与其对这个问题投反对票，不如回答告诉我出了什么问题！

我想在自定义控件的标签中设置按钮内容，因为当我使用它时，内容属性不可见并且按钮为空（无文本）。

Nocturno，谢谢，我是这个网站的新手，我把 C[space]sharp，但我的名声不允许我使用新标签，所以我删除了这个。

我想把Button.Content属性放在自定义控件的一个标签里，因为模板替换了原来的按钮设计，我用这个来节省代码，添加这个按钮不需要很多代码。

            </Trigger>
        </ControlTemplate.Triggers>
    </ControlTemplate>
</Button.Template>

该按钮是基于 Adob​​e CS5 套件上的对话框形式，因为代码很多。

您需要将 UserControls DataContext 设置为 RelativeSource=(RelativeSource Self}

<Button x:Class="WpfApplication1.UserControl1"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         mc:Ignorable="d" DataContext="{Binding RelativeSource={RelativeSource Self}}"
         d:DesignHeight="35" d:DesignWidth="273" Content="Button">

然后您需要将标签的绑定更改为：

<Label FontWeight="Normal" Content="{Binding Path=Content}" Foreground="White" HorizontalContentAlignment="Center" Name="tblckStep1Desc" Padding="0"   VerticalContentAlignment="Center">
    <Label.Effect>
        <DropShadowEffect BlurRadius="2" Color="Black" Direction="330" Opacity="0.7" ShadowDepth="1.5" />
    </Label.Effect>
</Label>

这将给出如下所示的结果：
