Page is not refreshed

Cem_Karaer

Hello,

I use a dotnet variable with events. When a call comes to a client, a page in NAV 2013 should view caller's data (data are found by using caller's phone number). Dotnet variable catches the call, finds the phone number and finds the related customer writes all those to page variables which are shown as fields, but but.. I cannot display the data as soon as the call comes, but when I manually refresh the page (pressing F5 key), all of data are shown.

I could not find anyway to achieve the behavior of pressing F5 in code. Is it possible?

Note: CurrPage.UPDATE doesn't work. The page even does not show any message (MESSAGE command)!

Hi,

You have two options.
1. Option
You can use Send keys, as explained in this blog
http://dynamicsuser.net/blogs/mark_brummel/archive/2009/12/16/tip-25-update-header-page-from-the-line-page.aspx

2. Option
You can create a time add-on as explained in this blog:

I hope this helps.

I preferred the first option, because it seems fairly simple, but unfortunately the following error appeared:

OK

Hi,

Without being able to see the code it is difficult to say what is wrong.

Anyhow when I red the message it looks like you called SendKeys without any parameters, at least that is what the error message says.

I hope this helps.

The PingPong add-in was included in NAV 2013 for doing these kinds of timed callbacks.

The problem persists. Automation variables cannot be used. Instead of automation I used dotnet variable with the help of following link:

http://www.mibuso.com/forum/viewtopic.php?p=242129#p242129

Here are the patches of the code. The event is triggered when a phone call comes to the client terminal:

VoxtronClient70::OnContactTransfer(newContact : DotNet "VoxtronClient.ClientIntegration70_Contact_Interface")
CallFunction(newContact.ContactFrom);

SystemWindowsFormsSendKeys.SendWait('{F5}');
SystemWindowsFormsSendKeys.SendWait('{F5}');

Global Variable (WithEvents = Yes)
Name DataType Subtype Length
VoxtronClient70 DotNet VoxtronClient.ClientIntegration70.'VoxtronClient70, Version=1.0.0.0, Culture=neutral, PublicKeyToken=ebf42ccfc26401bd'

Local Variable (RunOnClient = Yes)
Name DataType Subtype Length
SystemWindowsFormsSendKeys DotNet System.Windows.Forms.SendKeys.'System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'

I got the following error:

Here is the question:
Why are client callbacks not supported on Microsoft Dynamics NAV Application Server?
