資料來源格式：Dictionary<int, List<string>>
1.通過xaml設定
<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.通過程式碼設定
DataGridTextColumn column = new DataGridTextColumn();
column.Header = "name4";
column.Binding = new Binding("Value[3]");
dg.Columns.Add(column);

<DataGrid x:Name="dg" ItemsSource="{Binding Dic}" AutoGenerateColumns="False">

<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;
}
}
}
