从样式模板设置 columnDefinition 和 RowDefinition？

Question

是否可以添加以下代码：

<Grid.RowDefinitions>
    <RowDefinition Height="auto"/>
    <RowDefinition Height="*"/>
    <RowDefinition Height="auto"/>
</Grid.RowDefinitions>

到Style / Setter 模板为Grid？然后像这样自动设置RowDefinitions 为Grid？

<Grid style="{StaticResource MyRowDefs}">
    <Button  Grid.Row="0" Content="Button1/>
    <TextBox Grid.Row="1"/>
    <Button  Grid.Row="2" Content="Button2/>
</Grid>

这样做可以解决您的问题：How to create reusable WPF grid layout

对于您的示例，您可以执行以下操作：

<Window x:Class="ReUseGridTest.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:ReUseGridTest"
    mc:Ignorable="d"
    Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <Style x:Key="GridItemsStyle" TargetType="ItemsControl">
            <Setter Property="ItemsPanel">
                <Setter.Value>
                    <ItemsPanelTemplate>
                        <Grid>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="Auto" />
                                <RowDefinition Height="*" />
                                <RowDefinition Height="Auto" />
                            </Grid.RowDefinitions>
                        </Grid>
                    </ItemsPanelTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>
    <ItemsControl Style="{StaticResource GridItemsStyle}">
        <Button Grid.Row="0" Content="Button1"/>
        <TextBox Grid.Row="1" Text="Test"/>
        <Button  Grid.Row="2" Content="Button2"/>
    </ItemsControl>
</Window>

Answer 2

您不能在Style 中设置RowDefinitions 属性，因为它不是依赖属性，但您可以创建自定义Grid 类型并使用该类型：

public class CustomGrid : Grid
{
    public CustomGrid()
    {
        RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
        RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Star) };
        RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
    }
}

用法：

<local:CustomGrid>
    <Button  Grid.Row="0" Content="Button1/>
    <TextBox Grid.Row="1"/>
    <Button  Grid.Row="2" Content="Button2/>
</local:CustomGrid>
