一、DataGrid分组
在Silverlight的表格中可能需要对某一些数据进行分组以方便客户查看，我们使用PagedCollectionView集合作为数据源，然后通过设置其GroupDescriptions属性值，添加需要分组的实体集合属性，注意：如果需要两层分组则添加两个属性即可。
Xaml代码：
<sdk:DataGrid HorizontalAlignment="Left" AutoGenerateColumns="False" Name="ShowCityList" VerticalAlignment="Top" Height="400" > <sdk:DataGrid.Columns> <sdk:DataGridTextColumn Header="省会" Binding="{Binding AddrName}" Width="108"/> <sdk:DataGridTextColumn Header="城市" Binding="{Binding CityName}" IsReadOnly="True" Width="108"/> <sdk:DataGridTextColumn Header="电话区号" Binding="{Binding TelNum}" IsReadOnly="True" Width="108"/> </sdk:DataGrid.Columns> </sdk:DataGrid>
Xaml.cs代码如下：
PagedCollectionView view = new PagedCollectionView(CityInfo.GetInfo()); //此处根据AddrName属性分组 view.GroupDescriptions.Add(new PropertyGroupDescription("AddrName")); //如果需要多重分组，则取消以下注释 //view.GroupDescriptions.Add(new PropertyGroupDescription("CityName")); this.ShowCityList.ItemsSource = view;
实体数据源函数如下：
public static List<CityInfo> GetInfo() { var list = new List<CityInfo>(); list.Add(new CityInfo() { AddrName = "北京", CityName = "北京市", TelNum = "010" }); list.Add(new CityInfo() { AddrName = "上海", CityName = "上海市", TelNum = "020" }); list.Add(new CityInfo() { AddrName = "广东", CityName = "广州市", TelNum = "021" }); list.Add(new CityInfo() { AddrName = "广东", CityName = "深圳市", TelNum = "0210" }); list.Add(new CityInfo() { AddrName = "四川", CityName = "成都市", TelNum = "028" }); list.Add(new CityInfo() { AddrName = "四川", CityName = "内江市", TelNum = "0832" }); list.Add(new CityInfo() { AddrName = "四川", CityName = "自贡市", TelNum = "0831" }); return list; }
效果如下：
二、模拟合并单元格
在本实例中我们通过对数据源进行构造，然后在DataGrid控件上设置DataGridTemplateColumn的模板方式模拟合并单元格。
Xaml代码：
<sdk:DataGrid HorizontalAlignment="Left" AutoGenerateColumns="False" Name="ShowCity" VerticalAlignment="Top" Height="400" Margin="400 0 0 0" > <sdk:DataGrid.Columns> <sdk:DataGridTextColumn Header="省会" Binding="{Binding AddrName}" IsReadOnly="True" Width="108"/> <sdk:DataGridTemplateColumn Header="城市" Width="108"> <sdk:DataGridTemplateColumn.CellTemplate> <DataTemplate> <ItemsControl ItemsSource="{Binding CityNames}"/> </DataTemplate> </sdk:DataGridTemplateColumn.CellTemplate> </sdk:DataGridTemplateColumn> <sdk:DataGridTemplateColumn Header="电话区号" Width="108"> <sdk:DataGridTemplateColumn.CellTemplate> <DataTemplate> <ItemsControl ItemsSource="{Binding TelNums}" /> </DataTemplate> </sdk:DataGridTemplateColumn.CellTemplate> </sdk:DataGridTemplateColumn> </sdk:DataGrid.Columns> </sdk:DataGrid>
Xaml.cs代码：
this.ShowCity.ItemsSource = CityInfo.GetInfoList();
实体数据源函数如下：
public static List<CityInfo> GetInfoList() { var list = new List<CityInfo>(); list.Add(new CityInfo() { AddrName = "北京", CityNames = new List<string>() { "北京市" }, TelNums = new List<string>() { "010" } }); list.Add(new CityInfo() { AddrName = "上海", CityNames = new List<string>() { "上海市" }, TelNums = new List<string>() { "020" } }); list.Add(new CityInfo() { AddrName = "广东", CityNames = new List<string>() { "广州市", "深圳市" }, TelNums = new List<string>() { "021","0210" } }); list.Add(new CityInfo() { AddrName = "四川", CityNames = new List<string>() { "成都市", "内江市","自贡市" }, TelNums = new List<string>() { "028","0832","0831" } }); return list; }
效果如下：
三、实体类如下：
/// <summary> /// 城市信息的实体类 /// </summary> public class CityInfo { private string _AddrName; private string _CityName; private string _TelNum; public string AddrName { get { return _AddrName; } set { _AddrName = value; } } public string CityName { get { return _CityName; } set { _CityName = value; } } public string TelNum { get { return _TelNum; } set { _TelNum = value; } } private List<string> _CityNames; public List<string> CityNames { get { return _CityNames; } set { _CityNames = value; } } private List<string> _TelNums; public List<string> TelNums { get { return _TelNums; } set { _TelNums = value; } } }
