Example

The following code demonstrates how to save a modified report in the active tab, and how to save all modified reports in the Report Designer.

ASP.NET Core

<script type="text/javascript" id="script">
    // Saves a modified report in the active tab
    // and clears the modification flag.
    function saveCurrentReport() {
        if (reportDesigner.IsModified()) {
            reportDesigner.SaveNewReport("Rep1");
            reportDesigner.ResetIsModified();
        }
    };
    // Saves modified reports in all tabs,
    // clears the modification flags,
    // displays a message when the report is successfully saved.
    function saveAllReports() {
        var tabs = reportDesigner.GetTabs();
        tabs.forEach(tab => {
            if (tab.isModified()) {
                if (!tab.url()) tab.url('Report' + Date.now());
                reportDesigner.ReportStorageSetData(tab.context().report.serialize(), tab.url())
                    .done(function (result) {
                        tab.resetIsModified();
                        DevExpress.Analytics.Internal.ShowMessage(DevExpress.Analytics.Utils.getLocalization("The report has been successfully saved.",
                            "ASPxReportsStringId.ReportDesigner_SaveReport_Message_OK"), DevExpress.Analytics.Internal.NotifyType.success);
                    });
            }
        });
    };
</script>

</script>

report Property

Specifies a report opened in the current tab.

Declaration

report: ko.Computed<DevExpress.Reporting.Designer.Controls.ReportViewModel>

Property Value

Type
Computed<ReportViewModel>

undoEngine Property

Specifies an engine that manages undo and redo operations in the Web Report Designer.

Declaration

undoEngine: DevExpress.Analytics.Utils.UndoEngine

Property Value

Type	Description
UndoEngine	An object that specifies an undo/redo engine.

url Property

Specifies the URL of a report opened in the current tab.

Declaration

url: ko.Computed<string>

Property Value

Type	Description
Computed<string>	A knockout computed string that specifies the report URL.

Methods

refresh(resetState) Method

Reopens an assigned report.

Declaration

refresh(
    resetState: boolean
): void

Parameters

Name	Type
resetState	boolean

Remarks

The refresh method reopens a report assigned to the current tab without saving changes made to this report. This method works only if you implemented a custom server-side report storage.

The following code snippet demonstrates how to use the client-side GetCurrentTab method to get the currently active Report Designer tab and reopen an assigned report.

ASPX

<script type="text/javascript">       
    function Refresh() {
        var tab = reportDesigner.GetCurrentTab();
        tab.refresh();
    }
</script>

<div onclick="Refresh()">Refresh</div>
<dx:ASPxReportDesigner ID="ASPxReportDesigner1" ClientInstanceName="reportDesigner" runat="server" />

resetIsModified Method

Resets the value returned by the isModified property.

Declaration

resetIsModified(): void

Remarks

The following code snippet demonstrates how to reset the isModified property value for all Report Designer tabs. To obtain these tabs, use the GetTabs method.

 <script type="text/javascript">
    function ResetIsModified() {
        reportDesigner.GetTabs().forEach(function (item) { item.resetIsModified(); })
    }
</script>

<div onclick="ResetIsModified()">Reset IsModified</div>
<dx:ASPxReportDesigner ID="ASPxReportDesigner1" ClientInstanceName="reportDesigner" runat="server"/>
