The following code example shows how to use the CachedDocumentSourceDeserialized method to obtain the Product Category that is used to rename worksheets in an exported XLSX file. The report displays the category on the page from which the worksheet originated.
public override void CachedDocumentSourceDeserialized(string documentId, CachedDocumentSource cachedDocumentSource, GeneratedDocumentDetails documentDetails, DocumentStorage documentStorage) {
if(documentDetails.CustomData != null && documentDetails.CustomData.TryGetValue(CustomPageDataService.Key, out object customData)) {
var customDataServiceDictionary = ((object[])customData).Cast<KeyValuePair<int, CustomPageData>>().ToDictionary(x => x.Key, x => x.Value);
if(customDataServiceDictionary == null)
return;
var customPageDataService = new CustomPageDataService(customDataServiceDictionary);
cachedDocumentSource.PrintingSystem.XlSheetCreated += customPageDataService.PrintingSystem_XlSheetCreated;
}
}
