Example

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 working area 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, Tab, and Ui system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Serie: ILanerSerie;
Begin
    If LanerBox1.SelectedSeriesCount > 0 Then
        Serie := LanerBox1.SelectedSeries(0);
        If Serie.IsChanged Then
            WinApplication.InformationBox("Series data was changed");
        End If;
    End If;
End Sub Button1OnClick;

After executing the example the message is displayed if the data of the series, that is selected in working area, was changed.
