Question

我正在使用Visual Studio 2010中的C＃上的wpf。通过sqlserver创建DataGrid并想设置Header的大小我的c＃代码是

private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            SqlConnection con = new SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename=D:\\FUDA\\fuda.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True");
            SqlDataAdapter da = new SqlDataAdapter();
            con.Open();
            DataTable dt = new DataTable();
            da.SelectCommand = new SqlCommand("select * from user_ctrl",con);
            da.Fill(dt);
            dataGrid1.ItemsSource = dt.DefaultView;
        }

Xaml Code是

<TabControl Height="311" HorizontalAlignment="Left" Name="tabControl1" VerticalAlignment="Top" Width="503">
            <TabItem Header="tabItem1" Name="tabItem1">
                <Grid>
                    <DataGrid Height="278" HorizontalAlignment="Left" Margin="1,1,0,0" Name="dataGrid1" VerticalAlignment="Top" Width="492" />
                </Grid>
            </TabItem>
        </TabControl>

上面的代码工作正常，但每当我尝试添加xaml自定义大小到Header时，给我错误“在'DataGrid'类型中找不到可附加属性'列'” 注意：我已禁用“自动生成列”

为什么＆amp;如何解决这个问题
默认情况下也要按字母顺序排列属性窗口（如果设置存在），Where＆amp;怎么样？

当我将它放在xaml中时，它对我有用：

    <TabControl Height="311" HorizontalAlignment="Left" Name="tabControl1" VerticalAlignment="Top" Width="503">
        <TabItem Header="tabItem1" Name="tabItem1">
            <Grid>
                <DataGrid Height="278" HorizontalAlignment="Left" Margin="1,1,0,0" Name="dataGrid1" VerticalAlignment="Top" Width="492">
                    <DataGrid.Columns>
                        <DataGridTextColumn Width="100" Header="Column 1" Binding="{Binding}" />
                        <DataGridTextColumn Width="100" Header="Column 2" Binding="{Binding}" />
                        <DataGridTextColumn Width="100" Header="Column 3" Binding="{Binding}" />
                    </DataGrid.Columns>
                </DataGrid>
            </Grid>
        </TabItem>
    </TabControl>

没有错误被我抛出......我希望这对你有所帮助：）
