有关ItemsControl Expander操作的帮助

问题描述

我正在使用Silverlight 4和VS2010.

我有一个带有ItemsControl的StackPanel.
它的ItemTemplate已绑定到其各自的DataTemplate.
它充满了几个扩展器，每个扩展器中都有大量数据.
每当我扩展其中一个扩展器时，我都希望折叠所有剩余的扩展器.

在我的项目的另一部分，我有一个类似的结构，其中扩展器是硬编码的.
为了获得相同的结果，我只需遍历StackPanel.Children集合并使用foreach桩，然后折叠所有Expander.

使用Stackpanel和ItemsControl不能做到这一点，因为ItemsControl是Stackpanel.Children上的唯一子项.

任何人都可以帮助我如何使用后面的C#代码访问每个扩展器并将其折叠起来?

Hi,

I''m using Silverlight 4 and VS 2010.

I have a StackPanel with a ItemsControl.
It''s ItemTemplate is binded to it''s respective DataTemplate.
It is filled with a few Expanders with a lot of data in each one.
Whenever I expand one of these Expanders I want to collapse all the remaining Expanders.

On another part of my project I have a similar structure where the Expanders are hard coded.
To achieve the same result I just go through the StackPanel.Children collection with a foreach cicle and collapse all the Expanders.

Using a Stackpanel and an ItemsControl I can''t do that because the Itemscontrol is the only child on the Stackpanel.Children.

Can anyone help on how do I get to each of the Expanders using c# code behind and collapse them?

<DataTemplate x:Key="AvaliacaoDataTemplate">
   <Grid>
      <toolkit:Expander x:Name="ExpanderAvaliacao" Header="{Binding}" d:LayoutOverrides="Width, Height" HeaderTemplate="{StaticResource AvaliacaoDataTemplateHeader}" Style="{StaticResource StyleExpanderBlue3}" Expanded="Expander_Expanded">
         <StackPanel>
            <!-- Lots of stuff -->
         </StackPanel>
      </toolkit:Expander>
   </Grid>
</DataTemplate>


<StackPanel x:Name="Avaliacoes">
   <ItemsControl x:Name="ItemsAvaliacao" ItemTemplate="{StaticResource AvaliacaoDataTemplate}"/>
</StackPanel>

我真的需要对此问题有所了解！
有人吗?!!
