parameter can correspond to: - An integer. The refresh is performed from this position. The selected row is not modified.
For a TreeView control based on a data file, the "Display a row" event for the <Position> row is executed. The current element in the TreeView control is the same as the current record in the data file. For a TreeView Table control populated programmatically, the <Position> row is re-displayed. - A character or a constant:
