问题描述
提出一个单独的问题,与对
Making a separate question, related to comments on the answer to WPF 4: What happened to DataGridColumnHeader?
似乎我可以在UserControl中使用DataGridHeaderBorder,可以在ResourceDictionary中独立使用,但不能在模板的样式设置器中使用。 / p>
It appears I can use DataGridHeaderBorder in a UserControl, stand-alone in a ResourceDictionary, but not in a Style's setter of a Template.
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
>
<!-- Works -->
<DataTemplate x:Key="yomama">
<DataGridColumnHeader />
</DataTemplate>
<!-- Compile Error: error MC3074: The tag 'DataGridHeaderBorder' does not exist in XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'. -->
<Style x:Key="{x:Type DataGridRowHeader}"
TargetType="{x:Type DataGridRowHeader}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridRowHeader}">
<Grid>
<DataGridHeaderBorder></DataGridHeaderBorder>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
如果我使用xmlns:dg = http://schemas.microsoft .com / wpf / 2008 / toolkit,即使我在项目中没有引用WPFToolkit。我已验证自己已设置为.NET4,并引用了PresentationFramework v4。
I can get it to work if I use xmlns:dg="http://schemas.microsoft.com/wpf/2008/toolkit", even though I'm not referencing WPFToolkit in the project. I've verified I'm set to .NET4 and referencing PresentationFramework v4.
感谢您帮助我删除dg:hack。
Thanks for helping me remove the dg: hack.
