<textbox.behaviors>和<button.behaviors>未找到附加属性行为</button.behaviors> </textbox.behaviors>

Question

TextBox.Behavior在此属性中无效，Button.Behaviors也无法正常工作。请帮忙，我想在同一页面上创建一个列表， 因为我正在研究WP7 App：ToDO列表;

<StackPanel Orientation="Horizontal">
                        <TextBox Name="textBoxNewListName"
                             MaxLength="100"
                             Height="70"
                            Text="{Binding NewListName,Mode=TwoWay}"
                             VerticalAlignment="Top"
                             Width="400"
                             FontSize="24"
                             InputScope="Text"
                             Background="#BFFFFFFF"
                             BorderBrush="#BFFFFFFF"
                             Foreground="Black"
                             Style="{StaticResource TaskDescriptionTextBoxStyle}">
                                <TextBox.Behaviors>
       <Infrastructure:TextBoxCommand CommandBinding="   {Binding GotFocusCommand}"/>
                                </TextBox.Behaviors>
                        </TextBox>
                        <Button Name="buttonNewList"
                             Width="62"
                             HorizontalAlignment="Right"
                             BorderThickness="0"
                             Padding="0">
                                <Image Source="Images\add.png"
                                     Height="35"
                                     Width="35"/>
                                <Button.Behaviors>
  <Infrastructure:ButtonCommand CommandBinding="{Binding AddNewListCommand}"/>
                                </Button.Behaviors>
                        </Button>
                    </StackPanel>
