Type	Description
DevExpress.Web.Scripts.KnockoutObservableBoolean	true, if a dashboard menu item should be disabled; otherwise, false.

For example, the function in the code below returns true when your application does not have any dashboards. In this case, the saveAsItem menu item is disabled.

JS

function onBeforeRender(sender) {
    var dashboardControl = sender.GetDashboardControl();
    var toolbox = dashboardControl.findExtension("toolbox");

    var saveAsItem = {
        id: this.name,
        title: "Save As",
        // ...
        disabled: ko.computed(function () { return !dashboardControl.dashboard(); })
    }
    toolbox.addMenuItem(saveAsItem);
}
