我想点击btndelete,每个复选框,其中chechek在repeater1中获取列(titr)的值在同一行,但我没有找到选中的复选框,并且不能访问列的值(titr)
<asp:Repeater ID="Repeater1" runat="server">
<HeaderTemplate>
<table>
<tr>
<td> </td>
<td>subject</td>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<asp:CheckBox ID="CheckBox1" runat="server" />
</td>
<td id="checkvalue" >
<%# Eval("titr") %>
</td>
</tr>
</ItemTemplate>
<FooterTemplate></table></FooterTemplate>
</asp:Repeater>
<asp:Button ID="btndelete" runat="server" Text="delete" OnClick="btndelete_Click" />
.cs代码是:
protected void btndelete_Click(object sender, EventArgs e)
{
}

您可以使用linq获取每个选中复选框的repeaterItem列表,以便:
List<RepeaterItem> selectedItems = Repeater1.Items.Cast<RepeaterItem>().Where(x => ((CheckBox)x.FindControl("CheckBox1"))
.Checked).ToList();
然后,您可以遍历列表并获取每个选定行的titr值,但您必须将某个服务器控件设置为等于&#34; titr&#34;绑定控件时,如:
<asp:literal id="literal1" runat="server"><%# Eval("titr") %></asp:literal>
这样你可以在迭代列表后找到这个值,如下所示:
List<string> titrValues = selectedItems.Select(t => ((Literal)t.FindControl("literal1).Text));
您可能需要进行一些调整,但这应该为您获得具有选定值的每行的titr值。

Aspx代码:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:Repeater ID="Repeater1" runat="server" >
<ItemTemplate>
<div>
<asp:CheckBox ID="CategoryID" runat="server" Text='<%# Eval("val") %>' />
</div>
</ItemTemplate>
</asp:Repeater>
<asp:Button Text="Click" OnClick="Button2_Click" runat="server" />
</form>
</body>
</html>
CS代码:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataTable dt = new DataTable();
dt.Columns.Add("val", typeof(string));
for (int i = 0; i < 10; i++)
dt.Rows.Add("testing" + i.ToString());
Repeater1.DataSource = dt;
Repeater1.DataBind();
}
}
protected void Button2_Click(object sender, EventArgs e)
{
string Rpt = "Repeater Items Checked:<br />";
for (int i = 0; i < Repeater1.Items.Count; i++)
{
CheckBox chk = (CheckBox)Repeater1.Items[i].FindControl("CategoryID");
if (chk.Checked)
{
Rpt += (chk.Text + "<br />");
}
}
Response.Write(Rpt);
}
您还可以使用断点来检查获取值....
