i have an

C#

ObservableCollection<T>

, it has two properties String Item and String Priority.
i want my LongListSelector to display the items with Priority "High" first then "Low" respectively.
i have tried this but it seem like a stupid idea but i am not that good a programmer yet i am intermediate.

C#

this.List.ItemsSource = this.Items.OrderBy(c => c.Priority == "High");

thank you for your contribution.

If you want to sort data in ascending order, use:

C#

this.List.ItemsSource = this.Items.OrderBy(c => c.Priority);

For descending order, use:

C#

this.List.ItemsSource = this.Items.OrderByDescending(c => c.Priority);

That's all ;)

Note: The order of items in a list will not change. You need to implement it.

5ed. Collection is done observable for notifications and for binding.
