如何使用mvvm-light触发gotfocus
使用 silverlight,我们希望将焦点移动到文本框。 如何使用 mvvm-light 触发gotfocus? 视图包含:
<TextBox Margin="4,4,0,0" Text="{Binding Path=SearchOID, Mode=TwoWay}">
<i:Interaction.Triggers>
<i:EventTrigger EventName="GotFocus">
<cmd:EventToCommand Command="{Binding GotFocusCommand, Mode=TwoWay}"/>
</i:EventTrigger>
</i:Interaction.Triggers>
</TextBox>
- ViewModel 应该是什么样子?
- 如何从 ViewModel 触发此操作?
