谁帮我用ASP.NET的Gridview中镶嵌checkbox实现商品比较

Question

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
        CellPadding="4" ForeColor="#333333" GridLines="None" OnPageIndexChanging="GridView1_PageIndexChanging"
        Width="600px">
        <PagerSettings FirstPageText="首页" LastPageText="尾页" Mode="NextPreviousFirstLast"
            NextPageText="下一页" PageButtonCount="15" PreviousPageText="上一页" />
        <RowStyle BackColor="#FFFBD6" ForeColor="#333333" />
        <Columns>
        <asp:TemplateField HeaderText="选择">
        <ItemStyle HorizontalAlign="Center" />
        <ItemTemplate>
        <asp:CheckBox ID="checkbox" runat="server" />
        </ItemTemplate>
        </asp:TemplateField>
            <asp:ImageField DataImageUrlField="tupian" DataImageUrlFormatString="../shoptup/{0}"
                HeaderText="产品图片">
                <ControlStyle Height="45px" Width="60px" />
            </asp:ImageField>
            <asp:HyperLinkField DataNavigateUrlFields="shopid" DataNavigateUrlFormatString="xiangxi.aspx?id={0}"
                DataTextField="xinghao" HeaderText="型号" />
            <asp:BoundField DataField="pinpai" HeaderText="品牌" />
            <asp:BoundField DataField="pinming" HeaderText="品名" />

        </Columns>
        <FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
        <PagerStyle BackColor="#FFCC66" ForeColor="Black" HorizontalAlign="Center" />
        <SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" ForeColor="Black" HorizontalAlign="Center"
            VerticalAlign="Middle" />
        <HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
        <AlternatingRowStyle BackColor="White" />
    </asp:GridView>
这是Gridview内镶嵌checkbox作为商品标记；当我点击下面的商品比较按钮时
<asp:ImageButton
                                ID="ImageButton4" runat="server" Height="19px" ImageUrl="~/imge/bijia.png" OnClick="ImageButton4_Click" />
实现选中商品详细参数比较；后台代码怎么做呢，请高手们写详细代码；被这事郁闷好几天了啊

Answer 1

你选中了 然后点击比较 后台直接遍历 你所选择控件 然后获取到ID 来进行比较foreach   (GridViewRow   row   in   GridView1.Rows) 
                        { 
                                CheckBox   cb   =   (CheckBox)row.FindControl( "CheckBox2 "); 
                                if   (cb.Checked==true) 
                                { 
                                } 
                        }

Answer 2

需要遍历，用 row.Cell[index] 或者 row.FindCOntrol(id） 访问大概如下，
Button1_Click
{
int num = 0;
foreach(GridViewRow row in GridView1.Rows){
CheckBox chk = row.FindControl("CheckBox1") as CheckBox;
if(chk.Checked) {
string s = row.Cells[10].Text; // 得到选中行的ID
num += int.Parse(s);
}
}
}

Answer 3

关注中，也在纠结这个功能的实现，不过用的是JSP、Struts之类~

Answer 4

最简单的方法，在前台搜集选中的checkbox的值var list = document.getElementById("gridviewid").getElementsByTagName("Input");
var values= [];
for(var i = 0;i<list.length;i++)
{
    if(list[i].checked)
       values.push(list[i].value);
}
把values转成一个字符串，保存到hidden里面，提交 。

Answer 5

Button1_Click
{
int num = 0;
foreach(GridViewRow row in GridView1.Rows){
CheckBox chk = row.FindControl("CheckBox1") as CheckBox;
if(chk.Checked) {
string s = row.Cells[10].Text; // 得到选中行的ID
num += int.Parse(s);
}
}
}
