Example

Executing the example requires a form with the Button1 button, the LanerBox component named LanerBox1 and the UiErAnalyzer component that is a data source for LanerBox. A workbook of the time series database should be loaded to UiErAnalyzer1.

This procedure should be assigned as a handler of the OnClick event for the button. The example is executed on clicking the button.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Begin
    If LanerBox1.CanExecuteOperation(LanerBoxOperation.ChangeMode) Then
        LanerBox1.ExecuteOperation(LanerBoxOperation.ChangeMode);
    End If;
End Sub Button1OnClick;

After executing the example data display mode is changed for the workbook displayed in the LanerBox component if possible.
