屬性名稱不適用於我的datagrid列綁定

Question

剛開始學習WPF XAML中的DataGrid。這是代碼：

型號

Public Class Idea 
    Public Property IdeaID() As Integer 
    Public Property Name() As String 
End Class 

視圖模型

Public Class IdeaViewModel 
    Implements INotifyPropertyChanged 

    Public Shared Property allIdeas() As New ObservableCollection(Of Idea) 

    Public Sub New() 
    For index = 1 To 10 
     Dim anitem As New Idea 
     anitem.Name = "Value " & index 
     allIdeas.Add(anitem) 
    Next 
    End Sub 

    Public ReadOnly Property AddAnItemToList() As ICommand 
    Get 
     Return New RelayCommand(AddressOf InsertAnItem) 
    End Get 
    End Property 

    Public Sub InsertAnItem() 
    Dim anItem As New Idea 
    anItem.Name = "Item " & allIdeas.Count() 
    allIdeas.Add(anItem) 
    End Sub 

    Public ReadOnly Property ClearTheList() As ICommand 
    Get 
     Return New RelayCommand(AddressOf ClearStoredList) 
    End Get 
    End Property 

    Public Sub ClearStoredList() 
    allIdeas.Clear() 
    End Sub 


    Public Event PropertyChanged As PropertyChangedEventHandler _ 
     Implements INotifyPropertyChanged.PropertyChanged 
End Class 

視圖（XAML只，沒有後面的代碼）

<Window x:Class="IdeaView" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     xmlns:sys="clr-namespace:System;assembly=mscorlib"   
     xmlns:local="clr-namespace:MVVM7" 
     Title="IdeaView" Height="500" Width="200" WindowStartupLocation="CenterScreen"> 
    <Window.DataContext> 
    <local:IdeaViewModel/> 
    </Window.DataContext> 

    <StackPanel> 
     <Button Margin="25" Height="50" Content="Insert an item" Command="{Binding AddAnItemToList}"/> 
     <Button Margin="25" Height="50" Content="Clear stored list" Command="{Binding ClearTheList}"/> 

    <DataGrid Height="100" 
       ItemsSource="{Binding allIdeas}" 
       AutoGenerateColumns="True" 
       > 
    </DataGrid> 

    <DataGrid Height="100" 
       AutoGenerateColumns="False" 
       > 
     <DataGridTextColumn Binding="{Binding allIdeas}"/> 
     <DataGridTextColumn Binding="{Binding allIdeas}"/> 
    </DataGrid> 

    </StackPanel> 
</Window> 

的第一個DataGrid上來的罰款。第二個DataGrid當然不是因爲您無法將列綁定到整個allIdeas對象。我只是將代碼留在指出我知道我想要的東西像"{Binding Name}"，但我綁定DataGrid的方式不正確&我一直無法找到一個帖子，解決這個問題在這樣一個基本水平。

我想在DataGrid中以雙向綁定的方式工作，但我想確保我理解數據如何首先連接。這就是爲什麼我試圖手動將ViewModel的ObservableCollection的屬性綁定到DataGrid中的列。

Answer 1

我修改AQuirky的回答，但他似乎在此刻已經漸行漸遠。他的答案在其中有一個錯誤。

<DataGrid Height="100" 
      ItemsSource="{Binding allIdeas}" 
      AutoGenerateColumns="False" 
      > 
    <DataGrid.Columns> 
     <DataGridTextColumn Binding="{Binding IdeaID}"/> 
     <DataGridTextColumn Binding="{Binding Name}"/> 
    </DataGrid.Columns> 
</DataGrid> 

Answer 2

嘗試......

<DataGrid Height="100" 
      ItemsSource="{Binding allIdeas}" 
      AutoGenerateColumns="False" 
      > 
    <DataGridTextColumn Binding="{Binding IdeaID}"/> 
    <DataGridTextColumn Binding="{Binding Name}"/> 
</DataGrid>
