I have an event assigned to events of the RadTreeView with the following statements:
Dynamically, every ~30 seconds, the RadTreeView gets a clear command:
and after the clear command is repopulated with ~ 100-150 radtreeviewitems.
Ever since I've added this to my silverlight project, I've experienced a memory leak of around 1-3MB every 30 seconds when this occurs. What do I need to manually unhook/remove to avoid the memory leak?
Thanks in advance!
Tom
Edit: removing the control fixes the leak problem.
Also: 1-3MB is not constant - it varies and sometimes looks like it is negative but if graphed, is a slow rise of memory usage.
| Me.RadTreeView1.[AddHandler](Telerik.Windows.Controls.RadTreeViewItem.SelectedEvent, New RoutedEventHandler(AddressOf OnMenuItemClicked)) |
| Me.RadTreeView1.[AddHandler](Telerik.Windows.Controls.RadTreeViewItem.CheckedEvent, New RoutedEventHandler(AddressOf OnCheckedChanged)) |
| Me.RadTreeView1.[AddHandler](Telerik.Windows.Controls.RadTreeViewItem.UncheckedEvent, New RoutedEventHandler(AddressOf OnCheckedChanged)) |
Dynamically, every ~30 seconds, the RadTreeView gets a clear command:
| RadTreeView1.Items.Clear() |

Hi Thomas Kroll,
Unfortunately this is a problem in the Silverlight runtime. Microsoft is aware of it and it will be fixed with SL4.

I also encounter this problem.
I have a Radwindow containing a Hierarchical treeview that is automatically expanded.
There is a checkbox on each level.
Every time the radwindow is opened, and the ItemsSource of the treeview is set I see the memory leak.
Is there any creative workaround to get some sort of control (not the treeview) that would allow to do this ?

Nicolas

Hello NS,
This is a video of how we demonstrate the unmanaged memory leak:

We cannot be certain that your case is identical. If you suspect that there is a memory leak and you can send us a sample project, we will be happy to investigate it.
