无法获取TextBoxes（2）填充网格空间

Question

因此，我坚信这可能是一个简单的答案，但我只是没有看到它，但是经过20次Google搜索和3天的尝试，我自己投降了。 我正在使用的xaml在下面。 我需要的是两个文本框填充所有剩余空间并保持大小相等。 我已经尝试过StackPanel，DockPanel，Grid（如下所示），甚至嵌套了其中的每一个并嵌套了UniformGrid。 似乎没有任何效果，我只得到2个文本框，它们具有为MinHeight指定的高度。 将Grid.Row设置从“自动”更改为*只会导致文本框居中并随着窗口的缩小和增长而移动。

        <TabItem Header="Notes" Name="notesTab">
            <Grid>
                <Grid.ColumnDefinitions>

                    <ColumnDefinition Width="Auto"/>

            </Grid>
    </TabItem>

出于完整性考虑，下面是TextBoxes上样式的xaml。

<Style x:Key="TextBox Style" TargetType="{x:Type MyNamespace:WatermarkTextBox}">
        <Setter Property="CharacterCasing" Value="Upper" />
        <Setter Property="HorizontalAlignment" Value="Left" />
        <Setter Property="VerticalAlignment" Value="Top" />
        <Setter Property="Height" Value="23" />
        <Setter Property="Width" Value="Auto" />
        <Setter Property="SelectAllOnGotFocus" Value="True" />
    </Style>

Answer 1

发布的代码有两个问题

RowDefintion的网格的RowDefintion列为Auto而不是* 。 这意味着将根据单元格内容的大小而不是网格的大小来确定行的大小。 将此更改为*以便其大小取决于可用空间。

<Grid.RowDefinitions>
    <RowDefinition Height="Auto"/>
    <RowDefinition Height="Auto"/>
    <RowDefinition Height="*"/>
    <RowDefinition Height="23"/>
    <RowDefinition Height="*"/>
</Grid.RowDefinitions>

另一个问题是您的TextBox样式正在为项目定义Height 。 这意味着它将文本框保持在指定的高度，而不调整其大小以适合可用空间。 您可以删除此样式设置器，也可以将“网格”中“文本框”上的“高度”设置为“自动”。

删除此二传手

<Style x:Key="TextBox Style" TargetType="{x:Type MyNamespace:WatermarkTextBox}">
    <Setter Property="Height" Value="23" />
    ...
</Style>

或将TextBox标记上的Height属性设置为Auto。 在对象的标签中设置属性会覆盖样式化的属性

<MyNamespace:WatermarkTextBox Height="Auto" Grid.Row="2" ... />
<MyNamespace:WatermarkTextBox Height="Auto" Grid.Row="4" ... />

Answer 2

几分钟前有人回答了这个问题，但现在答案消失了。 尝试删除这些行：

    <Setter Property="HorizontalAlignment" Value="Left" /> 
    <Setter Property="VerticalAlignment" Value="Top" />

可能会覆盖拉伸

Answer 3

编辑：好的，我尝试了您的代码，您需要更改的是您的Grid RowDefinitions，尝试

<Grid.RowDefinitions>
    <RowDefinition Height="Auto"/>
    <RowDefinition Height="Auto"/>
    <RowDefinition Height="2*"/>
    <RowDefinition Height="23"/>
    <RowDefinition Height="2*"/>
</Grid.RowDefinitions>

并且您可能还希望删除自己的身高。 实际上，您应该尝试删除所有显式的高度和宽度，让WPF负责，这就是布局系统的作用。
