WPF在代码隐藏中设置DataTemplate网格大小(ResourceDictionary)

// 在XAML中定义DataTemplate
<DataTemplate x:Key="MyDataTemplate">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>
        
        <!-- 在这里添加界面元素，并设置网格的行和列 -->
        <TextBlock Grid.Row="0" Grid.Column="0" Text="姓名:"/>
        <TextBox Grid.Row="0" Grid.Column="1" Text="{Binding Name}"/>
        
        <TextBlock Grid.Row="1" Grid.Column="0" Text="年龄:"/>
        <TextBox Grid.Row="1" Grid.Column="1" Text="{Binding Age}"/>
    </Grid>
</DataTemplate>

// 在代码中使用DataTemplate
var dataTemplate = (DataTemplate)FindResource("MyDataTemplate");
var contentControl = new ContentControl();
contentControl.ContentTemplate = dataTemplate;

// 将ContentControl添加到界面中的某个容器中
