Clear datagrid values in wpf

Question

I need to flush my datagrid everytime when a treeviewitem is clicked. My code is given below.

private void treeView1_SelectedItemCh         


        

Answer 1

You may consider using ObservableCollection<> class rather than IEnumerable<>.

ObservableCollection users = new ObservableCollection();
dataGrid1.ItemsSource = users;

You can clear the datagrid by using the below code.

users.Clear();
