Answer 1

给你点提示：下面是repeater，但是方法都一样。你看看“修改”的链接就知道了。<asp:Repeater ID="rtAlbum"  runat="server">
                            <HeaderTemplate>
                            <tr class="webpageManageListTitle">
                            <td><input type="checkbox" name="allcheckbox" value="1" onclick="cball( );" /></td><td align="center"  >名称</td><td  >是否私有</td><td align="center" >创建时间</td><td  >修改</td></tr>
                            </HeaderTemplate>
                            <ItemTemplate>
                            <tr>
                             <td><input type="checkbox" name="cbAlbumId" value="<%#DataBinder.Eval(Container.DataItem,"wppaguid")%>" /></td>
                             <td align="left" ><%#DataBinder.Eval(Container.DataItem,"wppatitle")%></td>
                             <td><%#DataBinder.Eval(Container.DataItem,"wppaislock").ToString()=="True"?"锁":"不锁"%></td>
                             <td><%#DateTime.Parse(DataBinder.Eval(Container.DataItem, "wppacreatedate").ToString()).ToString("yyyy-MM-dd")%></td>
                             <td><a href="javascript:modify('<%#DataBinder.Eval(Container.DataItem,"wppaguid")%>','<%#DataBinder.Eval(Container.DataItem,"wppatitle")%>','<%#DataBinder.Eval(Container.DataItem,"wppaintro")%>','<%#DataBinder.Eval(Container.DataItem,"wppaislock")%>','<%#DataBinder.Eval(Container.DataItem,"wppapassword")%>');">修改</a></td>
                             </tr>
                            </ItemTemplate>
                </asp:Repeater>
 function modify(guid,name,des,islock,password)
        {
 
            document.getElementById("hGuid").value = guid;
            document.getElementById("textName").value = name;
            document.getElementById("textDescription").value = des;
            
            var myObj=document.getElementsByName("radioislock"); 
                for(i=0;i<myObj.length;i++){ 
                if(myObj[i].value==islock)
                     myObj[i].checked = true;
                };                 if(islock=='False')
                    document.getElementById("trpass").style.display = "none";
                else
                    document.getElementById("trpass").style.display = "";
            document.getElementsByName("radioislock").value = islock;
            document.getElementById("textpassword").value = password;
 
        }

GridView编辑时获取编辑框中的值
string quantity = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text;  protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "check")
        {
            string index= e.CommandArgument.ToString();
            GridViewRow row = GridView1.Rows[index];
            string id = row.Cells[1].Text;
        }
    }

HTML: 先创建一个gridview 然后在编辑列中添加选择列，绑定数据你就自己写吧
--------------------------------------------
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" OnSelectedIndexChanged="GridView1_SelectedIndexChanged"
            Style="position: relative" AllowPaging="True" AllowSorting="True" DataKeyNames="au_id" ForeColor="#333333" GridLines="None" OnPageIndexChanging="GridView1_PageIndexChanging" OnRowDataBound="GridView1_RowDataBound" OnSorting="GridView1_Sorting" Width="701px" OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating" OnRowCommand="GridView1_RowCommand">
            <FooterStyle BackColor="#5D7B9D" ForeColor="White" Font-Bold="True" />
            <Columns>
....
<asp:CommandField HeaderText="选择" ShowSelectButton="True" />
</Columns>
 </asp:GridView>C#：
----------------------------------------------------
//选择列事件
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {
        int id = Convert.ToInt32(GridView1.DataKeys[GridView1.SelectedIndex].Value.ToString());
        //有了主键值，写SQL语句查询数据库就行了
        string sql = "select * from table where uid = '"+ id +"'";
        SqlConnection con = new SqlConnection("server=.;uid=sa;pwd=;database=pubs");
        SqlCommand com = new SqlCommand(sql, con);
        con.Open();
        SqlDataReader dr = com.ExecuteReader();        while (dr.Read())
        {
            Text1.Text = dr["username"].ToString();
            Text2.Text = dr["..."].ToString();
            ...
        }
        dr.Close();
        con.Close();
    }
