Remove Extra Space around Listbox

Question

I have some extra space around my Listbox. It\'s 1px wide, but I don\'t know where it comes from...

Answer 1

This is the default control template for ListBox:

Notice the Padding="1" on Border named Bd. Since this is harcoded and not template bound, you can either retemplate the ListBox and set the padding to 0, or since Padding on the ScollViewer has a TemplateBinding to the Padding of the ListBox, you can set the Padding on your ListBox to -1 to offset the padding on the border.
