Event handling question

[Former Member]

Hey All,

Can someone explain to me what the InnerEvent property is and when I should use it?

I handle validate and item click events on my forms should I check this innerevent property?

What is it normally used for?

Hi Curtis,

InnerEvent is true, when the event is fired from within another event. Meaning that if you change a field on a form and through that change by example a validate is fired, the validate event has the innerEvent set to true.

In normal cases you should also check that inneEvent = false and only thant process yourcode,

Thanks Ad.

I have never really understood why this happened sometimes. Especially with the validate event. It makes a lot more sense now.

So would the general rule be to always ignore the innerevents unless you need them for something specific?

You should searching in sdk Help for clearing...

You may something like that (example in pseudoCode):

InnerEvent function()
begin

if pval.beforeaction =true  then
 select case pval.itemuid 
     case 'txtA':
             if pval.innerevent = false then 
                     *'note: innerEvent= false means a directed action of end user*                        
                      update information in txtB (for example..)
             end if 
     case 'txtB':
           if pval.innerevent =true then
                *'note: innerEvent=true means an action not directed caused by end user* 
                 ... do something
           end if

 endselect
else

endif

end

I hope help you

Hello Curtis,

InnerEvent means whether the event is fired by B1 or by user. For example, in B1, there is a mechanism that all the action will go through menu, say you click "Sales Order" in MainMenu form, but actually B1 will fire a menu click event which will open Sales Order form. So that menu click event is indicated as InnerEvent = true.

In your Add-on coding, sometimes inner event might cause problem (from pass experience), so you could filter inner event by this property.

Hope this helps,

Curtis,

In the 2005A SDK Help Center if you lookup "MenuEvent Object", there is an explanation and a sample piece of code.

HTH,
