How can we get the children(calendardayitem) of parent object(calendarview) in winui?

To get the children of a parent object in WinUI using C++, you can use the GetChildren
method of the parent object. Here's an example:
cpp// Get a handle to the parent object (calendarView)
auto calendarView = GetHandleToCalendarView();
// Get the children (calendarDayItems) of the parent object
winrt::Windows::Foundation::Collections::IVectorView<winrt::CalendarDatePicker::CalendarDayItem> children = calendarView.GetChildren();
In this example, GetHandleToCalendarView()
is a function that returns a handle to the CalendarView
object, and winrt::CalendarDatePicker::CalendarDayItem
is the type of the children objects that we want to retrieve.
Once we have the children objects, we can iterate over them using a for
loop:
cpp// Iterate over the children objects (calendarDayItems)
for (auto&& child : children)
{
// Do something with each child object
auto date = child.Date().ToString().c_str();
OutputDebugString(date);
}
In this example, we retrieve the date property of each child object and output it to the debug console.
Note that the GetChildren
method returns an IVectorView
object, which is read-only. If you need to modify the children objects, you may need to create a new IVector
object and add the children to it.
