可觀察的集合到Tabcontrol綁定

Question

    <TabControl HorizontalAlignment="Stretch" TabStripPlacement="Left" Margin="10,20,0,0"  Name="tabControl2" ItemsSource="{Binding NotesObs}" VerticalAlignment="Stretch" MinHeight="80">
        <TabItem Header="Contract Read and understood, proposal letter read and understood." Name="tabItem2" FontSize="14" IsEnabled="True">
            <Grid>
                <Border Name="b_desc"/>
                <TextBox HorizontalAlignment="Stretch" Margin="0"  Name="textBox5" Text="{Binding ContractText}"

                                         VerticalAlignment="Stretch" FontSize="12" TextWrapping="Wrap" 
                                         AutoWordSelection="True" VerticalScrollBarVisibility="Auto" 
                                         AcceptsReturn="True" 
                                         Width="{Binding ElementName=b_desc, Path=ActualWidth}" 
                                         Height="{Binding ElementName=b_desc, Path=ActualHeight}" 
                                         MaxWidth="{Binding ElementName=b_desc, Path=Width}" 
                                         MaxHeight="{Binding ElementName=b_desc, Path=Height}" />
            </Grid>
        </TabItem>
    </TabControl>

上面是我的Xaml，我的ObsCollection的名稱是

public ObservableCollection<NotesDisplay> NotesObs { get; set; }

我已經在NotesDisplay模型中正確聲明了ContractText列。 由於某種原因，我無法將其綁定，但這在數據網格中有效。 有人可以解釋我在XAML中做錯了什么嗎？

謝謝

編輯：我已經查看了鏈接的解決方案，但是在運行程序時出現選項卡。 他們確實在XAML中顯示

現在還可以，但是您必須在另一個TextBlock內容中刪除TextBlock。

你可以改變

<TextBlock>                            
  <TextBlock Text="{Binding ContractText}"/> 
</TextBlock>

至

<TextBlock Text="{Binding ContractText}"/> 

和

<TextBlock>                            
  This is <TextBlock Text="{Binding EMSText}"/>
</TextBlock>

類似於

<StackPanel Orientation="Horizontal">
  <TextBlock>This is</TextBlock>
  <TextBlock Text="{Binding EMSText}"/>
</StackPanel>
