Hello,
Our application has a requirement to automatically log a user out after a period of input inactivity, e.g. keyboard or mouse events for security reasons.
When we automatically log out a user, we also want to close any open modal dialogs in our application, including any modal dialogs open in the Telerik ReportViewer - such as the Export / Print dialogs.
Is there a way for cancel/close these modal dialogs?
I looked at the specific events such as ExportBegin as it provides a way to cancel the export, but I need a way to close the dialogs at any time not just at the specific time the export starts.
Thanks,
Canice.

Hi Canice,
A developer from the Reporting team has already replied to the same question you asked in a Support thread. Here are the highlights related to the technical issue for the benefit of our community. The sample is also attached.
I have attached a sample WPF project that illustrates how to close all child windows within an application (both modal or modeless). A part that can be a bit tricky is the time-related event. Using a DispatcherTimer will not be a viable option as opening a modal dialog will block the dispatcher queue, so that the event should potentially originate on another thread. However, processing the event should be forced on the main thread as all of the application windows are owned by the main thread, and trying to close them on another thread will cause a dispatcher access exception.
