I have two identical ComboBoxes. One is inside of a gallery and the other is inside of a data card. The one inside of a data card works perfectly. For the one inside the gallery, it appears that selecting an item from the box does not change its boxName.Selected value. Whenever I loop over the gallery's items (via ForAll(galleryName.AllItems)), the ComboBox in the gallery is always treated as if nothing has been selected. No other control in the gallery has this issue. Only the ComboBox.
The only difference in code between the two ComboBoxes is their DefaultSeletedItem field, but that shouldn't be relevant because this issue happens even when I manually select an item.
So, do ComboBoxes have their Selected property behave differently inside galleries? I'd post the code, but I want to know if this is already a known feature.
