TdxCustomTreeView.LoadFromFile(string) Method

Loads node captions and positions in the Tree View control from the specified plain text file.

#Declaration

Delphi
procedure LoadFromFile(const AFileName: string); overload;

#Parameters

Name Type Description
AFileName string

A source file name.

#Remarks

The LoadFromFile procedure uses the system encoding to load node captions and positions. If the specified file’s encoding differs from the system encoding, call the LoadFromFile(System.String,System.SysUtils.TEncoding) procedure instead.

A LoadFromFile procedure call raises the EdxTreeViewException exception if the loaded information is not valid.

Note

You can call a SaveToFile procedure to save node captions and positions to a plain text file. The LoadFromFile procedure does not support files created by a SaveDataToFile procedure call.

The LoadFromFile procedure raises the OnAddition event for each loaded node.
