ListBox Items Limit

[David]

Is there a maximum limit to the number of items that can be added to the ListBox?
How can this limit be changed?

Hi David,

 
Could you explain why do you need to limit the items in the RadListBox control? The control support virtualization by default and it could work with a lot of items. In theory, the maximum number of items is limited only by the memory.

We need to display more than 1000 items (each item contains a CheckBox and TextBlock). The RadListBox does not display all the items we load. A co-worker had mention to me that there's a limit of 1000 items per his earlier contact with Telerik.

Hello David,

As George mentioned RadListBox control has a built-in virtualization and adding a thousand items in the ItemsSource shouldn't lead to any unexpected behaviors.

If you have any other questions do not hesitate to contact us again.
