Repeater控件使用CheckBox

一、使用客户端CheckBox

<asp:Repeater runat=server ID=repeater1 DataSourceID="SqlDataSource1">
    <ItemTemplate>
    <table width=400>
    <tr>
    <td>
        <input id="Checkbox1" name="Checkbox1" type="checkbox" value='<%#Eval("ProductID")%>' /></td>
    <td><asp:Label runat=server Text='<%#Eval("ProductName")%>' ></asp:Label></td>
    <td></td>
    </tr>
    </table>
    </ItemTemplate>
    </asp:Repeater>

    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
            SelectCommand="select top 20 * from [products]"></asp:SqlDataSource>
        <asp:Button ID="ButtonSubmit" runat="server" onclick="ButtonSubmit_Click"
            Text="提交" />

    protected void ButtonSubmit_Click(object sender, EventArgs e)
    {
        if (Request.Form["Checkbox1"] != null)
        {
            string s = Request.Form["Checkbox1"].ToString();
            Response.Write(s);
        }
    }

二、使用服务器端CheckBox

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="repeater.aspx.cs" Inherits="repeater" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>

    <form id="form1" runat="server">
    <div>
    <table width=400>
    <asp:Repeater runat=server ID=Repeater1 DataSourceID="SqlDataSource1">
    <ItemTemplate>
    <tr>
    <td>
        <asp:CheckBox ID="CheckBox2" runat="server" />
        <asp:Label ID="LabelHiddenID" runat="server" Text='<%#Eval("ProductID")%>' Visible=false></asp:Label>
        </td>
        <td><asp:Label ID="Label1" runat=server Text='<%#Eval("ProductName")%>' ></asp:Label></td>
    <td></td>
    </tr>
    </ItemTemplate>
    </asp:Repeater>
    </table>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
            SelectCommand="select top 20 * from [products]"></asp:SqlDataSource>
        <asp:Button ID="ButtonSubmit" runat="server" onclick="ButtonSubmit_Click"
            Text="提交" />
    </div>
    </form>
</body>
</html>

    protected void ButtonSubmit_Click(object sender, EventArgs e)
    {
        List<string> IDlist = new List<string>();
        foreach (RepeaterItem item in this.Repeater1.Items)
        {
            Control ctrl = item.FindControl("CheckBox2");
            Control ctrlHide = item.FindControl("LabelHiddenID");
            CheckBox ck = ctrl as CheckBox;
            Label lb = ctrlHide as Label;
            if (ck != null && lb != null)
            {
                if (ck.Checked)
                {
                    IDlist.Add(lb.Text);
                }
            }
        }

        //取出IDlist中的ID值
        string IDs = "";
        foreach (string s in IDlist)
        {
            IDs += s + " ";
        }
        Response.Write(IDs);
    }
