今天突然发现的问题，询问一下大佬们有遇到相关的情况没，
GridControl设置AllowInitiallyFocusedRow=false后与事件的绑定有问题了，这两去掉任意一个就正常，不能共存。

            <dxg:GridControl
                Height="300"
                AllowInitiallyFocusedRow="False"

                ItemsSource="{Binding Iv_List, Mode=OneWay}"
                SelectedItem="{Binding Iv_Info, Mode=OneWay}"
                SelectionMode="Row">
                <b:Interaction.Triggers>
                    <b:EventTrigger EventName="SelectionChanged">
