Question

昨天我安装了C＃3.5，今天在阅读“使用Google Data API使用C＃访问Google Spreadsheets”这一主题时，我决定尝试一下。

所以我决定写一个例子，那个： 1）获取第一个电子表格的第一个工作表的数据馈送，该名称包含用户插入的字符串段 2）用数据填充网格

我得分开，用电子表格值数据填充二维数组或列表列表。我坚持找到一个控件来放入数据并动态生成它，因为我事先不知道工作表的行或列。

我的直觉说，我可以改变List＆gt;使用数据集，并开始尝试不同的控件，IntelliSense抛出我。我知道我应该先读一本书，但我不耐烦而不先试试。

的Xaml

<DockPanel Background="LightSteelBlue">

    <!-- Standard input -->
    <DockPanel DockPanel.Dock="Top" Margin="5">
        <TextBlock Margin="10,0,5,0" VerticalAlignment="Center">Username:</TextBlock>
        <TextBox x:Name="username" Width="120" Padding="5,0,5,0" Text="username@gmail.com" />
        <TextBlock Margin="10,0,5,0" VerticalAlignment="Center">Password:</TextBlock>
        <TextBox x:Name="password" Width="120" Padding="5,0,5,0" Text="password" />
        <TextBlock Margin="10,0,5,0" VerticalAlignment="Center">Workbook:</TextBlock>
        <TextBox x:Name="workbookname" Width="120" Padding="5,0,5,0" Text="name" />
        <Button x:Name="getData" Margin="5,0,0,0" Padding="5,0,5,0" Content="Get _Data" Click="getData_Click" />
    </DockPanel>

    <!-- Grid display -->
    <ListBox Name="lb2"/>

</DockPanel>

Answer 1

我在WPFToolkit中使用了这个：

<my:DataGrid Margin="0,29,0,0" Name="dataGridView" xmlns:my="http://schemas.microsoft.com/wpf/2008/toolkit" AlternatingRowBackground="AliceBlue" ItemsSource="{Binding Path=.}" CanUserResizeRows="False" ClipboardCopyMode="IncludeHeader" IsReadOnly="True" IsTabStop="True" AutoGeneratedColumns="dataGridView_AutoGeneratedColumns" />

用一些代码填充它：

private DataTable dataTable;

public Constructor()
{
    ....
    this.dataTable = new DataTable();

    dataGridView.DataContext = dataTable;
    ....
}

在C＃3.5中填充网格
