I am using a GridView to display real-time data (syslog messages) and it works fine as long as I keep adding records. However when I try to remove old records, the GridView just freezes (stops responding). Is there a special way to delete records? Right now I have bounds the ItemsSource to an ObservableCollection and when the number of records in it reaches 10,000 I want to delete the first 100 records (i.e index 0 through 99). GridView seems to have no problem dealing with the 10,000 records but as soon as I delete even one record, it stops responding. I have already tried my own variation of your AddRangeObservableCollection (modified it to stop CollectionChanged notification, delete 100 records and then re-start the CollectioChanged notifications) but the GridView still stops responding after deletion. Please help.

Hello, A couple questions
IF a user clicks on a tile to maximize it. Would it be possible to call a event before to maximized.
The code would be something like:
private Tile_Click()
If Tile(1) is Clicked
{
messagebox.show
If ok
{
then Tile(1) is Maximized
else
messagebox cancel
message "you don't want to max this tile
}
I know the code not even close
But and snippet would be great
Thoughts>?

Hi,
I am using the rad tree view without data binding, and am hooking into the checked changed event of the tree to alter my object model with the new selection in the background code. The checked changed event fires for every sub-node of a node in the tree to update its status, is there an event that fires after all of the checked events have completed on the tree?
Thanks for any help in advance.

Students field has Student ID, StudentFN, StudentLN while Subjects has SubjectID, Subject, Professor, StudentID.
I have associated the two student id.
My .xaml.cs is
public partial class MainWindow : Window { ObservableCollection<MyObject> _MyObject = new ObservableCollection<MyObject>(); DataContextDataContext context1 = new DataContextDataContext(); public MainWindow() { InitializeComponent(); DataContext = new ObservableCollection<MyObject>(); RadGridView1.Filtered+=new EventHandler<GridViewFilteredEventArgs>(RadGridView1_Filtered); foreach (var p in context1.Students) { _MyObject.Add(new MyObject { ID = p.StudentID, Name = p.StudentFN }); } } void RadGridView1_Filtered(object sender, GridViewFilteredEventArgs e) { RadGridView1.ItemsSource = _MyObject; } private void Button_Click(object sender, RoutedEventArgs e) { } } public class MyObject { public int ID { get; set; } public string Name { get; set; } }I tried running the gridview but it doesn't show the level 2 data grid for the each record nor the column headers of the subject table.
