Hi,

I customized the Schedule ActivityDialog, and also created a header template (see below). That worked. Now my problem ist, that i tried to bin the header caption to a class property. This seems not to work. Could you explain me what the easiest way is for changing the Dialog Caption?

Thanks kind regards Daniel
