Problem with retrieving data from C# .NET .DLL in NAV

(0) ShareShare
ReportReport
Posted on by Community Member

Hi everyone,

I prepared c# code where I added some data and i want to get this data in NAV. 

Everything is ok, when I only display this data in C# code (for example with MessageBox.Show), but when i'm trying to get this in C/AL (MESSAGE(data)) - something is wrong, because it does not work.

This is Control Add IN, so i added field on the page with this AddIn, and i'm trying to enter the c/al code in ControlAddIn trigger.

What is wrong? 

Code on this screen below:

DnD.png

DnD = DotNet Variable with my AddIn .dll.

Drag a File And Drop - field on the page with ControlAddInProperty - add in name + add in public token.

How can I get any datas from my dotnet dll? I need this, because I have to add some information about drag and drop files to nav tables.

Code which I want to have in NAV.

public void picbox_dnd(Object sender, DragEventArgs e)
        {

            string[] filecollection = (string[])e.Data.GetData(DataFormats.FileDrop);
            foreach (string file in filecollection)
            {
                data = Path.GetFullPath(file);
                MessageBox.Show(data);
            }

        }


Thanks for any ideas!

    Can you share you dll if you do not mind. I will try locally and tell you what exactly you want to do.

    Thanks, but for example: " this.RaiseControlAddInEvent(index, data);" does not work in new versions of NAV.

    I read this article and I don't find solution for my issue.

    Do you want maybe another ideas?

    I only need to retrieve  path of the dropped file from this DLL and add it as a text variable. Later I will use this data to upload files to BLOB.

    It's not important for me, where can I get any data from this dll, but I want to do it somewhere.

    That means when you try this alone with code unit. it works for you ? You need this on Page OnControlAddin trigger ?

    Thanks for your reply.

    I know, how to call this function, but OnControlAddIn trigger does not work.

    When i am trying to do something in this trigger, (i.e. C/AL MESSAGE('x')_ and when I'm running my page this code is not displaying. I want to use this trigger, but I can't.

    // As I guess this would be your Constructor Call

    Dnd := Dnd.DroGDrop;

    Then you need to call your method Dnd.picbox_dnd right with sending proper parameters.
