OnPreNewElement parentId is always 0

[stao]

Hi everyone,

for some weird reason the parentId ( from Info.get(2) )
is always 0.
What i want to do is to check the parent elements stereotype.
here is my code:

public bool EA_OnPreNewElement(EA.Repository Repository, EA.EventProperties Info)
        {
int parentId = (int)((long)((EA.EventPropertyClass)Info.Get(1)).Value);
            System.Windows.Forms.MessageBox.Show(Info.Get(2).Value.ToString());

thx for your time.

Do a search, there was a topic on it recently...

I already did but didnt find anything useful..
My only Problem is that EA.EventProperties Info doesnt seem to carry the parentId although it should to as it can be found in the EA Help.
I guess i make a mistake with the typecasting.

Just to make sure there is no confusion - the ParentID is not the ID of the Package (in case that's what you were expecting).  The parentId returned in the EventProperties for the EA_OnPreNewElement event will only contain a value if the new element is the child of another element.

Also, in your code example you are assigning the value of Info.Get(1) to your parentId variable instead of Info.Get(2), and your casting seems a little strange.  Should this be as follows?

Code: [Select]

int parentId = (int)((EA.EventProperty)info.Get(2)).Value;

yeah i see
thx both of you.
i solved the problem by checking the parents Stereotype in the onPostNewElement Method and delete the element if the parent is not correct.
Do you see a "smarter" way i can solve this?
I have 2 Stereotypes ( SDM_Object, SDM_Activity )
for my Addin SDM_Objects should only be created as sub Elements of SDM_Activity.
