只需设置您的TabControl的的Horizo​​ntalAlignment和VerticalAlignment属性拉伸：

 ＆LT; D​​ockPanel中＆GT;
    ＆LT; StackPanel的DockPanel.Dock =底部方向=横向保证金=5＆GT;
        ＆LT; TextBlock的文本=你好/＆GT;
        ＆LT; TextBlock的文字=世界/＆GT;
    ＆LT; / StackPanel的＆GT;

    ＆LT;的TabControl的Horizo​​ntalAlignment =拉伸
                VerticalAlignment =拉伸＆GT;
        ＆LT; TabItem的标题=小＆GT;
            ＆LT; TextBlock的文本=只是一些小东西/＆GT;
        ＆LT; / TabItem的＆GT;
        ＆LT; TabItem的标题=做大＆GT;
            ＆LT; StackPanel的＆GT;
                ＆LT; TextBlock的文本=一条线/＆GT;
                ＆LT; TextBlock的文本=下一行/＆GT;
            ＆LT; / StackPanel的＆GT;
        ＆LT; / TabItem的＆GT;

    ＆LT; / TabControl的＆GT;
＆LT; / DockPanel中＆GT;
 

I have a simple WPF Forms app. I have a DockPanel as my root panel. The first child is a StackPanel that has some controls in it, then the second control is a TabControl. What I want, and the panel types can change all they want is for the TabControl to maintain the fill size of the window except for what the first StackPanel consumes. However no matter what I try the TabControl seems to change its size depending on whats inside it, not whats it is inside of.

<Window>
    <DockPanel>
        <StackPanel> </StackPanel>
        <TabControl> </TabControl>
    </DockPanel>
</Window>

解决方案

Just set the HorizontalAlignment and VerticalAlignment properties of your TabControl to "Stretch":

<DockPanel>
    <StackPanel DockPanel.Dock="Bottom" Orientation="Horizontal" Margin="5">
        <TextBlock Text="Hello" />
        <TextBlock Text="World" />
    </StackPanel>

    <TabControl HorizontalAlignment="Stretch" 
                VerticalAlignment="Stretch">
        <TabItem Header="Small">
            <TextBlock Text="Just Some Small Stuff" />
        </TabItem>
        <TabItem Header="Bigger">
            <StackPanel>
                <TextBlock Text="One line" />
                <TextBlock Text="The next line" />
            </StackPanel>
        </TabItem>

    </TabControl>
</DockPanel>
