Navision 2009 Addin queries (Send and receiving the data)

abhishekpareek

Hi everyone,

I have few queries related to navision 2009 addins i.e,

1) Whether it is possible to send the data from navision 2009 sp1 by using addin to third party control. I want to send the data in loop. I want to send the field name and field values one by one before initializing the controls through addins.

2) After calling the controls , I want to send back the data in string format, through addin only. Data is more then 1024 hence it means that I have to send it loop and then I nedd to add at the navision end.

Whether two points mention below are achievable?

Thanks for help in advance!

Bind the add-in to a BigText variable, then you don't have to cope with multiple roundtrips.

Whether Big Text variable can support more then 1024 size. Actually , I would be having large amount of data to be sent accross.

BigText can easily hold more than 1024 bytes - and unless you are looking at several MB's of data that would be my preferred way.

Second option would be to use the event - meaning that the control would call the event on the service tier and ask for data, incrementing a counter to ask for data. Note that every event here is a roundtrip between server and client and is executed on the main UI thread, thus blocking the UI:

Third option would be for your control to spawn up a worker thread connecting to Web Services and fetching data on the side - not blocking the UI at all - this is however a bit more complicated.

It would be great if you can give one example about how to send the data in chunks to control addin events.
I am very new to this addin thing and very less help is available for this data sending and receiving part.
