本文介绍了动态添加DataTemplate - 无法找到Converter的StaticResource的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
public void AddGridViewColumns（）
{
GridView view =（GridView）_myListView.View;
GridViewColumn column = BuildGridViewColumn（1）;
view.Columns.Add（column）;
}
public virtual GridViewColumn BuildGridViewColumn（int blockIndex）
{
string templateXaml = string.Format（
@< DataTemplate
xmlns =http://schemas.microsoft.com/winfx/2006/xaml/presentation
xmlns：x =http://schemas.microsoft.com/winfx/2006/xaml
xmlns：local =clr-namespace：Pse.MyTest; assembly = MyTest>
< DataTemplate.Resources>
< local：BlockToBrushConverter
x：Key =_ blockToBrushConverter/>
< /DataTemplate.Resources>
< TextBlock
Style ={{StaticResource _gridViewCenterItemStyle}}
Text = {{Binding Path = Block {0} .ConditionLabel}}
Foreground ={{Binding Path = Block {0}，Converter = {{StaticResource _blockToBrushConverter}}}}/>
< / DataTemplate>，
blockIndex）;
System.Diagnostics.Debug.Print（templateXaml）;
GridViewColumn column = new GridViewColumn（）;
column.Header = string.Format（Block {0}，blockIndex）;
column.CellTemplate =（DataTemplate）XamlReader.Parse（templateXaml）;
返回列;
}
Debug.Print结果为：
< DataTemplate
xmlns =http://schemas.microsoft.com/winfx/2006/xaml/presentation
xmlns：x =http://schemas.microsoft.com/winfx/2006/xaml
xmlns：local =clr-namespace：Pse.MyTest; assembly = MyTest>
< DataTemplate.Resources>
< local：BlockToBrushConverter
x：Key =_ blockToBrushConverter/>
< /DataTemplate.Resources>
< TextBlock
Style ={StaticResource _gridViewCenterItemStyle}
Text ={Binding Path = Block1.ConditionLabel}
Foreground ={Binding Path = Block1，Converter = {StaticResource _blockToBrushConverter}}/>
< / DataTemplate>
当我运行它时，它表示找不到_blockToBrushConverter。
例外是：
System.Windows.Markup.XamlParseException未处理
Message =找不到名为{_blockToBrushConverter}的资源。资源名称区分大小写。标记文件'MyTest; component / SetupWindowDictionary.xaml'中的对象'System.Windows.Data.Binding'错误行23位置13.
Source =PresentationFramework
LineNumber = 23
LinePosition = 13
NameContext =前景
如果我删除了Forecolor属性，XAML解析很好（我得到预期的结果）。看来在DateTemplate.Resources中包含转换器应该保证会被发现，但是由于某种原因，它不是。
我也尝试移动我的声明转换器资源在树中更高（到Window级别），但是也不起作用。似乎可以找到_gridViewCenterItemStyle，但由于某些原因，它拒绝找到转换器。
任何想法都非常感谢。

编辑：
问题解决：我在整个项目中进行了搜索，注意到我有一个额外的BlockToBrushConverter资源声明副本与同样的x：键入我的资源字典之一。一旦我消除了重复，问题就消失了。解决方案
为了防止别人有一天看这个问题，出来，我在这个问题的顶部提出的代码实际上是有效的。错误是我的XAML中的其他地方有以下声明：
< local：BlockToBrushConverter
x：Key = _blockToBrushConverter/>
我相信这个重复阻止了资源被本地声明为动态DataTemplate（它不能创建一个相同名称的资源在相同的上下文中两次）。
对我来说，一些未解决的问题是为什么一些StaticResources需要在本地声明，而其他像_gridViewCenterItemStyle StaticResource一样）可以在树中声明得更高（如在Window级别）没有问题。
I'm using the following code to dynamically add columns to my GridView:
public void AddGridViewColumns()
{
GridView view = (GridView)_myListView.View;
GridViewColumn column = BuildGridViewColumn(1);
view.Columns.Add(column);
}
public virtual GridViewColumn BuildGridViewColumn(int blockIndex)
{
string templateXaml = string.Format(
@"<DataTemplate
xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation""
xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml""
xmlns:local=""clr-namespace:Pse.MyTest;assembly=MyTest"">
<DataTemplate.Resources>
<local:BlockToBrushConverter
x:Key=""_blockToBrushConverter"" />
</DataTemplate.Resources>
<TextBlock
Style=""{{StaticResource _gridViewCenterItemStyle}}""
Text=""{{Binding Path=Block{0}.ConditionLabel}}""
Foreground=""{{Binding Path=Block{0}, Converter={{StaticResource _blockToBrushConverter}}}}"" />
</DataTemplate>",
blockIndex);
System.Diagnostics.Debug.Print(templateXaml);
GridViewColumn column = new GridViewColumn();
column.Header = string.Format("Block {0}", blockIndex);
column.CellTemplate = (DataTemplate)XamlReader.Parse(templateXaml);
return column;
}
The Debug.Print results in:
<DataTemplate
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:Pse.MyTest;assembly=MyTest">
<DataTemplate.Resources>
<local:BlockToBrushConverter
x:Key="_blockToBrushConverter" />
</DataTemplate.Resources>
<TextBlock
Style="{StaticResource _gridViewCenterItemStyle}"
Text="{Binding Path=Block1.ConditionLabel}"
Foreground="{Binding Path=Block1, Converter={StaticResource _blockToBrushConverter}}" />
</DataTemplate>
When I run it, it says it cannot find _blockToBrushConverter.
The exception is:
System.Windows.Markup.XamlParseException was unhandled
Message="Cannot find resource named '{_blockToBrushConverter}'. Resource names are case sensitive. Error at object 'System.Windows.Data.Binding' in markup file 'MyTest;component/SetupWindowDictionary.xaml' Line 23 Position 13."
Source="PresentationFramework"
LineNumber=23
LinePosition=13
NameContext="Foreground"
If I remove the Forecolor attribute, the XAML parses just fine (and I get the expected results). It seems like including the converter in DateTemplate.Resources should guarantee that it would be found, but for some reason it isn't.
I also tried moving the declaration for my converter resource higher in the tree (to the Window level), but that didn't work either. It seems to be able to find "_gridViewCenterItemStyle", but for some reason, it refuses to find the converter.
Any ideas greatly appreciated.
Here's the entire exception with stack trace in case it helps:
System.Windows.Markup.XamlParseException was unhandled

EDIT:
Problem solved: I did a search through my whole project and noticed I had an extra copy of the BlockToBrushConverter resource declaration with same x:Key in one of my resource dictionaries. Once I eliminated the duplication, the problem disappeared.
解决方案
Just in case someone else takes a look at this question someday, it turns out, the code I presented at the top of this question actually works. The bug was that I had the following declaration elsewhere in my XAML:
<local:BlockToBrushConverter
x:Key="_blockToBrushConverter" />
I believe this duplication prevented the resource from being declared locally for the dynamic DataTemplate (it couldn't create a resource with the same name twice within the same context).
One thing that is sort of unresolved for me is why some StaticResources need to be declared locally, while others (like the _gridViewCenterItemStyle StaticResource) can be declared higher in the tree (such as at the Window level) without a problem.
这篇关于动态添加DataTemplate - 无法找到Converter的StaticResource的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
