asp.net gridview-使用updatepanel跨每行多行分布绑定数据
我在gridview中有一个面板，需要按行的宽度“展开”： 不管面板上有什么。我在这里展示的只是演示我的需要…我的HTML：asp.net gridview-使用updatepanel跨每行多行分布绑定数据,asp.net,gridview,updatepanel,panel,multiline,Asp.net,Gridview,Updatepanel,Panel,Multiline,我在gridview中有一个面板，需要按行的宽度“展开”： 不管面板上有什么。我在这里展示的只是演示我的需要…我的HTML： <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" CssClass="myGrid" DataKeyNames="Role_Name"> <AlternatingRowStyle Back

（不管面板上有什么。我在这里展示的只是演示我的需求…在网格视图中正确地完成这项工作很难，而不会变得笨拙
您最好使用列表视图
并使用其中的功能
<asp:ListView ID="ListView1" runat="server"
DataKeyNames="Role_Name"
OnItemCommand="ListView1_ItemCommand">
<LayoutTemplate>
<table class="myGrid">
<thead>
<tr>
<th></th>
<th>Name</th>
<th>Description</th>
</tr>
</theah>
<tbody>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />
</tbody>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr>
<td>
<asp:ImageButton ID="imgShow" runat="server" BorderStyle="None" BackColor="Transparent" ImageUrl="~/Content/Images/Arrow_Down.png" CommandName="Toggle" />
</td>
<td><%# Eval("Role_Name") %></td>
<td><%# Eval("Role_Description") %></td>
</tr>
<tr>
<td colspan="3">
<asp:Panel ID="pnlRole" runat="server" Style="position: relative;" Visible="false">
<asp:Label ID="lblAAA" runat="server" Text="aaa" /><br />
<asp:Label ID="lblBBB" runat="server" Text="bbb" /><br />
<asp:Label ID="lblCCC" runat="server" Text="ccc" /><br />
<asp:Label ID="lblDDD" runat="server" Text="ddd" /><br />
</asp:Panel>
</td>
</tr>
</ItemTemplate>
<EmptyDataTemplate>
<p>No data found.</p>
</EmptyDataTemplate>
</asp:ListView>
现在在后面的代码中，您可以引用
protected void ListView1_ItemCommand(object sender, ListViewCommandEventArgs e)
{
if (e.CommandName == "Toggle")
{
HtmlTableRow pnlRole = e.Item.FindControl("pnlRole") as HtmlTableRow;
pnlRole.Visible = !pnlRole.Visible;
ImageButton imgShow = e.Item.FindControl("imgShow") as ImageButton;
if (pnlRole.Visible == true)
imgShow.ImageUrl="~/Content/Images/Arrow_Down.png";
else
imgShow.ImageUrl="~/Content/Images/Arrow_Up.png";
}
}
以下是我的想法-
左侧是“关闭”所有行时的GridView。右侧，在“打开”两行之后：
标记：
<form id="form1" runat="server" style="">
<asp:ScriptManager runat="server"></asp:ScriptManager>
<table runat="server" style="font-weight: bold; margin: 0 auto; font-family: Arial;">

<td style="text-align: center; width: 500px; overflow: hidden">
<asp:GridView ID="grv_Four_Rows" runat="server"
AutoGenerateColumns="False" BackColor="black" GridLines="None"
CellPadding="3" CssClass="myGrid" DataKeyNames="Test1_First_Name">
<HeaderStyle CssClass="myGridHeader" />
<RowStyle BackColor="#b5c7de" />
<AlternatingRowStyle BackColor="#d1e0e0" />
<Columns>
<asp:TemplateField>
<ItemStyle HorizontalAlign="Left" />
<HeaderTemplate>

<td style="width: 150px;">First</td>
<td style="width: 150px;">Last</td>

表格：
我仍然有很多格式和外观问题，但对于这些问题，我将打开一篇新帖子。
希望它对其他人有所帮助。请看一下谢谢，但是面板中的数据不是行数据的一部分（来自数据库中的表）。无论我如何格式化和填充面板以及我在其中放置了什么，我只需要它像gridview中的新行一样。（我希望我现在解释得更好）然后考虑做同一个科尔斯潘，但最后一分钟，我会检查它，然后让你知道它是如何出来的。谢谢。我发现找不到类型或命名空间名称“HtmlTableRow”
。调查。尝试包括System.Web.UI.WebControls
。请参阅ahhh:usingsystem.Web.UI.HtmlControls所需的它编译但运行它时只显示页眉。ListView根本不显示。明天将继续。现在谢谢你！！！
