I'm trying to pass a DataSet with two Data Tables to fill text boxes in the report header and report lines of the report. When I step the code and do a watch on the report, the text values are showing the correct values from the dataset, but when the report is displayed on my web form they are not there. It will just use the value of the textbox frpm design time? How do I get the report viewer to display the report with updated textbox values? I set the a report object equal to the method to update the textboxes that returns the updated report, then set that to the reportviewer's report property as I've seen in examples, but the textbox values are not updating?
