Access to MDG tagged values in addin

[GrahamL]

Hi
My MDG has several tagged values defined for various elements for example "Desc".
These show up in a model containing one of these elements under a tab in the properties named after my MDG.
So far so good
I now need to access these in an addin but dont seem to be able to find a way in order to set them.

How can I do this?

They are in EA.Element.TaggedValues
Nothing really special about them.

What is the exact issue?

Here is an extract from my addin

                        EA.Element e = selectedPackage.Elements.AddNew("Context", "GSNProfile::Context");
                        EA.TaggedValue t = e.TaggedValues.AddNew("ID", "string");
                        t.Value = "xx";
                        t.Update();
                        e.Update();
                        selectedPackage.Update();
This does add a 'normal' tagged value for ID
However my MDG also has a tagged value called ID that appears in a separate tab on the properties window. It is this value that I want to set

Well, you just added a new one. Find the existing and update that.

Indeed. The tagged values that belong to the stereotype are added automatically.
You might need to update() your element first though. (and possibly even reload it, I'm not sure)

No updates needed. Just loop through the existing tagged values and find the one named ID. With that TV (you got via GetAt) set the Value (or Notes if it's a memo) and Update it. That should update the right one.

Note that you should have only MDG-defined TVs. A mix with "normal" TVs created manually calls for trouble.

Code: [Select]

                        EA.Element e = selectedPackage.Elements.AddNew("Context", "GSNProfile::Context");
                        EA.TaggedValue t = e.TaggedValues.AddNew("ID", "string");
                        t.Value = "xx";
                        t.Update();
                        e.Update();
                        selectedPackage.Update();

You may end up with issues with this code (or code similar to it) because it adds tagged values to the element before it is saved. I suspect because it's a profile element it may save it in the background, but I wouldn't be comfortable relying on that.

The Update call on the package seems to be unnecessary.
