Type Description

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


The CustomizeElements event enables you to customize the Web Report Designer’s UI elements. 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.

  • Elements
    A collection of the Web Report Designer’s UI elements.

  • GetById
    This method allows you to obtain the required element by its ID using the DevExpress.Reporting.Designer.Utils.ReportDesignerElements object. The following elements are available within this object:

    • MenuButton - the menu button in the upper-left corner of the Designer’s user interfaces.
    • NavigationPanel - the panel at the bottom of the Designer displaying opened report tabs.
    • RightPanel - the panel at the right of the Designer and containing tabs with the Field List, Report Explorer and Properties Panel.
    • Surface - the design surface.
    • Toolbar - the Report Designer Toolbar.
    • Toolbox - the Toolbox containing report controls.

The code sample below demonstrates how to use this event to hide the Report Designer’s Toolbar.

    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.CustomizeElements("customizeElements"); });
