    Property Value

    Type Description
    String

    The name of a JavaScript function used to handle the ReportOpening event.

    Remarks

    Handle the ReportOpening event to prevent certain reports from being opened.

    The handler function receives two parameters: the first parameter is the client-side Report Designer (the event sender) and the second parameter is an object with the following properties and methods:

    Url
    The URL of the report currently being opened.
    Report
    The report currently being opened.
    Cancel
    Specifies whether to cancel opening the report.

    The following code does not allow the Report Designer to load reports with a URL that contains the “table” substring:

    window.DesignerCustomization = {
        onReportOpening: function (s, e) {
            if (e.Url.toLowerCase().includes("table"))
                e.Cancel = true;
        }
    }
