I have a collection of objects which I want to display as a list. So, I'm binding a LongListSelector with this collection. All the items in the collection appear in the form of list. The next thing I want to do is when the user make long press on an item so it will popup a little windows with delete,add and another options.
How i should do it? i search in a lot of places and didn't find nothing about LongListSelector and context menu
If you want a context menu... take a look at the ContextMenu control in the Phone Toolkit.
Then for an example on how to add this, look in the toolkit itself, but more specific for your question, you can have a look at a similar question here...
In short, you just add the context menu xaml on each data item of your longlistselector
