#Remarks
The OnInitializing
event occurs when the client component is created, before the view model is fetched from the server, and before the BeforeRender
event.
You can handle the OnInitialievent
to patch the initial “get designer model” HTTP request:
onReportDesignerInitializing: function (s) {
DevExpress.Analytics.Utils.fetchSetup.fetchSettings = { headers: { HEADER1: 'VALUE1' } };
//DevExpress.Analytics.Utils.ajaxSetup.ajaxSettings = { headers: { HEADER1: 'VALUE1' } };
}
