如何从aspx.cs文件中复制.aspx ListView(包括它的LayoutTemplate和ItemTemplate)? .aspx.cs使用DataBind()在页面上显示值。
基本上我想转此:
<asp:ListView ID="EvalAnswerList" OnItemDataBound="EvalAnswerList_ItemDataBound" runat="server">
<LayoutTemplate>
<table cellpadding="2" width="640px" border="1" runat="server" class="altRows" id="tblProducts">
<tr id="Tr1" runat="server">
<th id="Th1" runat="server">Question
</th>
</tr>
<tr runat="server" id="itemPlaceholder" />
</table>
</LayoutTemplate>
<ItemTemplate>
<tr id="Tr2" runat="server">
<td>
<asp:Label ID="QuestionTextLabel" Font-Bold="true" runat="server" />
</td>
</tr>
</ItemTemplate>
</asp:ListView>
进入这个:
<asp:ListView ID="EvalAnswerList" OnItemDataBound="EvalAnswerList_ItemDataBound" runat="server">
<LayoutTemplate>
<table cellpadding="2" width="640px" border="1" runat="server" class="altRows" id="tblProducts">
<tr id="Tr1" runat="server">
<th id="Th1" runat="server">Question
</th>
</tr>
<tr runat="server" id="itemPlaceholder" />
</table>
</LayoutTemplate>
<ItemTemplate>
<tr id="Tr2" runat="server">
<td>
<asp:Label ID="QuestionTextLabel" Font-Bold="true" runat="server" />
</td>
</tr>
</ItemTemplate>
</asp:ListView>
<asp:ListView ID="EvalAnswerList" OnItemDataBound="EvalAnswerList_ItemDataBound" runat="server">
<LayoutTemplate>
<table cellpadding="2" width="640px" border="1" runat="server" class="altRows" id="tblProducts">
<tr id="Tr1" runat="server">
<th id="Th1" runat="server">Question
</th>
</tr>
<tr runat="server" id="itemPlaceholder" />
</table>
</LayoutTemplate>
<ItemTemplate>
<tr id="Tr2" runat="server">
<td>
<asp:Label ID="QuestionTextLabel" Font-Bold="true" runat="server" />
</td>
</tr>
</ItemTemplate>
</asp:ListView>
此复制必须在aspx.cs文件中完成。显然它不会完全是这样,但我想让你知道我想要做什么。 我试过说:
ListView test = new ListView();
PlaceHolder.Controls.Add(test);
test = EvalAnswerList;
然后尝试在test.DataBind()中使用它,但它不起作用。

您可以使用webusercontrol,请尝试以下步骤
步骤1:创建用户控件并将列表视图放在
中<%@ Control Language="C#" AutoEventWireup="true" CodeFile="CustomListView.ascx.cs"
Inherits="CustomListView" %>
<asp:ListView ID="EvalAnswerList" OnItemDataBound="EvalAnswerList_ItemDataBound"
runat="server">
<layouttemplate>
<table cellpadding="2" width="640px" border="1" runat="server" class="altRows" id="tblProducts">
<tr id="Tr1" runat="server">
<th id="Th1" runat="server">Question
</th>
</tr>
<tr runat="server" id="itemPlaceholder" />
</table>
</layouttemplate>
<itemtemplate>
<tr id="Tr2" runat="server">
<td>
<asp:Label ID="QuestionTextLabel" Font-Bold="true" runat="server" />
</td>
</tr>
</itemtemplate>
</asp:ListView>
enter code here
Setp 2:创建一个公共DataSet / DataTable以在页面加载中绑定listview
public DataSet dsSource = new DataSet();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
EvalAnswerList.DataSource = dsSource;
EvalAnswerList.DataBind();
}
}
enter code here
步骤3:现在在aspx页面中添加对usercontrol的引用
<%@ Reference Control="CustomListView.ascx" %>
enter code here
步骤4:最后,现在您可以在aspx中多次使用该列表视图。拿一个面板或div,然后将usercontrol添加到你想要的位置。
CustomListView clv = new CustomListView();
clv.dsSource = ds;//dataset/datatable to bind listview
div.Controls.Add(clv);
gud luck!
