Question

我在我的一个用户控件中使用Infragistics TabGroupPane。我使用MVVM进行绑定。当我在另一个usercontrol中使用此usercontrol时，我想为Infragistics ContentPane设置DataTemplate。我怎么能这样做？

以下是我正在使用的代码，但它不起作用：

<UserControl.Resources>        
    <DataTemplate DataType="{x:Type infragistics:ContentPane}">
        <DataGrid 
        ItemsSource="{Binding Content, PresentationTraceSources.TraceLevel=High}" IsReadOnly="True" HeadersVisibility="Column" SelectionUnit="FullRow" AutoGeneratingColumn="DataGrid_AutoGeneratingColumn_1" 
            CanUserReorderColumns="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGrid}}, Path=DataContext.IsReorderSupported}"  
            CanUserSortColumns="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGrid}}, Path=DataContext.IsColSortable}"/>
    </DataTemplate>

    <DataTemplate DataType="{x:Type infragistics:PaneHeaderPresenter}">
        <DataGrid 
        ItemsSource="{Binding Content, PresentationTraceSources.TraceLevel=High}" IsReadOnly="True" HeadersVisibility="Column" SelectionUnit="FullRow" AutoGeneratingColumn="DataGrid_AutoGeneratingColumn_1" 
            CanUserReorderColumns="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGrid}}, Path=DataContext.IsReorderSupported}"  
            CanUserSortColumns="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGrid}}, Path=DataContext.IsColSortable}"/>
    </DataTemplate>
</UserControl.Resources>

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>

    <ContentControl Name="someContent" Content="{Binding InfraTabs}" Visibility="Collapsed"/>

</Grid>

注意：InfraTabs是ContentPane的集合。

谢谢，

我仍在寻找答案，但我找到了解决此问题的方法：

替代方法：我创建了一个虚拟的InfraTabViewModel，并将ContentPane的内容分配给该ViewModel。在我看来，我为InfraTabViewModel添加了一个数据窗口，它可以工作！以下是变通方法代码：在视图中：

        <DataTemplate DataType="{x:Type vm:InfraTabViewModel}">
        <DataGrid 
        ItemsSource="{Binding DGView, PresentationTraceSources.TraceLevel=High}" IsReadOnly="True" HeadersVisibility="Column" 
            SelectionUnit="FullRow" AutoGeneratingColumn="DataGrid_AutoGeneratingColumn_1" 
            CanUserReorderColumns="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGrid}}, Path=DataContext.IsReorderSupported}"  
            CanUserSortColumns="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGrid}}, Path=DataContext.IsColSortable}"/>
    </DataTemplate>

在ViewModel中：

    public class InfraTabViewModel
{
    public object DGView { get; set; }
}

public class MyViewModel
{
    ObservableCollection<ContentPane> InfraTabs = new ObservableCollection<ContentPane>();

    public ObservableCollection<ContentPane> InfraTabs
    {
        get;
        set;
    }

    public MyViewModel()
    {
        DataTable dt=new DataTable();
        //Code to populate the dataTable

        ContentPane cp = new ContentPane();
        cp.Header = "Some DataGrid";
        cp.Content = dt.AsDataView(); // does not work.
        cp.Content = new InfraTabViewModel { DGView = dt.AsDataView() }; // works.
    }
}

为Infragistics ContentPane设置datatemplate
