页面传值问题（进就有分）

Question

问题描述：页面上有一个gridview和一个按钮，我在gridview加了一列checkbox,现在想实现点击按钮，将gridview里checkbox选中行的ID传给另一个页面 protected void Button_Print_Click(object sender, EventArgs e)
{
        sqlcon = new SqlConnection(strCon);
        SqlCommand sqlcom;
        for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
        {
            CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
            if (cbox.Checked == true)
            {
                string sqlstr = "Select id from MPSHZFORM1_Equip where id='" + GridView1.DataKeys[i].Value + "'";
               
            }
        }
}请问代码应该怎样补充一下，ID可能是一个集合，用什么容器传和接收？

Answer 1

get post都可以
或者用session cookie

Answer 2

在本页面中：Session["id"]=GridView1.DataKeys[i].Value;//将ID存入Session
在另一页面中：string id=Session["id"].ToString();//将Session中的ID取出

Answer 3

Response.Redirect（“xxxx.aspx？id=”+GridView1.DataKeys[i].Value）;

Answer 4

string str;
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
        {
            CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
            if (cbox.Checked == true)
            {
                 str &= GridView1.DataKeys[i].Value + "|" ;
            }
        }resoponse.redrict("xxx.aspx?id = str");
string[] str = Request.QueryString("id").Split('|'); 

Answer 5

resoponse.redrict("xxx.aspx?id = 你查出来的id");接收页 string id= Request.QueryString["id"]\或是Session也行

Answer 6

可以传递一个string类型的，然后遍历读取id...        string _ids= string.Empty; 
        for (int i = 0; i < GridView1.Rows.Count; i++)
        {
            CheckBox cbUser = (CheckBox)GridView1.Rows[i].FindControl("cbUser");
            if (cbUser.Checked == true)
            {
                      _ids+ = GridView1.Rows[i].Cells[1].Text + ",";
            }
        }
        _ids = _ids.TrimEnd(',');        Response.Redirect（“abc.aspx？id=”+_ids）;

Answer 7

我觉得拼接选中的值比较合理，通过 | 拼接，然后传过去后 spilt截取

Answer 8

在前台gridview中存  DatakeyNames="id列名"
后台
用 Gridview1.Datakyes[e.rowindex].values["id"].value; //取得你点击行的ID

Answer 9

做个例子：
GridViewCheckBoxForm.aspx  <script type="text/javascript" src="../JS/jquery-1.4.4.js"></script>
    <script type="text/javascript">
        var checkID = "";
        $(function() {
            $("input[type='button'][value='value']").click(function() {
                checkID = "";
                $("#Gridview1 input[type='checkbox']:checked").each(function() {
                    checkID += $(this).parent().next().html();
                    checkID += ",";
                });
                checkID = checkID.substring(0, checkID.length - 1);
                window.open("ReciveCheckBoxValueForm.aspx");
            });
        });
    </script>
<div>
    <asp:gridview ID="Gridview1" runat="server" AutoGenerateColumns="False" 
            DataKeyNames="ID" DataSourceID="SqlDataSource1">
        <Columns>
       <asp:TemplateField>
          <ItemTemplate>
              <asp:CheckBox ID="CheckBox1" runat="server" />
          </ItemTemplate>
       </asp:TemplateField>
            <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" 
                ReadOnly="True" SortExpression="ID" />
            <asp:BoundField DataField="NAME" HeaderText="NAME" SortExpression="NAME" />
        </Columns>
        </asp:gridview>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
            ConnectionString="<%$ ConnectionStrings:TestDBConnectionString %>" 
            SelectCommand="SELECT [ID], [NAME] FROM [Test]"></asp:SqlDataSource>
            <input type=button value='value' />
    </div>
ReciveCheckBoxValueForm.aspx <div>
        <input type=text />
    </div>
 <script src="../JS/jquery-1.4.4.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(function() {
            $("form#form1 div").eq(1).find("input").val(window.opener.checkID);
        });
    </script>

Answer 10

Response.Write("<script>window.open('xxx.aspx?id="+str+"','_blank','');</script>");string[] str = Request.QueryString("id").Split('|');
