TabControl中宽度相等的选项卡

Question

我在选项卡控件的顶部有4个选项卡.我希望每个标签使用TabControl宽度的25%.

使用XAML这样做的正确方法是什么？

这是我尝试过的:

<Grid  HorizontalAlignment="Left" Height="458" Margin="10,65,0,0" VerticalAlignment="Top" Width="276">
    <TabControl Grid.IsSharedSizeScope="True" HorizontalAlignment="Stretch">
        <TabItem Header="Cameras">
            <Grid Background="#FFE5E5E5">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto" SharedSizeGroup="tabControl"/>
                </Grid.ColumnDefinitions>
            </Grid>
        </TabItem>
        <TabItem Header="MultiCam">
            <Grid Background="#FFE5E5E5">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto" SharedSizeGroup="tabControl"/>
                </Grid.ColumnDefinitions>
            </Grid>
        </TabItem>
        <TabItem Header="Search">
            <Grid Background="#FFE5E5E5">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto" SharedSizeGroup="tabControl"/>
                </Grid.ColumnDefinitions>
            </Grid>
        </TabItem>
        <TabItem Header="Admin" Margin="-2,-2,-10,-1">
            <Grid Background="#FFE5E5E5">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto" SharedSizeGroup="tabControl"/>
                </Grid.ColumnDefinitions>
            </Grid>
        </TabItem>
    </TabControl>
</Grid>

Answer 1

这是另一个技巧,Grid可以重叠任意数量的元素:

<Grid>
    <UniformGrid Columns="4" Margin="5,0">
        <FrameworkElement x:Name="c1"/>
        <!-- no need to add the other three -->
    </UniformGrid>
    <TabControl>
        <TabItem Header="header" Width="{Binding ElementName=c1, Path=ActualWidth}"/>
        <TabItem Header="header" Width="{Binding ElementName=c1, Path=ActualWidth}"/>
        <TabItem Header="header" Width="{Binding ElementName=c1, Path=ActualWidth}"/>
        <TabItem Header="header" Width="{Binding ElementName=c1, Path=ActualWidth}"/>
    </TabControl>
</Grid>

a UniformGrid的大小与TabControl用于测量每列的宽度相同.只添加一个,FrameworkElement因为所有TabItems都是相同的大小.
