前臺代碼



 <asp:TemplateField HeaderText="Check">

                        <ItemTemplate>

                            <asp:CheckBox ID="CheckBox1" runat="server" />

                        </ItemTemplate>

                        <HeaderStyle Width="1%" Wrap="false" />

                        <ItemStyle HorizontalAlign="Center" />

                    </asp:TemplateField>

后臺代碼



 protected void BtnResend_Click(object sender, EventArgs e)

    {

        string YourID = "";

        for (int i = 0; i < GridView1.Rows.Count; i++)

        {

            CheckBox CheckBox1 = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("CheckBox1");

            if (CheckBox1.Checked)

                YourID += GridView1.Rows[i].Cells[1].Text.Trim();

                YourID += ",";

            }

        }

        string YourIDString = YourID.TrimEnd(',');

        Response.Redirect("YourPageB.aspx?YourID =" + YourID);

        //也可以用session傳值

1.模板列添加chackbox
2.遍歷Gridview，如果選中，記錄下keyID，組合成一個數組或字符串到另一個頁面。

HTML code
<asp:TemplateField HeaderText="Check">
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" />
</ItemTemplate>
<HeaderStyle Width="1%" Wrap="false" />
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>

不行，插入为空

接收为b.php

<?
$title=$_post['title']
?>

怎么实现，用GridView的模板列：
<asp:TemplateField>
<ItemStyle HorizontalAlign="Center" Width="4%" />
<ItemTemplate>
<asp:CheckBox ID="cb" runat="server" onclick="a(this);" />
</ItemTemplate>
</asp:TemplateField>
方法就如一楼说的，循环去取
