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