datatable作爲wpf中datagrid的項目源

Question

如何從數據表中設置datagrid控件值？

我用這個源

public static readonly DependencyProperty ObjDataTableDefaultViewProperty = DependencyProperty.Register("ObjDataTableDefaultView", typeof(System.Data.DataView), typeof(Window1), new FrameworkPropertyMetadata()); 

    public System.Data.DataView ObjDataTableDefaultView 
    { 
     get { return (System.Data.DataView)GetValue(ObjDataTableDefaultViewProperty); } 
     set { SetValue(ObjDataTableDefaultViewProperty, value); } 
    } 
    private void CreateObjDataTable() 
    { 
     try 
     { 
      ObjDataTableDefaultView = table.DefaultView; 
     } 
     catch (Exception ex) 
     { 
      MessageBox.Show(ex.Message); 
     } 
    } 

但它已經得到了一個錯誤信息，然後程序停止，

發生的類型 「System.Windows.Markup.XamlParseException」第一次機會異常in PresentationFramework.dll

附加信息：無法創建在 程序集中定義的'Window1'實例'ReadSky，Version = 1.0.0.0，Culture = neutral， PublicKeyToken = null'。 調用的目標已拋出異常。錯誤標記文件「Window1.xaml」 1個線9號位置

My XAML 

<Window x:Class="ReadSky.Window1" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Title="Window1" Height="296" Width="738" xmlns:my="http://schemas.microsoft.com/wpf/2008/toolkit"> 
    <Grid> 
     <my:DataGrid AutoGenerateColumns="False" Margin="36,30,39,90" Name="gridCtrl" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" IsReadOnly="True" RowBackground="Gray" AlternatingRowBackground="White" ItemsSource="{Binding ObjDataTableDefaultView, ElementName=uc, Mode=OneWay}"/> 
    </Grid> 
</Window> 

Answer 1

你可以試試這個：

<DataGrid Name="grid" AutoGenerateColumns="True" ItemsSource="{Binding}" />  

public DataTable TableData { 
     get { 
      DataTable dt = new DataTable(); 
      dt.Columns.Add("col1"); 
      dt.Columns.Add("col2"); 
      dt.Rows.Add(new string[] {"val1", "val2"}); 
      return dt; 
     } 
    } 

grid.DataContext = TableData;
