IUiErAnalyzerDataRefreshEventArgs.IsDataChanged

Syntax

IsDataChanged: Boolean;

Description

The IsDataChanged property returns the attribute of modified data in the express report.

Example

Executing the example requires a form with the Button1 button, the UiErAnalyzer component named UiErAnalyzer1 and the TabSheetBox component named TabSheetBox1. Add links to the Express, Pivot and Ui system assemblies.

Class SAMPLEForm: Form
    UiErAnalyzer1: UiErAnalyzer;
    TabSheetBox1: TabSheetBox;
    Button1: Button;
    olap: IEaxAnalyzer;
    pivot: IPivot;

    Sub SAMPLEFormOnCreate(Sender: Object; Args: IEventArgs);
    Begin
        olap := UiErAnalyzer1.ErAnalyzer;
        olap.EnableEdit := True;
        pivot := olap.Pivot;
    End Sub SAMPLEFormOnCreate;

    Sub UiErAnalyzer1OnBeforeDataRefresh(Sender: IUiErAnalyzer; Args: IUiErAnalyzerDataRefreshEventArgs);
    Begin
        If Args.IsDataChanged Then
            If WinApplication.ConfirmationBox("Data is changed and will be lost on updating, save changes?") Then
                Args.SaveChangedData := True;
            End If;
        Else
            WinApplication.InformationBox("Data is not changed");
        End If;
    End Sub UiErAnalyzer1OnBeforeDataRefresh;

    Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
    Begin
        pivot.Refresh;
    End Sub Button1OnClick;
End Class SAMPLEForm;

On executing the example, make changes in a data area cell, and click the Button1 button. The following message appears: Data was changed and will be lost on refreshing, do you want to save the data? If the answer is positive, changes are saved.
