I have this code :
var selected = from c in myList group c by c.MainTitle into n select new GroupingLayer<string, MyObject>(n);
longListSelector.ItemsSource = selected; //Error here
public class GroupingLayer<TKey, TElement> : IGrouping<TKey, TElement>
{
private readonly IGrouping<TKey, TElement> grouping;
public GroupingLayer(IGrouping<TKey, TElement> unit)
{
grouping = unit;
}
public TKey Key
{
get { return grouping.Key; }
}
public IEnumerator<TElement> GetEnumerator()
{
return grouping.GetEnumerator();
}
System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator()
{
return grouping.GetEnumerator();
}
}
What does its trying to tell me ?, how to solve this ?
I am Working on windows Phone 8 application.
It's telling you that longListSelector.ItemsSource
is of type IList
, but the value stored in selected
is an IEnumerable
, and you can't assign one to the other.
Try calling ToList()
:
var selected = (from c in myList
group c by c.MainTitle into n
select new GroupingLayer<string, MyObject>(n)).ToList();
longListSelector.ItemsSource = selected;
