DataGrid 数据绑定使用小结二(自定义列)

Silverlight中DataGrid控件提供了三种模板分别是(DataGridCheckBoxColumn,DataGridTextColumn,DataGridTemplateColumn,RowDetailsTemplates)

这里主要讲解一下DataGridTemplateColumn,RowDetailsTemplate模板的使用方法

在DataGridTemplateColumn里分别又有显示模板CellTemplate和编辑模板CellEditingTemplate.

在编辑模板中我们可以添加任意编辑控件

在RowDetailsTemplate中主要显示一些详细的内容.

数据对象

View Code

/// <summary>
    /// DataGrid自定义列
    /// </summary>
    public class BookClass2
    {
        /// <summary>
        /// 是否选择
        /// </summary>
        public bool IsSelect { get; set; }
        /// <summary>
        /// 书名
        /// </summary>
        public string Title { get; set; }
        /// <summary>
        /// 作者
        /// </summary>
        public string Author { get; set; }
        /// <summary>
        /// 发布日期
        /// </summary>
        public DateTime Time { get; set; }
        /// <summary>
        /// 作者列表
        /// </summary>
        public List<Auth> AuthorList { get; set; }

        public string Entity { get; set; }
        /// <summary>
        /// 实例化
        /// </summary>
        /// <param name="isselect">是否选择</param>
        /// <param name="title">书名</param>
        /// <param name="author">作者</param>
        public BookClass2(bool isselect, string title, string author,string entity)
        {
            IsSelect = isselect;
            Title = title;
            Author = author;
            Entity = entity;
            Time = DateTime.Now;
            AuthorList = Auth.List;
        }
    }
    /// <summary>
    /// 作者类
    /// </summary>
    public class Auth
    {
        public string AuthName { get; set; }
        public static List<Auth> List = new List<Auth>() 
            { 
                new Auth { AuthName = "tnspop" },
                new Auth { AuthName = "tnsstar" }, 
                new Auth { AuthName = "tnssun" } 
            };
    }

DataGrid数据控件

View Code

<UserControl xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"  xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"  x:Class="DataGridTest.Control.DataGridBook2"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Width="400" Height="150">
    <Grid x:Name="LayoutRoot" Background="White">
        <data:DataGrid Name="gridSetColumns" AutoGenerateColumns="False">
            <data:DataGrid.Columns>
                <data:DataGridCheckBoxColumn Header="操作" Binding="{Binding IsSelect}"/>
                <data:DataGridTextColumn Header="书名" Binding="{Binding Title}"/>
                <data:DataGridTemplateColumn Header="作者">
                    <data:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Author}"/>
                        </DataTemplate>
                    </data:DataGridTemplateColumn.CellTemplate>
                    <data:DataGridTemplateColumn.CellEditingTemplate>
                        <DataTemplate>
                            <ComboBox ItemsSource="{Binding AuthorList}">
                                <ComboBox.ItemTemplate>
                                    <DataTemplate>
                                        <TextBlock Text="{Binding AuthName}"/>
                                    </DataTemplate>
                                </ComboBox.ItemTemplate>
                            </ComboBox>
                        </DataTemplate>
                    </data:DataGridTemplateColumn.CellEditingTemplate>
                </data:DataGridTemplateColumn>
                <data:DataGridTemplateColumn Header="发布日期">
                    <data:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Time}"/>
                        </DataTemplate>
                    </data:DataGridTemplateColumn.CellTemplate>
                    <data:DataGridTemplateColumn.CellEditingTemplate>
                        <DataTemplate>
                            <controls:DatePicker SelectedDate="{Binding Time}"></controls:DatePicker>
                        </DataTemplate>
                    </data:DataGridTemplateColumn.CellEditingTemplate>
                </data:DataGridTemplateColumn>
            </data:DataGrid.Columns>
            <data:DataGrid.RowDetailsTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Entity}"/>
                </DataTemplate>
            </data:DataGrid.RowDetailsTemplate>
        </data:DataGrid>

    </Grid>
</UserControl>

后台cs代码

View Code

public partial class DataGridBook2 : UserControl
    {
        public DataGridBook2()
        {
            InitializeComponent();
            Databinding();
        }

        private void Databinding()
        {
            List<BookClass2> list = new List<BookClass2>() 
            { 
                new BookClass2(true, "坏蛋是怎样炼成的", "tnspop","这本书讲了谢文东是如何从一个弱者变成一个强者的"),
                new BookClass2(false, "咸郎平说", "tnsstar","这本书讲了一些常见的经济问题,分析的很透彻"),
                new BookClass2(true, "帝国主义在中国", "tnssun","这本书讲了那些资本投资的金融学家在中国的一些见不得光的事情") 
            };
            gridSetColumns.ItemsSource = list;
        }
    }

至此,DataGrid数据自定义列完毕,下一节将讲如何在dataGrid中操作数据对象,数据绑定模式和对象集合绑定
