I have a button on my ASP.NET webforms project that once clicked will open a kenodoWindow whose content is another web page in the same project. All forms load correctly except for one with a report viewer tool. Once clicked The KendoWindow pops open and the toolbar for the reportviewer tool, however it doesn't load the actual reports to display. When I try opening the same page in its own webpage and not a Kendo Window the reports load fine in the tool. So my kendoWindow seems to be working fine, and reportviewer tool also works fine. Any reason why these two dont seem to work together?
