C# 从代码隐藏创建数据模板

对不起，这个问题不是很一般

我有一个ListView，我必须从代码隐藏中填充它，这个ListView还需要从代码隐藏中获取它的GridViewColumn

对于字符串，建立连接并不困难，但现在我不想在ListView中创建一个表示布尔值的椭圆

XAML中的代码相当简单，但我无法将其转换为c代码

下面是XMAL代码的一部分：

<ResourceDictionary>
    <BooleanToVisibilityConverter x:Key="BoolToVisibility" />
    <DataTemplate x:Key="templateAdmin">
        <DockPanel>
            <Ellipse Width="8" Height="8" Visibility="{Binding Path=isAdmin, Converter={StaticResource BoolToVisibility}}" Fill="Black"/>
        </DockPanel>
    </DataTemplate>
</ResourceDictionary>

<ListView>
    <ListView.View>
        <GridView>
            <GridViewColumn DisplayMemberBinding="{Binding LastName}" Header="Last Name"/>
            <GridViewColumn CellTemplate="{StaticResource templateAdmin}"
                <GridViewColumnHeader">
                    <TextBlock Text="S"/>
                </GridViewColumnHeader>
            </GridViewColumn>
        </GridView>
    </ListView.View>
</ListView>

我不认为我离。。。只是我想不出最后的步骤

缺少的行是：

var ellipseVisBinding = new Binding("isAdmin");
ellipseVisBinding.Converter = new BooleanToVisibilityConverter();

fef.SetBinding(Ellipse.VisibilityProperty, ellipseVisBinding);

（我注意到您已将模板中的DockPanel从代码版本中排除，因此我也已将其删除）

在代码隐藏？克隆中创建DockPanel真的有很好的理由吗

private void CreateGridViews()
{
    //Creating the Text was easy!
    GridViewColumns.add(new GridViewColumn(){ Header = "LastName", DisplayMemberBinding = new Binding("LastName") });

    //Creating the Ellipse was harder!
    GridViewColumn gvc = new GridViewColumn();
    DataTemplate dt = new DataTemplate();

    gvc.DisplayMemberBinding = new Binding("isAdmin");
    FrameworkElementFactory fef = new FrameworkElementFactory(typeof(Ellipse));
    fef.SetValue(Ellipse.WidthProperty, 8.0D);
    fef.SetValue(Ellipse.HeightProperty, 8.0D);
    fef.SetValue(Ellipse.FillProperty, new System.Windows.Media.SolidColorBrush(System.Windows.Media.Colors.Black));

    //I'm guessing that somewhere here there should be some binding to the visibility property and some sort of conversion done... But I can't figure out how!

    dt.VisualTree = fef;
    gvc.CellTemplate = dt;
    GridViewColumns.Add(gvc);
}

var ellipseVisBinding = new Binding("isAdmin");
ellipseVisBinding.Converter = new BooleanToVisibilityConverter();

fef.SetBinding(Ellipse.VisibilityProperty, ellipseVisBinding);
