The name of a JavaScript function or the entire JavaScript function code used to handle the ReportTabClosing event.


Type Description

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


The ReportTabClosing event enables you to respond to closing a report tab 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.

  • ReadyToClose
    Specifies the JQueryDeferred object that when resolved, forces the report tab to be closed.

  • Handled
    Specifies whether or not the event was handled.

  • Tab
    Specifies the report tab currently being processed.

The code sample below demonstrates how to use this event to prevent closing a specific report tab.

    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.ReportTabClosing("reportTabClosing"); });
