转换的ControlTemplate XAML到C＃ [英] Converting ControlTemplate XAML to C#

问题描述

我一直难倒，试图将下面的代码转换成纯C＃。此XAML代码是如何使任何东西圆角Cavanaghs博客。代码工作，但我需要将其转换为C＃，因为我需要它是动态的在某些情况下。如果你能帮助将是巨大的。

I have been stumped with trying to convert the following code into pure c#. This XAML code is from Cavanaghs blog on how to make rounded corners on anything. The code works but I need to convert it to c# as i need it to be dynamic in some cases. If you could help that would be great.

<Setter Property="Template">
<Setter.Value>
    <ControlTemplate TargetType='{x:Type ListViewItem}'>
        <Grid>
            <Border CornerRadius="15" Name="mask" Background="White"/>
            <StackPanel Background="Beige">
                <StackPanel.OpacityMask>
                    <VisualBrush Visual="{Binding ElementName=mask}"/>
                </StackPanel.OpacityMask>
                <GridViewRowPresenter Content="{TemplateBinding Content}" Columns="{TemplateBinding GridView.ColumnCollection}"/>
                <TextBlock Background="LightBlue" Text="{Binding News}" />
            </StackPanel>
        </Grid>
    </ControlTemplate>
</Setter.Value>

到目前为止，我有以下。但我正在逐渐错误

So far I have the following but I am getting errors.

FrameworkElementFactory border = new FrameworkElementFactory(typeof(Border));
border.SetValue(Border.BackgroundProperty, Brushes.White);
border.SetValue(Border.CornerRadiusProperty, new CornerRadius(8, 8, 8, 8));
border.SetValue(Border.NameProperty, "roundedMask");

据我可以告诉我不能做的VisualBrush作为FrameworkElementFactory（崩溃），但如果我声明它作为一个经常性元素的VisualBrush我不能在传递边界作为视觉因为它的一个FrameworkElementFactory。

As far as I can tell I cant make the VisualBrush as a FrameworkElementFactory (crashes), but if i declare it as a regular element VisualBrush i cant pass border in as a Visual since its a FrameworkElementFactory.

只要我得到失去，任何帮助，将不胜感激。
感谢您的帮助。

Simply i am getting lost, any help would be appreciated. Thanks for any help

推荐答案

您不想知道这一点。说真的，你不这样做，这是一个噩梦。

You do not want to know this. Seriously, you don't, it's a nightmare.

编辑：如果我没有犯任何错误，这是你的代码的翻译。 ..

If i did not make any mistake this is the translation of your code...

Setter setter = new Setter();
setter.Property = ListViewItem.TemplateProperty;
ControlTemplate template = new ControlTemplate(typeof(ListViewItem));
var grid = new FrameworkElementFactory(typeof(Grid));
var border = new FrameworkElementFactory(typeof(Border));
border.SetValue(Border.BackgroundProperty, Brushes.White);
border.SetValue(Border.NameProperty, "mask");
border.SetValue(Border.CornerRadiusProperty, new CornerRadius(15));
grid.AppendChild(border);
var stackPanel = new FrameworkElementFactory(typeof(StackPanel));
stackPanel.SetValue(StackPanel.BackgroundProperty, Brushes.Beige);
var visualBrush = new FrameworkElementFactory(typeof(VisualBrush));
visualBrush.SetBinding(VisualBrush.VisualProperty, new Binding() { ElementName = "mask" });
stackPanel.SetValue(StackPanel.OpacityMaskProperty, visualBrush);
var gridViewRowPresenter = new FrameworkElementFactory(typeof(GridViewRowPresenter));
gridViewRowPresenter.SetValue(GridViewRowPresenter.ContentProperty, new TemplateBindingExtension(GridViewRowPresenter.ContentProperty));
gridViewRowPresenter.SetValue(GridViewRowPresenter.ColumnsProperty, new TemplateBindingExtension(GridView.ColumnCollectionProperty));
stackPanel.AppendChild(gridViewRowPresenter);
var textBlock = new FrameworkElementFactory(typeof(TextBlock));
textBlock.SetValue(TextBlock.BackgroundProperty, Brushes.LightBlue);
textBlock.SetBinding(TextBlock.TextProperty, new Binding("News"));
stackPanel.AppendChild(textBlock);
grid.AppendChild(stackPanel);
template.VisualTree = grid;
setter.Value = template;

编辑：那里仍留有一个bug，在的VisualBrush 不能这样被创建，其余的似乎工作。

There is still a bug left, the VisualBrush cannot be created like that, the rest seems to work.
