我有一个复读机。当我点击它的任何行时我想得到 empid。？我怎样才能？我的代码是：-

<table id="table1" class="yui" cellpadding="0" cellspacing="0">
            <thead>
                <tr>
                    <th>
                        <a href='#' title="Click Header to Sort">Emp name #</a>
                    </th>
                    <th>
                        <a href='#' title="Click Header to Sort">emp sal</a>
                    </th>
                    <th>
                        <a href='#' title="Click Header to Sort">emp address</a>
                    </th>

                </tr>
            </thead>
            <tbody>
                <asp:Repeater ID="Repaddressorbbl" runat="server" OnItemCommand="Repaddressorbbl_ItemCommand">
                    <ItemTemplate>

                            </td>
                               </tr>
                    </ItemTemplate>
                </asp:Repeater>
            </tbody>
            <tfoot>
                <tr id="pagerOne1">

您必须创建手动回发。但为了使其始终有效，您的转发器应该始终绑定，即在每次回发期间。

以下代码片段可能会指导您。

using System;

namespace PostbackRef.Web
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (IsPostBack)
            {
                string arg = Request["__EVENTARGUMENT"];
                if (string.IsNullOrEmpty(arg) == false)
                {
                    if (arg.StartsWith("row"))
                    {
                        string v = arg.Substring(arg.IndexOf("#") + 1);
                        txtSelected.Text = v;
                    }
                }
            }
            //Have to bind repeater always
            Repeater1.DataBind();
        }

        protected string getPostbackReference(string Name)
        {
            return ClientScript.GetPostBackEventReference(this, "rowEvent#" + Name);
        }
    }
}

aspx 标记如下所示：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="PostbackRef.Web._Default" %>

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

        {
            font-size: 12pt;
        }
        p:hover
        {
            background-color: Gray;
            font-weight: bold;
            color: White;
        }
    </style>

    <form id="form1" runat="server">

        <asp:Repeater ID="Repeater1" runat="server" DataSourceID="ObjectDataSource1">
            <ItemTemplate>
                <p onclick="<%# getPostbackReference((string)Container.DataItem) %>">
                    <%# Container.DataItem %></p>
            </ItemTemplate>
        </asp:Repeater>
        <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetNames"
            TypeName="PostbackRef.Web.MyDs"></asp:ObjectDataSource>
        <asp:HiddenField ID="hfValue" runat="server" />
    </div>
    <div>
        Clicked : 
        <asp:TextBox ID="txtSelected" runat="server"></asp:TextBox>
    </div>
    </form>
</body>
</html>

我使用了一个 ObjectDataSource，它返回一个名称字符串数组，但数据源的选择完全由您决定。在这里我只是为了例如缘故而使用。

请注意，我在 Page_Load 上调用 Repeater1.Databind()，无论是否回发。可能有更好的方法来做到这一点。但大部分代码都在这里

YOu have to create manual postback. But for this to work always, your repeater should bind always, i.e. during each postback.

The following code snippets may guide you.

using System;

namespace PostbackRef.Web
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (IsPostBack)
            {
                string arg = Request["__EVENTARGUMENT"];
                if (string.IsNullOrEmpty(arg) == false)
                {
                    if (arg.StartsWith("row"))
                    {
                        string v = arg.Substring(arg.IndexOf("#") + 1);
                        txtSelected.Text = v;
                    }
                }
            }
            //Have to bind repeater always
            Repeater1.DataBind();
        }

        protected string getPostbackReference(string Name)
        {
            return ClientScript.GetPostBackEventReference(this, "rowEvent#" + Name);
        }
    }
}

The aspx markup looks like this:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="PostbackRef.Web._Default" %>

<!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></title>
    <style type="text/css">
        p
        {
            font-size: 12pt;
        }
        p:hover
        {
            background-color: Gray;
            font-weight: bold;
            color: White;
        }
    </style>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:Repeater ID="Repeater1" runat="server" DataSourceID="ObjectDataSource1">
            <ItemTemplate>
                <p onclick="<%# getPostbackReference((string)Container.DataItem) %>">
                    <%# Container.DataItem %></p>
            </ItemTemplate>
        </asp:Repeater>
        <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetNames"
            TypeName="PostbackRef.Web.MyDs"></asp:ObjectDataSource>
        <asp:HiddenField ID="hfValue" runat="server" />
    </div>
    <div>
        Clicked : 
        <asp:TextBox ID="txtSelected" runat="server"></asp:TextBox>
    </div>
    </form>
</body>
</html>

I've used an ObjectDataSource which returns a string array of names, but the choice of datasource is entirely yours. Here I've used just for e.g. sake.

Note that I am calling Repeater1.Databind() on Page_Load irrespective of postback or not. There are probably better ways to do this. But most of the code came exactly here

这里是带有复选框控件的示例。与按钮或任何点击事件使用的方式相同。使其成为 empid 的隐藏项。

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)

{
CheckBox box = sender as CheckBox;

RepeaterItem item = box.NamingContainer as RepeaterItem;
HiddenField hf = item.FindControl("HiddenField1") as HiddenField;string id = hf.Value;

}



<ItemTemplate>

<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="True" OnCheckedChanged="CheckBox1_CheckedChanged" />

<asp:HiddenField ID="HiddenField1" Value='<%# Eval("id") %>' runat="server" />

</ItemTemplate>

Here the sample with checkbox control. Same way you gonna use with button or any click events. Make it one hidden for empid.

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)

{
CheckBox box = sender as CheckBox;

RepeaterItem item = box.NamingContainer as RepeaterItem;
HiddenField hf = item.FindControl("HiddenField1") as HiddenField;string id = hf.Value;

}



<ItemTemplate>

<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="True" OnCheckedChanged="CheckBox1_CheckedChanged" />

<asp:HiddenField ID="HiddenField1" Value='<%# Eval("id") %>' runat="server" />

</ItemTemplate>

快速写一下

<asp:Repeater ID="Repaddressorbbl" runat="server" OnItemCommand="Repaddressorbbl_ItemCommand">
                    <ItemTemplate>
                        <tr id="gh" style="cursor: pointer" onclick="Select('<%# Eval("EmployeeID")%>');">
                            <td style="text-align: center;">
                                <%#Eval("empname")%>
                            </td>
                            <td style="text-align: center;">
                                <%# Eval("empsal")%>
                            </td>
                            <td style="text-align: center;">
                                <%# Eval("empadd")%>
                            </td>
                               </tr>
                    </ItemTemplate>
                </asp:Repeater>

试试这个

a quick write -up

<asp:Repeater ID="Repaddressorbbl" runat="server" OnItemCommand="Repaddressorbbl_ItemCommand">
                    <ItemTemplate>
                        <tr id="gh" style="cursor: pointer" onclick="Select('<%# Eval("EmployeeID")%>');">
                            <td style="text-align: center;">
                                <%#Eval("empname")%>
                            </td>
                            <td style="text-align: center;">
                                <%# Eval("empsal")%>
                            </td>

                            </td>
                               </tr>
