XAML 中网格内的网格

Question

我想在 parentGrid 的第二列中有一个 childGrid（在 childGrid 中我想有两列：第一列用于标签，第二列用于文本框）

我怎么能做这样的事情？我尝试了以下代码：

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Height="*"/>
        <ColumnDefinition Height="*"/>
        <RowDefinition Height="*"/>
        <RowDefinition Height="*"/>
    </Grid.ColumnDefinitions>
    <Grid Grid.Column=1>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Height="*"/>
            <ColumnDefinition Height="*"/>
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
    </Grid>
</Grid>

Answer 1

根据您的代码，稍作修正：

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition />
        <ColumnDefinition  />
    </Grid.ColumnDefinitions>
    <Grid Grid.Column="1">
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
    </Grid>
</Grid>

注意ColumnDefinition 没有高度 - 它们有宽度。您还需要分别定义 ColumnDefinitions 和 RowDefinitions - 您将它们混合在外部网格中。我从外部网格中删除了 RowDefinitions，因为您似乎没有使用它们。您的内部网格有两列和四行。

您可能会发现这很有用。尝试使用 Kaxaml 将其粘贴到页面中，并使用外部 Grid 中对象的各种参数。我发现使用 Kaxaml 进行原型设计和试验 XAML 布局必不可少。

<Grid>  
  <Grid.ColumnDefinitions>
    <ColumnDefinition Width="Auto"/>
    <ColumnDefinition Width="Auto"/>
  </Grid.ColumnDefinitions>
  <Grid.RowDefinitions>
    <RowDefinition/>
    <RowDefinition/>
    <RowDefinition/>
  </Grid.RowDefinitions>

  <!-- 
     When I'm composing grids in XAML, I group things together by type, not by where
     they live in the grid.  This turns out to make a lot of maintenance tasks
     easier.

     Also, since Grid.Row and Grid.Column default to 0, a lot of people (and tools)
     omit them if that's their value.  Not me.  It lets me quickly check to make
     sure that content is where I think it is, just by looking at how it's organized
     in the XAML.
  -->

  <TextBlock Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" Background="Lavender" Padding="10" HorizontalAlignment="Stretch">Here's the first row of the outer grid.</TextBlock>
  <TextBlock Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="2" Background="Lavender" Padding="10" HorizontalAlignment="Stretch">Here's the third row of the outer grid.</TextBlock>

  <TextBlock Grid.Row="1" Grid.Column="0" Background="AliceBlue" Padding="10">Here's the first column of the second row.</TextBlock>

  <Grid Grid.Row="1" Grid.Column="1">
    <Grid.ColumnDefinitions>
      <!--
         This part's pretty important.  Setting up the SharedSizeGroups for these
         two columns keeps the labels and text boxes neatly arranged irrespective of
         their length.
      -->
      <ColumnDefinition SharedSizeGroup="Label"/>
      <ColumnDefinition SharedSizeGroup="TextBox"/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
      <RowDefinition/>
      <RowDefinition/>
      <RowDefinition/>
    </Grid.RowDefinitions>

    <Label Grid.Row="0" Grid.Column="0">First label</Label>
    <Label Grid.Row="1" Grid.Column="0">Second label</Label>
    <Label Grid.Row="2" Grid.Column="0">Third label, containing unusually long content</Label>

    <TextBox Grid.Row="0" Grid.Column="1">First text box, containing unusually long content</TextBox>
    <TextBox Grid.Row="1" Grid.Column="1">Second text box</TextBox>
    <TextBox Grid.Row="2" Grid.Column="1">Third text box</TextBox>

  </Grid>

</Grid>

如何在子网格中放置控件可能会有点混乱。这是一个例子。

我们有 3 * 3 的网格。然后将中心单元格进一步分为 3 行，每行都有一个按钮。

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="*"/>
        <RowDefinition Height="*"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <Grid Grid.Row="1" Grid.Column="1">
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
            <Button Grid.Row="0" Content="Button1"/>
            <Button Grid.Row="1" Content="Button2"/>
            <Button Grid.Row="2" Content="Button3"/>
    </Grid>
</Grid>

Phenevo，我今年做了很多 XAML UI 设计。试试这个，您可以轻松地将代码迁移到 Window 或 UserControl。我对网格和面板进行了颜色编码，以便您可以实时确认它们的布局——当您满意时，将背景参数吹走。

<UserControl

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    mc:Ignorable="d"
    x:Class="UatControlLibrary.sampleChilGrid"
    x:Name="UserControl"
    MinWidth="400"
    MinHeight="300"
    Width="auto"
    Height="auto">
    <Grid
        x:Name="LayoutRoot">
        <Grid
            x:Name="parentGrid"
            Width="auto"
            Height="auto"
            Background="Red">
            <Grid.ColumnDefinitions>
                <ColumnDefinition
                    Width="1*" />
                <ColumnDefinition
                    Width="1*" />
            </Grid.ColumnDefinitions>
            <Grid
                x:Name="chilGrid"
                Width="auto"
                Height="auto"
                Background="Black"
                Grid.Column="1"
                Grid.Row="0">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition
                        Width="1*" />
                    <ColumnDefinition

                    x:Name="stkpnlLabels"
                    Background="White"
                    Grid.Column="0"
                    Grid.Row="0" />
                <StackPanel
                    x:Name="stkpnlTextboxes"
                    Background="Blue"
                    Grid.Column="1"
                    Grid.Row="0" />
