I have a ListBox whose ItemsPanel I have replaces with a WrapPanel. The WrapPanel now hosts the databound ListboxItems. Each item has a variable sized text in it, giving each item a different width. However, I want the width to be constant so that all items have the same width as the item with the longest text. Is that possible?

Note: If you do not specify the ItemHeight and ItemWidth properties of a WrapPanel, the default height and width of child items within a WrapPanel will be the height and width of the child elements. The code snippet in Listing 1 creates a WrapPanel control and keeps its orientation to horizontal by default.
WPF - WrapPanel. The only difference between StackPanel and WrapPanel is that it doesn’t stack all the child elements in a single line; it wraps the remaining elements to another line if there is no space left. WrapPanel is mostly used for tabs or menu items. The hierarchical inheritance of WrapPanel class is as follows −.
ItemWidth specifies the size of the layout partition that is reserved by the WrapPanel for the child element. As a result, ItemWidth takes precedence over an element's own width. String representation of a Double value equal to or greater than 0.0034 but equal to or less than 160000.
In case you're unfamiliar with using a WrapPanel like this or just new to WPF it's perhaps an idea to start by explaining what an ItemsPanel is. In WPF we use an ItemsControl ( or something inheriting from it ) in order to display a collection of objects. Examples are ListBox, DataGrid, ListView and ComboBox.
Place each item in a single-row, single-column (auto width) grid, and name the column. Set Grid.IsSharedSizeScope on the ListBox and all grids will have the same width.
