Wpf 如何使用ItemsControl分配<；DataGrid.Columns>；？

我在一个控件中有一个datagrid（这里是：DataGridSelectorControl），我想使用ItemTemplate创建它的coulmns。实际上，我想这样做：

  <DataGrid  x:Name="grd" ItemsSource="{Binding Source={StaticResource theSource}}" AutoGenerateColumns="False"  >
                <DataGrid.Columns>
                <ItemsControl ItemsSource="{Binding DataGridColumnItems}">
                    <ItemsControl.ItemsPanel>
                        <ItemsPanelTemplate>
                            <StackPanel Orientation="Horizontal" />
                        </ItemsPanelTemplate>
                    </ItemsControl.ItemsPanel>
                </ItemsControl>
                </DataGrid.Columns>
            </DataGrid>

  public static readonly DependencyProperty DataGridTextColumnItemsProperty=DependencyProperty.Register("DataTextColumnItems", typeof(ObservableCollection<DataGridColumn>), typeof(DataGridSelectorControl)))); 
    public ObservableCollection<DataGridColumn> DataGridColumnItems 
    { 
        get 
        { 
            return (ObservableCollection<DataGridColumn>)GetValue(DataGridTextColumnItemsProperty); 
        } 
        set 
        { 
            SetValue(DataGridTextColumnItemsProperty, value); 
        } 
    }

  <DataGrid  x:Name="grd" ItemsSource="{Binding Source={StaticResource theSource}}" AutoGenerateColumns="False" Columns={Binding DataGridTextColumnItems, RelativeSource={RelativeSource AncestorType=DataGridSelectorControl}}> 
            </DataGrid>

DataGrid.Columns属于ObservableCollection类型，请尝试以下操作：

  <DataGrid  x:Name="grd" ItemsSource="{Binding Source={StaticResource theSource}}" AutoGenerateColumns="False"  >
                <DataGrid.Columns>
                <ItemsControl ItemsSource="{Binding DataGridColumnItems}">
                    <ItemsControl.ItemsPanel>
                        <ItemsPanelTemplate>
                            <StackPanel Orientation="Horizontal" />
                        </ItemsPanelTemplate>
                    </ItemsControl.ItemsPanel>
                </ItemsControl>
                </DataGrid.Columns>
            </DataGrid>

  public static readonly DependencyProperty DataGridTextColumnItemsProperty=DependencyProperty.Register("DataTextColumnItems", typeof(ObservableCollection<DataGridColumn>), typeof(DataGridSelectorControl)))); 
    public ObservableCollection<DataGridColumn> DataGridColumnItems 
    { 
        get 
        { 
            return (ObservableCollection<DataGridColumn>)GetValue(DataGridTextColumnItemsProperty); 
        } 
        set 
        { 
            SetValue(DataGridTextColumnItemsProperty, value); 
        } 
    }

  <DataGrid  x:Name="grd" ItemsSource="{Binding Source={StaticResource theSource}}" AutoGenerateColumns="False" Columns={Binding DataGridTextColumnItems, RelativeSource={RelativeSource AncestorType=DataGridSelectorControl}}> 
            </DataGrid> 

public static readonly dependencProperty DataGridTextColumnItemsProperty=dependencProperty.Register（“DataTextColumnItems”、typeof（ObservableCollection）、typeof（DataGridSelectorControl））；
公共ObservableCollection DataGridColumnItems
{ 
得到
{ 
返回（ObservableCollection）GetValue（DataGridTextColumnItemsProperty）；
} 
设置
{ 
SetValue（DataGridTextColumnItemsProperty，value）；
} 
}
