Declaration
Property Value
| Type | Description |
|---|---|
| String | The name of a JavaScript function used to handle the DocumentReady event. |
Remarks
The DocumentReady event occurs before the Document Viewer loads a document.
The handler function receives two parameters - the first parameter is the client-side Document Viewer (the event sender) and the second parameter is an object with the following properties and methods:
ReportId
The report ID.DocumentId
The ID of the document that is ready to be shown in the Web Document Viewer.PageCount
The total number of pages in a document.
The following code causes the Document Viewer to flip through document pages:
window.ReportingViewerCustomization = {
onDocumentReady: function (s, e) {
var previewModel = s.GetPreviewModel();
var goToNextPage = function () {
var pageIndex = previewModel.GetCurrentPageIndex();
if (e.PageCount <= pageIndex)
return;
previewModel.GoToPage(pageIndex + 1);
setTimeout(function () { goToNextPage(); }, 3000);
}
goToNextPage();
}
}
