WPF: Dictionary<int, List<string>> in DataGrid
提问by for-each
I have a Dictionary<int, List<string>>. Each ID(int) has a corresponding dynamic list of names(List<string>).
我有一个Dictionary<int, List<string>>. 每个 ID(int) 都有一个对应的动态名称列表 ( List<string>)。
This is the expected output in Datagrid.
这是 Datagrid 中的预期输出。
ID | Name | Name | Name

<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>
if Name is not a fixed data, you need add column dynamicly like this:
如果 Name 不是固定数据，则需要像这样动态添加列：
DataGridTextColumn column = new DataGridTextColumn();
column.Header = "name4";
column.Binding = new Binding("Value[3]");
dg.Columns.Add(column);
all right ,here is my code:
好的，这是我的代码：
<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;
}
}
}
but i'd like you finish it by yourself
但我希望你自己完成

Have you tried to bind to the Valuescollection of the dictionary? Set the dictionary.Valuescollection as the ItemsSourceand turn on AutoGenerateColumns=True
您是否尝试过绑定到Values字典的集合？将dictionary.Values集合设置为ItemsSource并打开AutoGenerateColumns=True
