Question

我有一个像以下一样的Windows Phone应用程序。文本框中有两个按钮。当用户点击“beyazbtn”时，我希望它被折叠并且“saribtn”被折叠为可见。我可以创建两个处理这两个按钮的click的事件处理程序，但是当我尝试使另一个按钮崩溃时，我意识到我无法访问C＃代码中的beyazbtn或saribtn变量。我该如何访问它们？

    <Style x:Key="ButtonStyle1" TargetType="Button">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="31*"/>
                            <RowDefinition Height="21*"/>
                        </Grid.RowDefinitions>
                        <es:RegularPolygon Fill="#FFF4F4F5" InnerRadius="0.47211" PointCount="5" Stretch="Fill" Stroke="Black" UseLayoutRounding="False" Grid.RowSpan="2"/>
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Margin="0,11,0,10" Grid.RowSpan="2"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>

在Loaded的{{1}}中添加Grid个事件。然后保存按钮参考。
