Question

我是新手，所以请耐心等待。

我现在有Style。将其粘贴到窗口中以查看其实际效果。

<Window.Resources>

<Style x:Key="SelectionButton3"
        TargetType="{x:Type Button}">

    <Setter Property="Template">
        <Setter.Value>

                        <ColumnDefinition Width="55" />
                    </Grid.ColumnDefinitions>

                    <Border x:Name="TheBorder"
                            BorderThickness="0,1.5,1.5,1.5"
                            CornerRadius="3"
                            Background="SteelBlue"
                            Height="35"
                            Grid.Column="1"
                            Grid.Row="0"

                                Grid.Column="0">

                        <Rectangle.LayoutTransform>
                            <RotateTransform Angle="-45" />
                        </Rectangle.LayoutTransform>

                        <Rectangle.BitmapEffect>
                            <DropShadowBitmapEffect ShadowDepth="5" />
                        </Rectangle.BitmapEffect>

                    </Rectangle>

                    <ContentPresenter x:Name="ContentArea"
                                       VerticalAlignment="Center"
                                       HorizontalAlignment="Center"
                                       Content="{Binding Path=Content, RelativeSource={RelativeSource TemplatedParent}}" />
                </Grid>

                <ControlTemplate.Triggers>
                    <Trigger Property="IsMouseOver"
                                Value="True">
                        <Setter TargetName="TheBorder"
                                Property="BitmapEffect">
                            <Setter.Value>
                                <DropShadowBitmapEffect ShadowDepth="0" />
                            </Setter.Value>
                        </Setter>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>

    </Setter>

    <Setter Property="Foreground"
            Value="White"/>
    <Setter Property="FontFamily"
            Value="Segoe UI" />
    <Setter Property="FontSize"
            Value="20" />

    </Style>

<Grid.ColumnDefinitions>

    <ColumnDefinition Width="250" />
</Grid.ColumnDefinitions>

<Button Grid.Row="1"
        Grid.Column="1"
        Style="{StaticResource SelectionButton3}"
        Margin="0,0,0,5"
        Click="Button_Click">

               Margin="32.5,0,0,0"
               Source="/app;component/Media/Images/Mail/email.png" />

        <TextBlock Text="Email"
                   Grid.Column="1"
                   HorizontalAlignment="Center"
                   VerticalAlignment="Center"
                   Margin="22,0,0,0"/>

    </Grid>


</Button>

我有两个问题：

1）为什么只出现部分文字？

2）如何将Image和TextBlock放入Template并绑定到它们？

Answer 1

剪切文本的原因是您没有为ContentPresenter指定Grid.Row和Grid.Column。这会导致您的按钮内容默认为ControlTemplate上的第0行和第0列，这与您的边距和位置相结合会导致按钮元素上的Textblock被截断。我猜这可能是你的意图？

<ContentPresenter x:Name="ContentArea"
   Grid.Column="0"
   Grid.ColumnSpan="2"
   Grid.Row="0"
   VerticalAlignment="Stretch"
   HorizontalAlignment="Stretch"
   Content="{Binding Path=Content, 
             RelativeSource={RelativeSourceTemplatedParent}}" />

现在ContentPresenter将跨越ControlTemplate网格上的两列，因此您的Textblock将有更多空间展示自己。

回答您的第二个问题How do I put the Image and Textblock in the template and just bind to them?

一种方法是将Button类子类化，例如将其称为MyImageButton，并在此新实现两个名为Image和Text的新依赖项属性类。然后，您可以将<Image>和<TextBlock>移动到控制模板中，并将其绑定到新的Image和Text属性。然后，您可以实例化MyImageButton并使用新属性设置按钮的图像和文本。
