可以使用与此类似的方法来完成.

it can be done with something similar to this.

例如:-

<TextBox Margin="89,116,69,123" x:Name="txtFilter" Background="AliceBlue" >
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="TextChanged">
                <cmd:EventToCommand Command="{Binding SearchedTextChanged}" CommandParameter="{Binding Text, ElementName=txtFilter}"/>
            </i:EventTrigger>
        </i:Interaction.Triggers>
    </TextBox>
