JSReportDesigner Class

A client object that is the sender for the Report Designer client-side events. Provides access to the client-side Report Designer API.

Declaration

export class JSReportDesigner

Remarks

To get access to the client-side Report Designer API, obtain the JSReportDesigner object as described below.

Add a callback for the BeforeRender client-side event to the the dxReportDesigner Knockout binding code that integrates the Web Report Designer in the JavaScript framework. The event sender is the JSReportDesigner object.

The following code gets the JSReportDesigner object and stores it in the varJSReportDesigner variable:

import React from "react";
import ko from "knockout";
import 'devexpress-reporting/dx-reportdesigner';
// ...

class ReportDesigner extends React.Component {
    constructor(props) {
        super(props);
        this.reportUrl = ko.observable("TestReport");
        this.designerModel = ko.observable();
        this.requestOptions = {
            // ...
        };
    }

    render() {
        return (
            <div
                ref="designer"
                data-bind="dxReportDesigner: $data"
                style={{ width: "100%", height: "100%" }}
            />
        );
    }
    componentDidMount() {
        var self = this;
        ko.applyBindings(
            {
                callbacks: {
                    BeforeRender: function(s, e) {
                        self.varJSReportDesigner = s;
                    }
                },
                reportUrl: this.reportUrl,
                designerModel: this.designerModel,
                requestOptions: this.requestOptions
            },
            this.refs.designer
        );
    }
    // ...
}

CloseTab(tab) Method

Closes the specified report tab

Declaration

CloseTab(
    tab: any,
    force?: boolean
): void

Parameters

Name Type Description
tab any

Specifies the Report Designer tab to close.

force boolean

True to silently close the tab; false to show the Save Report dialog. If omitted, the value is false.

Remarks

The CloseTab method closes the specified Report Designer tab.

The force parameter value determines whether or not to show the Save Report dialog if the report in the tab contains unsaved changes, as follows:

True
the tab is closed without notification. Changes are not saved.
False
the Save Report dialog is invoked.

To access all available Report Designer tabs, call the GetTabs method.

Use the CloseCurrentTab method to close the currently active tab.

The following code snippet demonstrates how to use the method.

<script type="text/javascript">
  function CloseSecondTab() {
      var tabs = reportDesigner.GetTabs();
      reportDesigner.CloseTab(tabs[1]);
  }

  function ForceCloseSecondTab() {
      var tabs = reportDesigner.GetTabs();
      reportDesigner.CloseTab(tabs[1], true);
  }
  function CloseCurrentTab() {
      reportDesigner.CloseCurrentTab();
  }
</script>

@{
    var designerRender = Html.DevExpress().ReportDesigner("reportDesigner")
        .Height("1000px")
        .Bind("TestReport");
    @designerRender.RenderHtml()
}
TIP

      if (info.defaultVal == "Black") info.disabled = true;

      // Get the XtraReport's property that is located in the "Watermark" section and has the "Image Alignment" display name.
      info = s.GetPropertyInfo("DevExpress.XtraReports.UI.XtraReport", ["Watermark", "Image Alignment"]);
      // Hide the property in the Property panel.
      info.visible = false;

      // Get the XtraReport.DrawWatermark property.
      info = s.GetPropertyInfo("DevExpress.XtraReports.UI.XtraReport", "DrawWatermark");
      info.visible = false;

      // Get the Separator property (found in the XtraReport.ExportOptions.Csv.Separator path).
      info = s.GetPropertyInfo("DevExpress.XtraReports.UI.XtraReport", "ExportOptions.Csv.Separator");
      info.visible = false;

      // Get the property of the XRLabel class with the "Can Grow" display name.
      info = s.GetPropertyInfo("XRLabel", "Can Grow");
      info.disabled = true;

      info = s.GetPropertyInfo("XRLabel", "EditOptions");
      info.visible = false;
    }
</script>

@{
    var designerRender = Html.DevExpress().ReportDesigner("reportDesigner")
        .Height("1000px")
        .ClientSideEvents(configure=>configure.BeforeRender("onBeforeRender"))
        .Bind("TestReport");

}

GetTabs Method

Returns open tabs in the Report Designer.

Declaration

GetTabs(): DevExpress.Reporting.Designer.Tools.INavigateTab[]

Returns

Type Description
INavigateTab[]

An array of Report Designer tabs.

Remarks

Use the GetTabs method to obtain all open tabs in the Web Report Designer.

The following code gets all tabs and closes the second tab:

<script type="text/javascript">
    function CloseSecondTab() {
        var tabs = reportDesigner.GetTabs();
        reportDesigner.CloseTab(tabs[1]);
    }
</script>

@{
    var designerRender = Html.DevExpress().ReportDesigner("reportDesigner")

        .Bind("TestReport");
    @designerRender.RenderHtml()
}

IsModified Method

Indicates whether a report in the Report Designer’s active tab is changed.

Declaration

IsModified(): boolean

Returns

Type Description
boolean

True if the report has been modified; otherwise, false.

Remarks

Use the IsModified property to determine if a report in the current tab is modified. After you save the modified report (or take another action to process it), call the JSReportDesigner.ResetIsModified method to clear the modification flag.

You can also use the NavigateTab.isModified property to determine whether a report loaded to a particular tab is modified.

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.

<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>


@{
    var designerRender = Html.DevExpress().ReportDesigner("reportDesigner")
        .Height("1000px")
