gui construction - Evaluation of Notebook chosen by FileNameSetter

Please consider the following:

I have created a GUI where I can choose the path of a notebook (which I need for later calculation) via

FileNameSetter[Dynamic[path1], "Open", {"Mathematica Notebook" -> {"*.nb"}}]

Now I would like Mathematica to evaluate the chosen notebook immediately after setting the path.

Has anyone an idea?

Answer

I suspect there might be an easier way to do this, but you might use a variation of this example:

Module[{nb},
Button["Find and run",(
    path1 = SystemDialogInput["FileOpen"];
    nb = NotebookOpen[path1, Visible -> False];
    SelectionMove[nb, All, Notebook];
    SelectionEvaluate[nb];

    NotebookClose[nb];
)]]

Update:

I initially couldn't get NotebookEvaluate[] To work inside a button, which led me to just use the method above, however a quick search and I found this answer by celtschk: How do I make NotebookEvaluate work inside Button? which means you can simplify the above and just have:

Button["Find and run",
    NotebookEvaluate[path1 = SystemDialogInput["FileOpen"]]
,Method -> "Queued"]
