In wpf how to access window.resources in usercontrol
提问by Ash
I have a child usercontrol and I am having trouble accessing its parent usercontrol's resources. The resource is a collectionViewSource and its source is set in the code behind of the parent usercontrol, the source is set to a query result from LINQ to SQL. Both usercontrols are defined in their own xaml file. I tried using DynamicResource and it complained saying it needs to be used with a DepenednecyProperty or so...
我有一个子用户控件，但无法访问其父用户控件的资源。资源是一个collectionViewSource，它的来源设置在父用户控件后面的代码中，来源设置为LINQ to SQL的查询结果。两个用户控件都在它们自己的 xaml 文件中定义。我尝试使用 DynamicResource 并且它抱怨说它需要与 DepenednecyProperty 一起使用......
parent usercontrol:
父用户控件：
...
<UserControl.Resources>
<CollectionViewSource x:Key="UsageTypeSource"/>
</UserControl.Resources>
...
child usercontrol:
子用户控件：
...
<ComboBox Height="28" HorizontalAlignment="Left" Margin="147,1,0,0" x:Name="cbxUsage"
Grid.Column="1" Grid.Row="2" Width="186"
SelectedItem="{Binding Path=UsageType, ValidatesOnExceptions=true, NotifyOnValidationError=true}"
VerticalAlignment="Top" SelectedValuePath="ID"
SelectedValue="{Binding Path=Usage}"
ItemsSource="{Binding Source={StaticResource UsageTypeSource}}"
DisplayMemberPath="Type"/>
...
The error I am getting is 'The resource "UsageTypeSource" could not be resolved'
我得到的错误是“无法解析资源“UsageTypeSource””
Can you provide the proper way to access the resource
