I have a simple LongListSelector from wp7 toolkit. Now I want to disable opening popup when anybody taps on the group header. How to reach that ?
Just don't specify the <GroupItemTemplate> element in your LongListSelector and this will disable the fullscreen jump list.
A LongListSelector shows fullscreen. Why would a popup ever happen? If for some reason stuff is being done behind the screens have a boolean set to true everytime the user taps on the longlistselector and only show the popup if that boolean is false
