{

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.
