Question

I am developing a Windows Phone App which needs draw a lot of polygons and polylines in runtime.

I have searched the google and stackoverflow found that Dispatcher.BeginInovoke() can’t satisfy my needs. Because I must create the DependencyObjects such as Polygon and Polyline in my non-UI thread. Can you help me?

Thanks in advance.

Answer 1

if you create ui element in your non-ui thread .

you must use dispather to make your ui thread execute ui action or else it will throw exception.

for example :

            ThreadHelper.RunInNewThread(() =>
            {

                Dispatcher.BeginInvoke(() => 

                         //something you want ui thread do
                    );

            }, 10);
