Question

如何从数据表中设置数据网格控件值？

我使用此来源

    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);
        }
    }

但是它收到了错误消息并且程序停止了，

类型的第一次机会异常   ＆＃39; System.Windows.Markup.XamlParseException＆＃39;发生在   PresentationFramework.dll

其他信息：无法创建＆＃39; Window1＆＃39;定义于   assembly＆＃39; ReadSky，Version = 1.0.0.0，Culture = neutral，   公钥=空＆＃39 ;.一个人的目标抛出了例外   调用。标记文件错误＆＃39; Window1.xaml＆＃39;第1行第9位。

 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>

你可以试试这个：

 <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;

dattable作为wpf中datagrid的itemssource
