                                    Hello,
                                    unfortunately the patch does not fix the problem completely. The text marking is done as desired, but in the following there is still the problem that a call of

                                    .DocumentLayout.GetPageCount

                                    crashes the program.

                                    The following procedure to reproduce the problem:
                                    - mark the second paragraph
                                    - Assigning the marker (e.g. yellow)
                                    - Try to determine the page number (yellow key)

                                    Thank you very much for your help.
                                    Thomas

                                  Hi!

                                  I need information about this error.

                                  Our app is getting blocked when it calls DocumentLayout.GetPageCount method if IsDocumentFormattingCompleted value is true.

                                  Questions:

                                  1. Does the error occur in devexpress version 18?
                                  2. Are there more methods in DocumentLayout that can be blocked if IsDocumentFormattingCompleted value is true?

                                  Thanks for help,
                                  David C

                                  Hi David,

                                  This issue should not occur in version 18.1-18.2.
                                  We are not aware of other cases when the IsDocumentFormattingCompleted property returns true when document layout calculation is not completed yet.

                                  The problem is not about the value returned in IsDocumentFormattingCompleted  property, the real problem I had described is because thread become blocked when call DocumentLayout.GetPageCount method if IsDocumentFormattingCompleted value is true; DEVEXPRESS version 18.1.6.

                                  Please, I need an answer for the questions.

                                  Thank you for your clarification, David. Since the issue you described is not related to the problem described in this thread, I've created a separate ticket on your behalf (T814426: The DocumentLayout.GetPageCount method call hangs even if the IsDocumentFormattingCompleted property returns true). It has been placed in our processing queue and will be answered shortly.
