嵌套gridview C＃

Question

我在我的页面中嵌套gridview。第一个像头一样使用，所以这将显示段名称。第二个用于显示段细节。一切都很好，除了我在设计第一个网格时遇到问题。我想在此页面显示数据的方式是 段（换行符） 详细信息

但它在一行中显示为段详细信息。我将如何使网格出现在占用页面整个宽度的两行中。这是目前如何设置的。

<asp:GridView ID="gvSegments" runat="server" AutoGenerateColumns="false" GridLines="None" Width="900px" OnRowDataBound="gvSegments_RowDataBound">

一种方式做到这一点操作（虽然也许不是你要找的）是把两个嵌套的GridView在同一ItemTemplate中为你的另一首列具有突破和/或水平线或类似的东西那。它可能看起来像：

<asp:GridView ID="gvSegments" runat="server"> 
<Columns> 
    <asp:TemplateField> 
     <ItemTemplate> 
      <asp:HiddenField /> 
      <asp:Label /> 

      <br /> 
      <hr /> 

      <asp:GridView /> 
     </ItemTemplate> 
    </asp:TemplateField> 
</Columns> 
</asp:GridView> 

然后使该行跨越你可以添加和ItemStyle到您的模板列

<asp:TemplateField ItemStyle-Width="100%">
