我将如何编程访问此WPF XAML资源？

 ＆LT; Grid.Resources＆GT;
＆LT;风格X：关键=lineDataPointStyle的TargetType =chartingToolkit：LineDataPoint＆GT;
                        ＆LT; setter属性=背景VALUE =深绿/＆GT;
                        ＆LT; setter属性=IsTabStopVALUE =FALSE/＆GT;
                        ＆LT; setter属性=模板值={X：空}/＆GT;
                    ＆LT; /样式和GT;
＆LT; /Grid.Resources>
 

和这里就是我想从访问的code。请注意，我需要以编程方式创建行：

  //新Assoicated图系列
                VAR供LineSeries =新供LineSeries（）;
                lineSeries.ItemsSource = newSeriesCollection;
                lineSeries.IndependentValuePath =二;
                lineSeries.DependentValuePath =KB;
                lineSeries.Title = kvp.Key;
                lineSeries.DataPointStyle =（风格）this.Resources [lineDataPointStyle]; // **不工作
 

解决方案

我不知道的路径，你是指在你的XAML网格的;然而，考虑到本XAML：

 ＆LT;窗​​口x：类=WpfApplication1.Window1
    的xmlns =htt​​p://schemas.microsoft.com/winfx/2006/xaml/$p$psentation
    的xmlns：X =htt​​p://schemas.microsoft.com/winfx/2006/xaml
    的xmlns：SRC =CLR的命名空间：WpfApplication1
    标题=测试中的应用 -  ListView的高度=300宽度=300＆GT;
    ＆LT; Window.Resources＆GT;
        ＆LT; SRC：OrderStateConverter X：关键=orderStateConverter/＆GT;
        ＆LT; D​​ataTemplate中X：关键=复选框＆GT;
            ＆LT;复选框器isChecked ={结合的XPath = @国，转换器= {的StaticResource orderStateConverter}}
                  保证金=0,1,1,1＆GT;
            ＆LT; /复选框＆GT;
        ＆LT; / DataTemplate中＆GT;
        ＆LT; D​​ataTemplate中X：关键=headerButton＆GT;
            ＆LT;按钮/＆GT;
        ＆LT; / DataTemplate中＆GT;
    ＆LT; /Window.Resources>
    ＆LT; StackPanel的＆GT;
        ＆LT; ListView的高度=自动
                  NAME =ListView1的
                  WIDTH =自动
                  的ItemsSource ={绑定源= {的StaticResource myXmlDatabase}，XPath的=项目}＆GT;
            ＆LT; ListView.Resources＆GT;
                ＆LT; D​​ataTemplate中X：关键=checkbox2＆GT;
                    ＆LT;复选框器isChecked ={结合的XPath = @国，转换器= {的StaticResource orderStateConverter}}
                  保证金=0,1,1,1＆GT;
                    ＆LT; /复选框＆GT;
                ＆LT; / DataTemplate中＆GT;
            ＆LT; /ListView.Resources>
        ＆LT; / ListView控件＆GT;
    ＆LT; / StackPanel的＆GT;
＆LT; /窗＆GT;
 

和以下code将拉动资源无论从Wndow，并在ListView：

 公共无效的someMethod（）{
        对象RES1 = this.Resources [复选框];
        对象RES2 = this.listView1.Resources [checkbox2];
        返回;
    }
 

在这种情况下，该方法是在隐藏类窗口code

how would I access this WPF XAML resource programmatically?

<Grid.Resources>
<Style x:Key="lineDataPointStyle" TargetType="chartingToolkit:LineDataPoint">
                        <Setter Property="Background" Value="DarkGreen"/>
                        <Setter Property="IsTabStop" Value="False"/>
                        <Setter Property="Template" Value="{x:Null}"/>
                    </Style>
</Grid.Resources>

and here's the code where I want to access it from. Note I need to programmatically create the lines:

 // New Assoicated Graph Series
                var lineSeries = new LineSeries();
                lineSeries.ItemsSource = newSeriesCollection;
                lineSeries.IndependentValuePath = "Second";
                lineSeries.DependentValuePath = "Kb";
                lineSeries.Title = kvp.Key;
                lineSeries.DataPointStyle = (Style) this.Resources["lineDataPointStyle"];  // ** DOES NOT WORK

解决方案

I am not sure of the path to the Grid you refer to in your xaml; however, given this xaml:

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:src="clr-namespace:WpfApplication1"
    Title="Test Application - ListView" Height="300" Width="300">
    <Window.Resources>
        <src:OrderStateConverter x:Key="orderStateConverter"/>
        <DataTemplate x:Key="checkbox">
            <CheckBox IsChecked="{Binding XPath=@State, Converter={StaticResource orderStateConverter}}" 
                  Margin="0,1,1,1" >
            </CheckBox>
        </DataTemplate>
        <DataTemplate x:Key="headerButton">
            <Button/>
        </DataTemplate>
    </Window.Resources>
    <StackPanel>
        <ListView Height="Auto" 
                  Name="listView1" 
                  Width="Auto" 
                  ItemsSource="{Binding Source={StaticResource myXmlDatabase},XPath=Item}">
            <ListView.Resources>
                <DataTemplate x:Key="checkbox2">
                    <CheckBox IsChecked="{Binding XPath=@State, Converter={StaticResource orderStateConverter}}" 
                  Margin="0,1,1,1" >
                    </CheckBox>
                </DataTemplate>
            </ListView.Resources>
        </ListView>
    </StackPanel>
</Window>

and the following code will pull the resource from both the Wndow, and the ListView:

    public void SomeMethod() {
        Object res1 = this.Resources["checkbox"];
        Object res2 = this.listView1.Resources["checkbox2"];
        return;
    }

In this case the method is in the window code behind class
