How to get selected objects in ObjectListView

Question

I get properly selected object in TreeListView when reading SelectedObjects, however it fails when items are selected with shift key. In this case I get empty lists for SelectedObjects and SelectedIndices and SelectedIndex returns -1.

Display is showing proper selection.

I've tried traversing through all objects in tree and checking with IsSelected, but I get empty list as well.

Once I add with ctrl click some extra item I get proper selection again.

How can I get proper selection in this case? How can I disable shift selects otherwise?

Using ObjectListView 2.8.1

正如Rev1.0所指出的，这是一个错误的事件处理程序的问题。回复SelectionChanged会给出正确的结果。我没有在文档中找到它。

使用SelectedIndexChanged而不是SelectionChanged的原因是，在我的情况下，表单由另一个应用程序托管，该应用程序不会引发Application.Idle事件。但是，可以使用CanUseApplicationIdle属性轻松修复此问题。这是一个很好的控制。
