Methods

refresh Method

Reopens an assigned report.

Declaration

refresh(): void

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.

<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"/>
