Thanks Eric, Both were my code issues and I am able to fix them. The prompt is not displayed because I didn't get the SetString function will return the new string ID for unallocated strings and the second one is due to the reason that I have not passed EndOpCodeHandle for HiiUpdateForm.

Using UpdateForm() in the method you describe seems unusual, since there is no documented behavior about how the Form Browser should handle this behavior. I know it is done often, but using undefined behavior in a driver meant to show sample behavior doesn't seem like a behavior. It seems that this sample is using a lot of non-UEFI features, including custom opcodes. It seems it would be better to focus on standard usage.

Thanks, Eric -----Original Message----- From: Prakash, Sathya [mailto:[email protected]] Sent: Wednesday, February 20, 2013 12:18 AM To: [email protected] Subject: [edk2] Dyanamic primitive creation I am trying to create dynamic primitives in a form, the calls were successful and I am able to see the one of values, but the string I am using for the question prompt are not displayed (I am dynamically setting those strings). [[Eric]] I'm not clear how your code is written, but we have an example in DriverSampleDxe, in the DriverCallback function, in the EFI_BROWSER_ACTION_FORM_OPEN case for QuestionId == 0x1234, we will insert action op code in the form, you can refer it. If still has problem, can you help to attach you code and we can find where the error is? Also I did see whenever I enters into the form, the dynamic primitives are getting appended and the list keeps growing, I am not aware of how to clear or remove the primitives from existing form. Any help? [[Eric]] we have two methods to add new op code, #1 adds new op code after the label, so every time new op code is added and old op code still there, example like the above code for question 1. #2 replaces the code between two labels, so every time only new op code shows, the old code between these two labels will be replaced. Example shows in DriverCallback function, EFI_BROWSER_ACTION_CHANGING case, when QuestionId == 0x1234.
