无法获取TextBoxes（2）来填充网格空间

2018-06-17 17:21:55

所以我相信这可能是一个简单的答案，我只是没有看到它，但经过20次谷歌搜索和3天试图独自解决问题，我投降了。下面是我使用的xaml。我需要的是两个文本框填充所有剩余空间并且大小相同。我尝试过StackPanel，DockPanel，Grid（如下图），甚至嵌套每一个并嵌套一个UniformGrid。似乎没有任何工作，我只是用MinHeight指定的任何高度得到2个文本框。将Grid.Row设置从Auto更改为*只会导致TextBoxes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="*"/>
                    <ColumnDefinition Width="Auto"/>
                </Grid.ColumnDefinitions>
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="23"/>
                    <RowDefinition Height="Auto"/>
                </Grid.RowDefinitions>
                <Label Content="Select Contact:" Height="28" Grid.Row="0" Grid.Column="0" HorizontalAlignment="Right" FontStyle="Italic" FontWeight="Bold"></Label>
                <ComboBox Grid.Column="1" Grid.Row="0" Height="23" HorizontalAlignment="Right" Width="150" ItemsSource="{Binding Source={StaticResource contactList}}" DataContext="{Binding Source={StaticResource contactList}}" Name="contactSelectionBox"></ComboBox>

                    <Label Content="Repo Pmnt" Width="Auto" Name="repoPayment" MouseLeftButtonDown="repoPayment_MouseLeftButtonDown" MouseEnter="notesLabel_MouseEnter" MouseLeave="notesLabel_MouseLeave" />
                    <Label Content="CS Xfer" Width="Auto" Name="custServ" MouseLeftButtonDown="custServ_MouseLeftButtonDown" MouseEnter="notesLabel_MouseEnter" MouseLeave="notesLabel_MouseLeave" />
                    <Label Content="Spanish" Width="Auto" Name="spanish" MouseLeftButtonDown="spanish_MouseLeftButtonDown" MouseEnter="notesLabel_MouseEnter" MouseLeave="notesLabel_MouseLeave" />
                </WrapPanel>
                <MyNamespace:WatermarkTextBox Grid.Row="2" Grid.ColumnSpan="2" Style="{StaticResource TextBox Style}" MinHeight="98" Margin="15,5,15,5" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" AcceptsReturn="True" TextWrapping="Wrap" VerticalScrollBarVisibility="Auto" Name="callTwoNotes"  TextChanged="callTwoNotes_TextChanged" FontWeight="Bold" IsEnabled="False" ClipToBounds="False"></MyNamespace:WatermarkTextBox>
                <Button Grid.Row="3" Grid.ColumnSpan="2" Height="23" Name="flipFlopButton" VerticalAlignment="Center" Width="75" Click="flipFlopButton_Click">
                        <Image Source="Images/FlipFlop.gif" />
                </Button>
                <MyNamespace:WatermarkTextBox Grid.Row="4" Grid.ColumnSpan="2" Style="{StaticResource TextBox Style}" MinHeight="98" Margin="15,5,15,5" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" AcceptsReturn="True" TextWrapping="Wrap" VerticalScrollBarVisibility="Auto" Name="callNotes"  TextChanged="callNotes_TextChanged" FontWeight="Bold"></MyNamespace:WatermarkTextBox>
            </Grid>
    </TabItem>

TextBoxes上的样式的xaml在下面，仅为了完整。

<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>

代码发布有两个问题

TextBoxes的网格RowDefintion被列为Auto而不是* 。这意味着行将根据单元格内容的大小进行调整，而不是基于网格的大小。将其更改为*因此它的大小将基于可用空间。

<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样式正在为您的项目定义Height 。这意味着它将使TextBox保持在指定的高度，而不是重新调整它的大小以适应可用空间。您可以删除此样式设置器，也可以将网格中文本框的高度设置为自动。

删除这个setter

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

或者将TextBox标签上的Height属性设置为Auto。在对象的标记中设置属性将覆盖样式属性

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

这在几分钟前被其他人回答，但现在答案已经消失。尝试删除这些行：

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

可能会覆盖Stretch

编辑：好吧，我试过你的代码，你需要改变的是你的网格RowDefinitions，试试

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

你也可能想要删除你的minheight。事实上，你应该尝试去除所有你明确的高度和宽度，让WPF照顾这一点，那是什么布局系统。
