我在WPF中有一个带有自动生成列的DataGrid .

如何禁用MVVM模式之后的所有行的排序功能？

<DataGrid AutoGenerateColumns="True" 
            ItemsSource="{Binding MyList}" 
</DataGrid>

我有一个带有DataTable的DataGrid和ItemsSource.列数随时间而不同.如果列的DataType属于类AI,则希望使用DataTemplate来自定义单元格内容的外观.

我已经设定

AutoGenerateColumns="True" 

在DataGrid上,以便生成DataTable中的所有列.

如果DataType是A类型,我用DataGridTemplateColumn替换DataGridColumn

private void DataGrid_AutoGeneratingColumn(object sender, system.Windows.Controls.DataGridAutoGeneratingColumnEventArgs e)
{
    if (e.PropertyType == typeof(A))
    {
        e.Column = new DataGridTemplateColumn
        {
            CellTemplate = (DataTemplate)Resources["ATemplate"],
            Header = e.Column.Header,
            HeaderTemplate = e.Column.HeaderTemplate,
            HeaderStringFormat = e.Column.HeaderStringFormat
        };
    }
}

DataTemplate看起来像这样.

<DataTemplate x:Key="ATemplate">
   <RadioButton Content="{Binding Name}" GroupName="{Binding GroupName}" IsChecked="{Binding IsSelected}" />
</DataTemplate>

显示了radiobutton,但我得到了所有属性的绑定错误,例如

BindingExpression path error: 'IsSelected' property not found on 'object' ''DataRowView'

A类看起来像这样

public class A
{
    public string Name { get; set; }
    public string GroupName { get; set; }
    public …

我有一个服务,我希望能够根据控制反转原理创建,所以我创建了一个接口和一个服务类.

public interface IMyService
{
    void DoSomeThing1();
    void DoSomeThing2();
    void DoSomeThing3();
    string GetSomething();

}

public class MyService : IMyService
{
    int _initialValue;
    //...

    public MyService(int initialValue)
    {
        _initialValue = initialValue;
    }

    public void DoSomeThing1()
    {
        //Do something with _initialValue
        //...
    }

    public void DoSomeThing2()
    {
        //Do something with _initialValue
        //...
    }

    public void DoSomeThing3()
    {
        //Do something with _initialValue
        //...
    }

    public string GetSomething()
    {
        //Get something with _initialValue
        //...
    }
}

以Unity为例,我可以设置IoC.

public static class MyServiceIoc
{
    public static …
