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 occurs.
You can handle the OnInitializng
event` to patch the initial “get designer model” HTTP request:
onInitializing: function (s) {
s.dx.Analytics.Utils.fetchSetup.fetchSettings = { headers: { HEADER1: 'VALUE1' } };
//s.dx.Analytics.Utils.ajaxSetup.ajaxSettings = { headers: { HEADER1: 'VALUE1' } };
}
