Hello abc123abc123,

I've asked for some help and advise from our devs, and we will post in this topic a bit later.

Try to use the following UI-command:

Code: Select all

pdfViewer.DoVerb("", "ExecuteCommand", "GoBack", null, PXCVA_Sync);

HTH.

It works but with some problems: I open a new Document now i scroll in this document to an other position and the i press last document i jump at the first time back to the position where i come from when i scrolled. At the second time i press the last doc button i go back to my first document.

Ok. You may try to use other way for your case (pseudocode):

Code: Select all

array_of<string> backHistory;

youreventhandler OnEvent(Type, Name, ...)
{
    if (Type == PXCVA_OnDisplayPrompt)
    {
        string srcName;
        if (Name == "Prompts.ConfirmOpenSite")
        {
            pdfViewer.GetProperty(Name + ".Name", out srcName, 0);
        }
        else if (Name == "Prompts.ConfirmLaunchFile")
        {
            pdfViewer.GetProperty(Name + ".FileName", out srcName, 0);
        }
        if (!srcName.IsEmpty())
        {
            backHistory.add(srcName);
        }
    }
}
................................................
yourform
{
    OnBackBtn()
    {
         if (!backHistory.IsEmpty())
         {
               string srcName = backHistory.GetLast();
               backHistory.RemoveLast();
               pdfViewer.OpenDocument(srcName);
         }
    }
}
