阅读更多关于 could the SelectionChanged event in WPF be handled only for user interaction?

I would like to handled SelectionChanged event in WPF DataGrid element for user interaction/selection only and skip if it's due to binding or other set values. Any idea how I will determine if the Selection is changed by user interaction? Or any alternate event that would do similar task? Maybe try combine SelectionChanged event with PreviewMouseDown event.

ComboBox- SelectionChanged event has old value, not new value

阅读更多关于 ComboBox- SelectionChanged event has old value, not new value

C#, .NET 4.0, VS2010. New to WPF. I have a ComboBox on my MainWindow. I hooked the SelectionChanged event of said combo box.
