Description
Describe the bug
The carousel control crashes when it has no items initially and one adds items afterwards.
To Reproduce
- Add a carousel without any initial items
- Add an item (e.g. via code) once the view has been initialised.
- Crashes with an Out-of-bounds exception
Expected behavior
No crash.
Additional context
Debugging shows that Carousel.UpdateItemsPosition() is crashing once it tries to use the PageIndex, which is -1 at that point and therefore of course out-of-bounds.
Possible fix is to update the PageIndex to an in-bounds range value when an item is added.
private void UpdateItemsPosition()
{
if (!CheckNull() || !_appliedTemplate || Items.Count == 0)
return;
if (PageIndex == -1) // Fixes the crash
{
PageIndex = 0;
}
