Question

我写了以下风格：

<Style TargetType="Button" x:Key="ImageButton">
    <Setter Property="Width" Value="{Binding ActualHeight, RelativeSource={RelativeSource Self}}"/>
    <Setter Property="Padding" Value="0"/>
    <Setter Property="Margin" Value="5 0 5 0"/>
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="BorderBrush" Value="Transparent"/>
</Style>
<Style TargetType="Button" x:Key="AddButton" BasedOn="{StaticResource ImageButton}">
    <Setter Property="Content">
        <Setter.Value>
            <Image Source="/MyProject;component/Images/Icons/Add.png"/>
        </Setter.Value>
    </Setter>
    <Setter Property="Command" Value="{Binding AddCommand}"/>
</Style>
<Style TargetType="Button" x:Key="DeleteButton" BasedOn="{StaticResource ImageButton}">
    <Setter Property="Content">
        <Setter.Value>
            <Image Source="/MyProject;component/Images/Icons/Delete.png"/>
        </Setter.Value>
    </Setter>
    <Setter Property="Command" Value="{Binding DeleteCommand}"/>
</Style>

我通过以下方式申请：

<Button Style="{StaticResource DeleteButton}" Grid.Row="0" Grid.Column="0"/>
<Button Style="{StaticResource AddButton}" Grid.Row="0" Grid.Column="1"/>

所有这些都发生在带有不同标签的TabControl中。再次从某个选项卡更改为此选项卡后，图像将消失。当我从其他选项卡更改为此选项卡时，图像不会消失。有没有人有任何想法为什么这个出现？

更新 - 解决方案：

<DataTemplate x:Key="AddTemplate">
    <Image Source="/MyProject;component/Images/Icons/Add.png"/>
</DataTemplate>
<Style TargetType="Button" x:Key="AddButton" BasedOn="{StaticResource ImageButton}">
    <Setter Property="ContentTemplate" Value="{StaticResource AddTemplate}"/>
    <Setter Property="Command" Value="{Binding AddCommand}"/>
</Style>

我回答了类似的问题here。在您的情况下，根本原因与引用的问题相同。
