以编程方式定义StackPanel资源？

Question

I'm just poking around some WPF samples I found online, and came across an odd behaviour which I have simplified it below:

  <StackPanel Name="sp1">
    <StackPanel.Resources>
      <!--<src:ItemsForSale x:Key="MyData"/>-->
    </StackPanel.Resources>
    <ListView Name="itemsControl"  ItemsSource="{StaticResource MyData}">
      <ListView.View>
      </ListView.View>
    </ListView>
  </StackPanel>

If I un-comment line 3 (the resource definition) everything works great. However, if I comment that line out, and programmatically add the following:

public MainWindow()
{
    InitializeComponent();
    sp1.Resources.Add("MyData", new ItemsForSale());
}

I get the runtime exception A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll

I've tried adding the resource in the stackpanel's Loaded and Initialized event to no avail.

Answer 1

To sum up comments problem was caused by control that required MyData resource during initialization and threw this exception:

Cannot find resource named 'MyData'. Resource names are case sensitive

To solve the problem instead of StaticResource use DynamicResource
