set instance parameter values

[lrs579]

So I've created a tool in my plug-in to edit parameter values simultaneously.
However I've managed to make it work for type parameter, but when i set values for instance parameters, it saves the value but doesnt refresh that it is shown in the UI

Any idea where I should look into in the API? 

If you see in the screenshot, I tried to set "test" to Kommentare in my code, but I'd have to drag the drop down and select the value for Kommentare

The fact that the dropdown is showing "test" value seems to me that some elements are correctly being assigned, but for some reason, the element you are selecting is not. Can you verify that? Also, it would help if you post the code. Settings parameters values should be straightforward... Assuming Kommentare is Comments that should be as easy as : 
elem.get_Parameter(BuiltInParameter.ALL_MODEL_INSTANCE_COMMENTS).Set("test");

The text "Test" in the pulldown most likely comes from another element of it's category where the value already was filled in. It doesn't have anything to do with you're code.

In you're code try another previously unused value, and it won't show up in the pulldown. If it does the code fills it into another element.

So in the Code the parameter isn't actually set. Either a end commit is missing or something else happend.

Without some code we can only speculate.

ps. Element isn't in a group?, and if then the parameter should be set to "Values can vary by groups instances", and as this is a Text parameter that's possible.
