Is that correct to think so ?

are there rules to follow for this to appends ?

Parsing x:Name will set a Name property if it exists (setting x:Name and Name are synonomous).

Not all objects have a Name property (or RuntimeNamePropertyAttribute (sp?) pointing to a property)

However, you are trying to modify the object tree such that it will persist with an x:Name.
Since TranslateTransform3D has no RNPA pointing to a property, it can't be persisted in the way you hope.

RegisterName is used when you dynamically add an element to a tree...and it has a name. You need to call RegisterName yourself. It never sets a property on an object...

So, using XamlWriter, I know of no way to do this.

Sorry.

thank you Rob, i wanted to be sure i wasn't missing something. i'll try something else.

could you comment on the third case bellow ?

1st case :

> Parsing x:Name will set a Name property if it exists (setting x:Name and Name are synonomous).

this one easy, got it.

2nd case : an winFx app

if i put x:Name on a TranslateTransform3D it is added as a property on the code behind partial class .cs.gs

3rd case : loose xaml, ( this one i don't understand )

if i put x:Name on a TranslateTransform3D and have a storyboard targeting it ( this works).

where the x:Name is registered ?

thanks
