Hi,

Unfortunately, I could not replicate your issue. I tried to create a sample by following your step by step. However, it works well in here. The item collection is not 0. Perhaps, there are some settings that missing. Would you mind to replicate the issue in my sample? I need it to investigate your issue.

{

int index = e.SelectedIndex; WebListBoxItem item = WebListBox1.Items[index] as WebListBoxItem;

I am getting Index out of range error when it gets to WebListBoxItem item... line.

I should have my collection count to 4 but it only shows 0.

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
