How to know in code if a QString value is = "" or nothing?
@if (MyQStringName == ""){
}@
but that doen't work.

Did you try the documentation of [[doc:QString]]? It has many interesting methods, including one called isEmpty() that sounds about right...

You are doing an assignment <code>=</code>, not a comparison <code>==</code>.

Again, do not post your questions in the QnA Testing Area. If you have a general question, like this one, post it the General and Desktop.

Andre's response is certainly complete.
One additional remark to your code fragment. You have an assignment '=' and not '==' in your if statement. Therefore, your if statement, when used as typed in your post, cannot work.
