我在gridview中创建了两个Combobox列。现在我想根据第一个组合框的值填充第二个组合框(On first combobox selectedValueChanged事件)。请回复。

一般方法可能如下所示:
private MyType1 _selectedItem1;
public MyType1 SelectedItem1
{
get { return _selectedItem1; }
set
{
if (_selectedItem1 == value) return;
_selectedItem1 = value;
//replace with string implementation, if needed
OnPropertyChanged(() => SelectedItem1);
if (_selectedItem1 == ...)
{
ItemsSource2 = new List<MyClass2> { ... };
}
else if (_selectedItem1 == ...)
{
...
}
}
}
private IList<MyType2> _itemsSource2;
public IList<MyType2> ItemsSource2
{
get { return _itemsSource2; }
set
{
if (_itemsSource2 == value) return;
_itemsSource2 = value;
OnPropertyChanged(() => ItemsSource2);
}
}
