HaveUnsavedData: Boolean;
The HaveUnsavedData property returns whether the workbook contains any series with the unsaved data.
Available values:
True. The series with the unsaved data are present in the workbook.
False. All the data of the workbook series is saved.
Executing the example requires a form with the following components: the Button component named Button1, the LanerBox component named LanerBox1, and the UiErAnalyzer component named UiErAnalyzer1. UiErAnalyzer1 is a data source for LanerBox1. A workbook of the time series database should be loaded to UiErAnalyzer1.
The example is a handler of the OnClick event for the Button1 component.
Add links to the Express, ExtCtrls, Forms, Laner, and Tab system assemblies.
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
Analyzer: IEaxAnalyzer;
Laner: Ilaner;
Series: ILanerSeries;
Begin
Analyzer := UiErAnalyzer1.ErAnalyzer;
Laner := Analyzer.Laner;
Series := Laner.Series;
If Series.HaveUnsavedData Then
Laner.SaveChangedSeries;
End If;
End Sub Button1OnClick;
After executing the example the data of the changed series is saved.
