10-15工作总结

问题:1,无法循环绑定投票的标题和选项
解决方法: 在Repeater绑定中添加ItemDataBound事件,选项用RadioButtonList绑定,附源代码:
Default页,源页面
 <div>
            广大网友对保障房建设相关问题调查<br />
            <asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
                <ItemTemplate>
                    <table>
                        <tr>
                            <td colspan="3">
                                <b>
                                    <%# Eval("t_timu")%>
                                    <asp:Literal ID="Literal1" Text='<%# Eval("t_id")%>' runat="server"></asp:Literal>
                                  
                                </b>
                            </td>
                        </tr>
                        <tr>
                            <asp:RadioButtonList ID="RadioButtonList1" runat="server" RepeatDirection="Horizontal">
                            </asp:RadioButtonList>
                        </tr>
                    </table>
                </ItemTemplate>
            </asp:Repeater>
            <br />
            <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="提交" />&nbsp;
            <asp:Button ID="Button2" runat="server" Text="查看结果" OnClick="Button2_Click" />
        </div> 

对应的cs页:
    protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        Literal Literal1 = (Literal)e.Item.FindControl("Literal1");
        RadioButtonList RadioButtonList1 = (RadioButtonList)e.Item.FindControl("RadioButtonList1");
        RadioButtonList1.DataSource = dcw_toupiao_M.dcw_toupiao_getxuanxian(Convert.ToInt32(Literal1.Text));
        RadioButtonList1.DataTextField = "x_name";
        RadioButtonList1.DataValueField = "x_id";
        RadioButtonList1.DataBind();
    }

问题2: 无法循环获得用户的选择
解决方法: 先循环Repeater控件的Item获得RadioButtonList控件,循环检测是否为选中状态,,如果是则拼接到一个字符串中,
 再把题目的编号获得拼接起来,循环添加,附源代码:

Default的cs页:
    protected void Button1_Click(object sender, EventArgs e)
    {
        string zifu = "";
        string Pid = "";
        int tiaoshu = 5;
        foreach (RepeaterItem iemt in Repeater1.Items)
        {
            RadioButtonList rbtn = iemt.FindControl("RadioButtonList1") as RadioButtonList;
            try
            {
                if (rbtn.SelectedItem.Selected)
                {
                    zifu += rbtn.SelectedItem.Value + ",";
                }
                Literal Literal1 = (Literal)iemt.FindControl("Literal1"); //e.Item.FindControl("");
                if (Literal1.Text != "")
                {
                    Pid += Literal1.Text + ",";
                }
            }
            catch (Exception ex)
            {
            }
        }
        string[] xid = null;
        xid = zifu.TrimEnd(',').Split(',');
        string[] pid = null;
        pid = Pid.TrimEnd(',').Split(',');
        if (dcw_toupiao_M.dcw_toupiao_Insert(xid, pid, tiaoshu))
        {
            this.ClientScript.RegisterClientScriptBlock(typeof(string), "ok", "<script>alert('投票成功!谢谢参与')</script>");
        }
        else
        {
            this.ClientScript.RegisterClientScriptBlock(typeof(string), "ok", "<script>alert('请完成选择')</script>");
        }
    }

DAL页:
 public static bool dcw_toupiao_Insert(string[] xid, string[] pid, int tiaoshu)
        {
            bool flag = false;
            for (int i = 0; i < pid.Length; i++)
            {
                SqlParameter[] prm = new SqlParameter[2];
                prm[0] = new SqlParameter("@xid", Int32.Parse(xid[i]));
                prm[1] = new SqlParameter("@pid", Int32.Parse(pid[i]));
                if (dcw_toupiao_M.dcw_toupiao_gettcount(Convert.ToInt32(xid[i]), Convert.ToInt32(pid[i])))
                {
                    flag = _dc_toupiao_DB.SqlHelper.ExeucteNonQuery("sm_dcw_toupiao_Insert", CommandType.StoredProcedure, prm) > 0;
                }
            }

            return flag;
        }

所掌握的技巧:
JavaScript跳转:
this.ClientScript.RegisterClientScriptBlock(typeof(string), "ok", "<script>alert('投票成功!谢谢参与')</script>");
两种获得控件的方法:
Literal Literal1 = (Literal)e.Item.FindControl("Literal1");
Literal Literal1 = e.Item.FindControl("Literal1") as Literal;
