Question

我试图用Paging创建一个Datagrid，但我还没有那么远。现在我有了这个。

<UserControl x:Class="SampleControls.UserControls.PageFilterGrid"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:SampleControls.UserControls"
mc:Ignorable="d"
d:DesignHeight="300"
d:DesignWidth="500"
Name="Ultra">
<Grid>
    <DataGrid Name="MyGrid" AutoGenerateColumns="{Binding ElementName=Ultra, Path=AutoGenerateColumns}" ItemsSource="{Binding ElementName=Ultra, Path=MyItemsSource}" />
</Grid>

该控件的Codebehind如下所示：

public partial class PageFilterGrid : UserControl
{
    public PageFilterGrid()
    {
        InitializeComponent();

    }
    public static readonly DependencyProperty MyItemsSourceProperty = DependencyProperty.Register("MyItemsSource",
    typeof(IEnumerable), typeof(PageFilterGrid));

    public static readonly DependencyProperty GenerateColumns = DependencyProperty.Register("AutoGenerateColumns",
    typeof(bool), typeof(PageFilterGrid), new PropertyMetadata(false));

    public static readonly DependencyProperty MyUltraGrid = DependencyProperty.Register("UltraGrid",
   typeof(DataGrid), typeof(PageFilterGrid), new PropertyMetadata(new DataGrid()));

    public IEnumerable MyItemsSource
    {
        get
        {
            return (IEnumerable)GetValue(PageFilterGrid.MyItemsSourceProperty);
        }
        set
        {
            SetValue(PageFilterGrid.MyItemsSourceProperty, value);
        }
    }
    public bool AutoGenerateColumns
    {
        get
        {
            return (bool)GetValue(PageFilterGrid.GenerateColumns);
        }
        set
        {
            SetValue(PageFilterGrid.GenerateColumns, value);
        }
    }
    public DataGrid UltraGrid {
        get
        {
            return (DataGrid)GetValue(PageFilterGrid.MyUltraGrid);
        }
        set
        {
            SetValue(PageFilterGrid.MyUltraGrid, value);
        }
    }

}

我的问题是，如果我不想自动生成列，我如何指定列而不在代码后面添加它们？我想像在XAML中一样将它们添加到网格中。下面是这样的，但这不起作用。

我尝试过将这些列重新设置并设置该属性，但这似乎对XAML无效。

<controls:PageFilterGrid x:Name="myultra" AutoGenerateColumns="False" MyItemsSource="{Binding MyCollection}">
        <controls:PageFilterGrid.UltraGrid>
            <controls:PageFilterGrid.UltraGrid.Columns>
                <DataGridTextColumn Header="amount" Binding="{Binding}" />
            </controls:PageFilterGrid.UltraGrid.Columns>
        </controls:PageFilterGrid.UltraGrid>
</controls:PageFilterGrid>
