关于GridView多行选择

[erytbc]

<asp:GridView ID="GridView1"  runat="server" AutoGenerateColumns="False"  Width="95%" >
                <Columns>
                    <asp:TemplateField>
                        <ItemTemplate>
                             <asp:CheckBox ID="chkExport" runat="server" />
                                <asp:TextBox ID="num" runat="server" Width="25px" Text="0"></asp:TextBox>
                           
                        </ItemTemplate> 
                        
                    </asp:TemplateField>
                    <asp:TemplateField>
                    <ItemTemplate><input id="name" type="hidden" runat="server" value='<%# bind("Freight_Info_id") %>'/>
                            <input id="id" type="hidden" runat="server" value='<%# bind("Freight_Info_Name") %>' />
                             </ItemTemplate> 
                             </asp:TemplateField>
                    <asp:BoundField DataField="Freight_Info_Name" HeaderText="全称" />
                    <asp:BoundField DataField="Freight_Info_ShortName" HeaderText="简称" />
                    <asp:BoundField DataField="Freight_Factory_Name" HeaderText="供应厂家" />
                    <asp:BoundField DataField="Freight_Info_Model" HeaderText="型号" />
                    <asp:BoundField DataField="Freight_Info_Pressure" HeaderText="压力" />
                    <asp:BoundField DataField="Freight_Info_Material" HeaderText="材质" />
                </Columns>
            </asp:GridView>

后台：

foreach (GridViewRow g in GridView1.Rows)
        {
            CheckBox ChkTmp;
            ChkTmp = (CheckBox)g.FindControl("chkExport");
            Response.Write("<script>alert('" + ChkTmp.Checked + "')</script>");
        }

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

            CheckBox ChkTmp = (CheckBox)GridView1.Rows[i].FindControl("chkExport");

            Response.Write("<script>alert('" + ChkTmp.Checked + "')</script>");
}

为什弹出来的 都是False？ 怎么办？

后台数据绑定代码怎么写的？

       Dt = user.Search_Freight_Info(ff, Freight_Info_DatetimeA, Freight_Info_DatetimeA, SearchFlagTmp, currpage, this.PhInfoPager.Per, this.PhInfoPager.PreviousRecords, 1);
        this.PhInfoPager.Total = Dt.Rows.Count > 0 ? (Dt.Rows[0]["TotalItem"] != null ? Convert.ToInt32(Dt.Rows[0]["TotalItem"]) : 0) : 0;
        this.PhInfoPager.Calculate();
        Dt.Clear();
        Dt = user.Search_Freight_Info(ff, Freight_Info_DatetimeA, Freight_Info_DatetimeA, SearchFlagTmp, currpage, this.PhInfoPager.Per, this.PhInfoPager.PreviousRecords, 0);
        
        GridView1.DataSource = Dt;
        GridView1.DataBind();

能取出数据的

我是问你是否将绑定的代码放到了if （!IsPostBack){ }里？
