AutoCompleteBox是邪惡的

爲什麼AutoCompleteBox恨我？我花了至少3天的時間試圖讓ACB在下拉列表中顯示數據。我所得到的是下拉列表中的類名稱。列表框完美地工作。

謝謝您的時間和努力！

繼承人的什麼它做一個圖片：

現在繼承人的XAML爲ListBox

<ListBox Height="100" HorizontalAlignment="Left" Margin="367,81,0,0" Name="ListBox1" VerticalAlignment="Top" Width="184" ItemsSource="{Binding}" > 
     <ListBox.ItemTemplate> 
      <DataTemplate> 
       <StackPanel Orientation="Horizontal"> 
        <TextBlock Text="{Binding Together}" /> 
        <TextBlock Text=" sadssa" /> 
       </StackPanel> 
      </DataTemplate> 
     </ListBox.ItemTemplate> 
    </ListBox>

下面是該AutoCompleteBox

<sdk:AutoCompleteBox x:Name="atcTextBox" ItemsSource="{Binding}" ValueMemberPath="CountryNumber" FilterMode="StartsWith" 
      IsTextCompletionEnabled="True" Height="30" MinimumPopulateDelay="0" MinimumPrefixLength="0" Margin="29,225,259,225"> 
      <sdk:AutoCompleteBox.ItemTemplate> 
       <DataTemplate> 
        <StackPanel Orientation="Horizontal"> 
         <TextBlock Text="{Binding Path=CountryName}" /> 
         <TextBlock Text="{Binding Path=Together}" /> 
        </StackPanel> 
       </DataTemplate> 
      </sdk:AutoCompleteBox.ItemTemplate> 
     </sdk:AutoCompleteBox>

和代碼Behide的XAML。

Partial Public Class pgMain 
    Inherits Page 

    Public Sub New() 
     InitializeComponent() 

     Dim a = GetCountry() 
     ListBox1.ItemsSource = a 
     atcTextBox.ItemsSource = a 
    End Sub 

    Private Function GetCountry() As List(Of Country) 
     Dim lstCountry As New List(Of Country)() 
     lstCountry.Add(New Country() With {.CountryName = "India"}) 
     lstCountry.Add(New Country() With {.CountryName = "USA"}) 
     lstCountry.Add(New Country() With {.CountryName = "Australia"}) 
     lstCountry.Add(New Country() With {.CountryName = "Germany"}) 
     lstCountry.Add(New Country() With {.CountryName = "England"}) 
     Return lstCountry 
    End Function 

End Class 

Public Class Country 
    Private m_CountryName As String 
    Public Property CountryName() As String 
     Get 
      Return m_CountryName 
     End Get 
     Set(ByVal value As String) 
      m_CountryName = value 
     End Set 
    End Property 

    Private m_CountryNumber As Integer 

    Public Property CountryNumber As Integer 
     Get 
      Return m_CountryNumber 
     End Get 
     Set(value As Integer) 
     End Set 
    End Property 

    Public ReadOnly Property Together 
     Get 
      Return m_CountryName & " " & m_CountryNumber.ToString 
     End Get 
    End Property 

    Public Sub New() 
     m_CountryNumber = Rnd(Timer) * 100 
    End Sub 
End Class

嘗試改變{綁定路徑=國家或地區名稱}和{綁定路徑=共同}到{TempateBinding國家或地區名稱}和{一起TempateBinding}。如果這沒有幫助，請恢復更改並嘗試從xaml中移除設置ItemsSource，並將atcTextBox.ItemsSource = a行替換爲atcTextBox.DataContext = a。讓我知道如果這有助於:)。 – 2012-02-22 19:00:57

那麼，TemplateBinding CountryName會給出錯誤信息，在類型'Control'中找不到CountyName。如果我刪除了XAML的ItemSource並將ItemSource = a替換爲DataContect = a，則下拉效果停止工作。沒有任何顯示）在另一個注意事項..我添加了一個轉換器到AutoCompleteBox.ItemTemplate中的文本框之一，並且轉換器從未被命中（調試） – 2012-02-22 20:13:51

評論＃2：我試過這個，它不工作或者http ：//msdn.microsoft.com/en-us/library/Dd833083（v = vs.95）.aspx – 2012-02-22 20:23:19

找到答案。

主題引發了自動完成框中的錯誤。我刪除了主題，現在「自動填充」框正在工作。

<toolkit:Theme ThemeUri="/System.Windows.Controls.Theming.BureauBlue;component/Theme.xaml"> 
    </toolkit:Theme>

我們看看是否有針對修復..
