数据源格式：Dictionary<int, List<string>>

1.通过xaml设置

<DataGrid x:Name="dg" ItemsSource="{Binding Dic}" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="id" Binding="{Binding Key}"/>
<DataGridTextColumn Header="Name" Binding="{Binding Value[0]}"/>
<DataGridTextColumn Header="Name" Binding="{Binding Value[1]}"/>
<DataGridTextColumn Header="Name" Binding="{Binding Value[2]}"/>
</DataGrid.Columns>
</DataGrid>

1  <DataGrid x:Name="dg" ItemsSource="{Binding Dic}" AutoGenerateColumns="False">
2             <DataGrid.Columns>
3                 <DataGridTextColumn Header="id" Binding="{Binding Key}"/>
4                 <DataGridTextColumn Header="Name" Binding="{Binding Value[0]}"/>
5                 <DataGridTextColumn Header="Name" Binding="{Binding Value[1]}"/>
6                 <DataGridTextColumn Header="Name" Binding="{Binding Value[2]}"/>
7             </DataGrid.Columns>
8         </DataGrid>

 2.通过代码设置

DataGridTextColumn column = new DataGridTextColumn();
column.Header = "name4";
column.Binding = new Binding("Value[3]");
dg.Columns.Add(column);

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41

<DataGrid x:Name="dg" ItemsSource="{Binding Dic}" AutoGenerateColumns="False">     <DataGrid.Columns>       <DataGridTextColumn Header="id" Binding="{Binding Key}"/>     </DataGrid.Columns> </DataGrid>      private Dictionary<int, List<string>> dic;    public Dictionary<int, List<string>> Dic  {      get { return dic; }      set { dic = value; }  }    public MainWindow()  {      InitializeComponent();      this.DataContext = this;      Dic = new Dictionary<int, List<string>>();      Dic.Add(1, new List<string> { "a", "b", "c", "5" });      Dic.Add(2, new List<string> { "d" });      Dic.Add(3, new List<string> { "e", "f" });        int count = 0;      foreach (List<string> lst in Dic.Values)      {          if (lst.Count > count)          {                for (int i = count; i < lst.Count; i++)              {                  DataGridTextColumn column = new DataGridTextColumn();                  column.Header = "name" + i;                  column.Binding = new Binding(string.Format("Value[{0}]", i));                  dg.Columns.Add(column);              }              count = lst.Count;          }      }  }
