I have re-used the TODO based example from the ItemsControl article, where we build a cool TODO list using a simple Code-behind class and, in this case, a Rarely what you want, but fortunately, we can easily declare a template that will be used to render each item. By default, if you bind a list of items to the ListBox, their ToString() method will be used to represent each item. Manually defining items for the ListBox makes for a fine first example, but most of the times, your ListBox controls will be filled with items from a data Text rendering, as you can see from the screenshot, where different colors have been used for each of the numbers.įrom the screenshot you might also notice another difference when comparing the ItemsControl to the ListBox: By default, a border is shown around theĬontrol, making it look like an actual control instead of just output. This gives us full control of the content as well as the ListBoxItem is actually a ContentControl, we can define custom content for it: įor each of the ListBoxItem's we now add a StackPanel, in which we add an Image and a TextBlock.
