Question

在与WPF斗争数小时之后，我需要你的帮助。

我已经阅读了很多不同的StackOverflows，但是，我似乎无法让我目前的情况有效，而且我不明白为什么。我选择使用网格与DockPanel形成对比，我也希望保持这种方式。根据我所读的行定义是可以的，模板网格的第二行应该自动拉伸。不幸的是它没有，因为似乎网格的最后一行不会移开。

这就是我的窗口当前的样子：

如您所见，蓝色行不在窗口底部。事实上，窗口首先不应该那么长。

这是我的Generic.xaml文件的代码片段，与该问题相关。它的工作方式是，我有一个带有自定义控件组的Skin：

<!-- Window START-->
<ControlTemplate x:Key="WindowTemplate" TargetType="{x:Type Window}">
    <Border BorderBrush="LightGray" BorderThickness="1" Background="Red" Padding="0" VerticalAlignment="Stretch">
        <Grid x:Name="WindowRoot" Margin="0" VerticalAlignment="Top" Background="Blue" MouseDown="Window_MouseDown">

            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="25"/>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="75"/>
                <ColumnDefinition Width="25"/>
            </Grid.ColumnDefinitions>
            <Grid.RowDefinitions>
                <RowDefinition Height="40" />
                <RowDefinition Height="*" />
                <RowDefinition Height="25" />
            </Grid.RowDefinitions>

            <!-- HEADER START-->

我无法解释为什么＆＃34;蓝条＆＃34;没有附在底部。尽管如此，窗户是如此之大。

Answer 1

我想你想改变这个：

 <Grid x:Name="WindowRoot" Margin="0" VerticalAlignment="Top" Background="Blue" MouseDown="Window_MouseDown">

到此：

     <Grid x:Name="WindowRoot" Margin="0" VerticalAlignment="Stretch" Background="Blue" MouseDown="Window_MouseDown">

WPF Grid Rows和ResizeGrip无法正确锚定
