Question

I m trying to bind a List to a DataGrid. Here is the code snippet:

public class Parson
{
    public string LastName { get; set; }
    public string FirstName { get; set; }

    public Parson(string lastName, string firstName)
    {
        LastName = lastName;
        FirstName = firstName;
    }
}

public class Persons : List<Parson>
{
    // Parameterless constructor      
    public Persons()
    {
    }
    public new void Add(Person parson)
    {
        base.Add(parson);
    }
}

后面的法典:

Persons persons = new Persons();
persons.Add(new Parson("New","Person");
dataGrid1.DataContext = persons;

xaml:

<my:DataGrid Name="dataGrid1" 
             xmlns:my="http://schemas.microsoft.com/wpf/2008/toolkit" 
             CanUserAddRows="True" 
             ItemsSource="{Binding}" 
             AutoGenerateColumns="False">
    <my:DataGrid.Columns>
        <my:DataGridTextColumn Header="First Name" Binding="{Binding Path=FirstName}"/>
        <my:DataGridTextColumn Header="Last Name" Binding="{Binding Path=LastName}"/>
    </my:DataGrid.Columns>
</my:DataGrid>

The result is that an empty grid is displayed! Anyone know why?

(说明:这一答案在“NET Framework v4.0”中得到证实:

简单、四部分的行动......

first, on your DataGrid control in the XAML mark-up I recommend you set AutoGenerateColumns="False" (you should be able to do this manually better than they can do it automatically)
second, on the same control set ItemsSource="{Binding}", which informs the grid it will be getting it s column and row data from a source not defined at design-time.
third, construct the columns to look how you want them to look and for each bind to the column data with something like Binding="{Binding Path=UniqueID}". Note that the value after Path is interpolated so mind things like case-sensitivity. For the List<> you are targetting the value will presumably be one of the property-names from objects in your target List<>. Rinse and repeat as many times as needed for each column in your DataGrid.
fourth, in your form code-behind, within the constructor or during form load or wherever it best suits your needs, set the DataContext of your grid. This should take a form similar to {gridControlName}.DataContext = {target-List<>}

说明项目内容而不是数据内容,删除<代码> 页: 1 这可能是徒劳的。

Edit:

我刚刚检查了一些代码,写道采用了相同的数据控制(WPF工具kit),事实上,我确实制定了项目资源,而不是数据内容。如果需要一个例子,让我知道。

在你的数据中:

ItemsSource="{Binding Path=.}"

这对我来说是 worked的。
