Hi Everyone,
Starting from Acumatica 2017 R2 you may notice a different events declaration. We call in generic events or new events declaration.
Here you can see an example for row and :
protected virtual void _(Events.FieldUpdated<DAC, DAC.field> e) {}
protected virtual void _(Events.FieldDefaulting<DAC, DAC.field> e) {}
protected virtual void _(Events.RowUpdated e) {}
protected virtual void _(Events.RowSelected e) {}
protected void _(Events.CacheAttached e) {}
From the functional side there is not difference between old and new events declarations.
However with generic events you have 2 main benifits:
- No more mistakes in names of DACs or Fields. As you rerefence it by tipe whong name won’t be even compiled.
- Don’t need to cast DACs anymore from e.Row anymore. It will have a typeinside.
PXCache cache = e.Cache; DAC row = e.Row;
However there are a couple of important things you need to know about generic events:
- Both new and old events can (but shouldn’t) be used simultaneously. I recommend you to use only one type of the events simultanoiusly. Otherwise it will be harder for you to seach for correct place of code.
- You should use only “_” name for the generic events. It will help you to not duplicate them
- If you mix new and old events – they will be collected from the Graph in the declaration sequence.
- New *ed (and RowSelecting) events will be fired in original order (ascending)
- New *ing events will be fired in reverse order (descending)
Ther are a couple of imitations also:
- CacheAttached is supported only from Acumatica 2018R1 Update 8
- Override event approach with 2 parameters isn’t yet supported. Use old events declaration with 3 parameters.
protected void _(Events.RowInserting e,PXRowInserting baseHandler)
Have a nice Development!
When we use this syntax, how to Invoke base call, before executing our customization code.
protected virtual void _(Events.FieldUpdated e)
{
InvokeBaseHandler?.Invoke(e.Cache, e);
SOLine row = e.Row as SOLine;
if (row != null)
{
}
}
Can you please advise, the below one properly coded
protected virtual void _(Events.FieldUpdated e , PXFieldUpdated InvokeBaseHandler)
{
InvokeBaseHandler?.Invoke(e.Cache, e.Args);
SOLine row = e.Row as SOLine;
if (row != null)
{
}
}
protected virtual void _(Events.FieldUpdated e, PXFieldUpdated baseHandler)
{
…
}
I want to make the grid display automatically using the Fieldupdate event and insert it inside ?
Hi Kahar, I’m not sure I got your question. Could you please bring example of what is needed?
