How to select multiple items in the Windows 8 multilistpicker phone


I need to display a list of items in list picker,Im using list picker with multiple selection mode.Is there any way to check the check boxes of multiple items from c#(without user's interaction).I found many ways to find the list of selected items but couldnt find how to set multiple items as selected from code behind.Please help.I tried using

for(int i=0;i<selecteditems.count;i++)

This doesnt work ..

listpicker.SelectedItems = List<your selected items>;
