Hi all,
I have a RadListBox in my aspx page, and it has many items (more than 50). So I set the Height property of the RadListBox for not breaking the page design (I set it to 150px). And the scroll bar appears. An item which will not be seen if the user doesn't scroll the scroll bar of the RadListBox to the bottom is set as checked (for example, the 48th item is selected). If now I click a button to make the page postback. The selected item will then be set unchecked, which is not what I expected. But if I set the 3rd item as checked (This item will be shown even if the user doesn't scroll the scroll bar), the item checked before is still be checked after postback, and this is correct.
If I scroll to the bottom and manually check the 48th item, the 48th item will still be checked after postback, and this is also correct.
Is this a bug of the RadListBox? Or am I missing something?
Thanks in advance.
