Question

我的WPF主窗体如下图 ，有5行1列，然后三个按钮，我要实现点击其中一个按钮动态加载控件

<Window x:Class="LQ.MES.BurnSyetem.MainWindow"

        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition></ColumnDefinition>

        <Menu Grid.Row="0" Grid.Column="0" Margin="0,0,0.2,1.4">
            <MenuItem Name="menuConfig" Header="系统参数配置" Click="menuConfig_Click" Height="31"/>
            <MenuItem Name="menuFlashRunner" Header="小黑盒烧录" Click="menuFlashRunner_Click"/>
            <MenuItem Name="FlashRunner" Header="FlashRunner烧录" Click="FlashRunner_Click"/>
        </Menu>
    </Grid>
</Window>

 //主窗体第一行内再加载一个10列的Grid
            Grid msggrid = new Grid();
            msggrid.Name = "Msggrid";
            msggrid.ColumnDefinitions.Add(new ColumnDefinition());
            msggrid.ColumnDefinitions.Add(new ColumnDefinition());
            msggrid.ColumnDefinitions.Add(new ColumnDefinition());
            msggrid.ColumnDefinitions.Add(new ColumnDefinition());
            msggrid.ColumnDefinitions.Add(new ColumnDefinition());
            msggrid.ColumnDefinitions.Add(new ColumnDefinition());
            msggrid.ColumnDefinitions.Add(new ColumnDefinition());
            msggrid.ColumnDefinitions.Add(new ColumnDefinition());
            msggrid.ColumnDefinitions.Add(new ColumnDefinition());
            msggrid.ColumnDefinitions.Add(new ColumnDefinition());
            msggrid.ShowGridLines = true;

            //Button，开始暂停按钮          
            Button btnsta = new Button();
            btnsta.Content = "开始";
            btnsta.Name = "btnSta";
            var btnend = new Button();
            btnend.Content = "结束";
            btnend.Name = "btnend";

            //创建一个StackPanel用于存放Button开始暂停按钮  
            var wrappanel = new StackPanel();
            wrappanel.Orientation = Orientation.Horizontal;
            wrappanel.Children.Add(btnsta);
            wrappanel.Children.Add(btnend);

            //存放开始暂停按钮的GroupBox
            var functiongroup = new GroupBox();
            functiongroup.Header = "运行";
            functiongroup.HorizontalAlignment = HorizontalAlignment.Stretch;
            functiongroup.VerticalAlignment = VerticalAlignment.Stretch;
            functiongroup.BorderBrush = Brushes.Gray;
            functiongroup.Padding = new Thickness(50);
            functiongroup.BorderThickness = new Thickness(3);
            functiongroup.Content = wrappanel;

            //存放基础信息的GroupBox
            var basicinformationgroup = new GroupBox();
            basicinformationgroup.Header = "基础信息";
            basicinformationgroup.HorizontalAlignment = HorizontalAlignment.Stretch;
            basicinformationgroup.BorderBrush = Brushes.Gray;
            basicinformationgroup.Padding = new Thickness(50);
            basicinformationgroup.BorderThickness = new Thickness(3);

            //将msggrid放到主窗体Grid的第一行
            Grid.SetRow(msggrid, 1);
            Grid.SetColumn(msggrid, 0);
            GridControl.Children.Add(msggrid);

            //将存放开始暂停按钮的GroupBox放到msggrid里面
            Grid.SetRow(functiongroup, 0);
            Grid.SetColumn(functiongroup, 0);
            Grid.SetColumnSpan(functiongroup, 2);
            msggrid.Children.Add(functiongroup);

            //将存放基础信息按钮的GroupBox放到msggrid里面
            Grid.SetRow(basicinformationgroup, 1);
            Grid.SetColumn(basicinformationgroup, 3);
            Grid.SetColumnSpan(basicinformationgroup, 7);
            msggrid.Children.Add(basicinformationgroup);

但是我把对应GroupBox的Content换成Header他就能正常的显示在Header这个地方

我想要达到的结果就是我的Button控件能正常显示到GroupBox的Content

在后台代码中添加数据模型:

public class Author

{

public int ID { get; set; }

public string Name { get; set; }

public DateTime DOB { get; set; }

public string BookTitle { get; set; }

public bool IsMVP { get; set; }

public string Email { get; set; }

public string City { get; set; }

public string Country { get; set; }

public int Zip { get; set; }

}

窗口页面的后台代码:

namespace wpf_DataGird_Test

{

///

/// MainWindow.xaml 的交互逻辑

///

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

dg.ItemsSource = CreateDemoSource();

}

//

private void dg_LoadingRow(object sender, DataGridRowEventArgs e)

{

e.Row.Header = (e.Row.GetIndex() + 1).ToString();

}

//创建数据源

private List CreateDemoSource()

{

List authors = new List();

authors.Add(new Author()

{

ID = 101,

Name = “Mahesh Chand”,

BookTitle = “Graphics Programming with GDI+”,

DOB = new DateTime(1975, 2, 23),

IsMVP = false

});

authors.Add(new Author()

{

ID = 201,

Name = “Mike Gold”,

BookTitle = “Programming C#”,

DOB = new DateTime(1982, 4, 12),

IsMVP = true

});

authors.Add(new Author()

{

ID = 244,

Name = “Mathew Cochran”,

BookTitle = “LINQ in Vista”,

DOB = new DateTime(1985, 9, 11),

IsMVP = true

});

return authors;

}

}

}
