Excel Documents

Displaying Excel Documents

The ImGearExcelBookDocument and ImGearExcelSheetDocument objects can be created and processed in any thread with any apartment state: STA or MTA. If they also need to be displayed, then there are some concepts which should be taken into account:

In WPF display scale mode the calling thread must use the STA apartment state, which is a requirement of Windows Presentation Foundation. ImageGear will create a WPF Canvas in the context of this calling thread to render the document pages for display.
In Native display scale mode, which is the default for ImageGear, there are no restrictions for displaying Excel pages in a multithreaded environment.

ImageGear renders only accepted revision changes of the document; i.e., if it has "Track Changes" enabled, please make sure to accept all/required changes in the document prior to opening it with ImageGear.
