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?
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.
