WPF数据网格选择已禁用

List<MyClass> 简单类的列表:

public class MyClass
{        
    public string String1 { get; set; }
    public string String2 { get; set; }

    public MyClass(string string1, string string2)
    {
        String1 = string1;
        String2 = string2;
    }
}

此列表显示在WPF中 DataGrid 在代码隐藏中:

首先添加列:

List<DataGridColumn> cols = ParentClass.GetColumns();
foreach (DataGridColumn dgc in cols)
{
    myDataGrid.Columns.Add(dgc);
}

myDataGrid.ItemsSource = ParentClass.MyClassess;

从某种意义上说,这可以很好地工作,因为DG会被填充,但不可能在DataGrid中选择一行并 DataGrid.SelectedItem 总是返回null。DataGrid注册鼠标事件,但每次单击都不会选择任何行,就像DataGrid被禁用一样。。。

SelectionMode="Single"  
SelectionUnit="FullRow" 
IsReadOnly="False"

以下是所需的XAML:

<TabItem Header="Sessions" GotFocus="TabSessionsGotFocus">
                    <Grid>
                        <Grid.RowDefinitions>                            
                            <RowDefinition Height="*"></RowDefinition>                            
                        </Grid.RowDefinitions>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition></ColumnDefinition>
                            <ColumnDefinition></ColumnDefinition>
                            <ColumnDefinition></ColumnDefinition>
                        </Grid.ColumnDefinitions>

                        <DockPanel Grid.Row="0" Grid.ColumnSpan="3" Margin="0">
                            <DataGrid x:Name="dgSessions" DockPanel.Dock="Top" IsEnabled="True" AutoGenerateColumns="False" 
                                SelectionMode="Single"  SelectionUnit="FullRow" Background="WhiteSmoke" 
                                AlternatingRowBackground="Gainsboro" GridLinesVisibility="None" IsReadOnly="False"
                                ColumnHeaderHeight="25" RowHeight="21" MouseRightButtonDown="SessionsRightButtonDown" >
                                <DataGrid.ContextMenu>
                                    <ContextMenu x:Name="cmSessions">
                                        <MenuItem x:Name="miSessionActions">
                                            Action
                                        </MenuItem>                                        
                                    </ContextMenu>
                                </DataGrid.ContextMenu>
                            </DataGrid>
                        </DockPanel>
                    </Grid>
                </TabItem>
