Printing GridControl in Server Mode causes NullReferenceException

created 9 years ago

[DevExpress Support Team: CLONED FROM T318038: Issues with NavigationFrame and Prinpreview for ServerMode GridControl]
Hi,

Attached is a sample project that shows the issues i have encountered while creating a printpreview of a gridcontrol bound to a WcfInstantFeedbackDataSource.

The MainWindow contains a NavigationFrame control and a gridcontrol. I navigate to a another view to show the printpreview.  The PrintPreview view contans an AppBar control with an AppBarBackButton.
My real project needs to set the dataservicecontext merge option to MergeOption.OverwriteChanges .

When i navigate back to the MainWindow from PrinPreview view i get a null reference exception.This exception doesn't occur if i remove the merge option setting.

How can i overcome this issue?

Thanks.
