I use a ListBox in a C#, WPF project. It works. Then I Tried to give the ListBox Items a individual Background. I failed. Now I make a TextBlock first, give them a individual Background and then I put it into the ListBox. It works fine but my problem is that every single line in the Listbox have their own width. I would like have that every ListBox Item has the same largest width. I tried to ask for the width when i created the TextBlock but at this time the width=NaN and the actualWidth=0.

I tried to read all ListBox Items widths with a Button Click Event and it worked.

What do i have to do so that I can do it in the same function as I filled the ListBox?

I would like that every Listbox has the same largest width.
At this Point each ListBox Item has its own width depending on the text.

  There are better ways of colouring items in a ListBox than setting the Background of TextBlocks. What did you try?

  As @mm8 said, there are better ways than the one you are currently trying. What are you actually trying? Are you trying to give each item a unique background color or are you trying to change the color when something in particular happens?
