Type Description

A ReportDesignerClientSideEventsBuilder that can be used to further configure the Report Designer Client Side Events.


The ReportOpening event enables you to perform required actions before a report is opened in the Web Report Designer. When implementing a handling function, use the objects passed as parameters. The first parameter passes the event sender that is the ClientReportDesigner object. The second one is an object with the following structure.

  • Url
    The URL of the report currently being processed.

  • Report
    The report currently being processed.

  • Cancel
    Specifies whether to cancel opening the report.

The code sample below demonstrates how to use this event to prohibit opening reports with URLs containing a specific substring.

    var designer = Html.DevExpress().ReportDesigner("reportDesigner1").Height("1000px")
        .DataSources(configureDS => { foreach (var ds in Model.DataSources) { configureDS.Add(ds.Key, ds.Value); } })
        .ClientSideEvents(configure => { configure.ReportOpening("reportOpening"); });
