【菜鸟日记一】DataList里面嵌套DataList进行数据绑定等操作

主要解决：通过超链接向链接页传递两个参数（其中一个值是页面Label的值）；

               DataList嵌套绑定；

               获取DataList当前行的值；

#页面代码

<asp:DataList ID="DataList3" runat="server" DataSourceID="SqlDataSource1" Width="1024px" Height="100%" OnItemDataBound="DataList3_ItemDataBound">
<ItemTemplate>
<table>
<tr>

#后台代码

//数据绑定

    protected void DataList3_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        Label lb = (Label)e.Item.FindControl("labid"); //找到控件Label的ID
        Label lba = (Label)e.Item.FindControl("Labcount"); //找到控件Label的ID
        DataList dl = (DataList)e.Item.FindControl("DataList1"); //找到嵌套在里面的DataListID
        revertmanage.CardID = lb.Text; 
        DataSet ds = revertmanage.FindRevertByCID(revertmanage, "tb_Revert");
        dl.DataSource = ds.Tables[0]; 
        dl.DataBind();
        DataSet das = revertmanage.GetReCount(revertmanage, "tb_Revert");
        lba.Text = das.Tables[0].Rows[0][0].ToString();        
    }

 

//这个主要是掌握根据DataList当前行绑定的值进行数据库查询的方法
    protected void lbtzd_Click(object sender, EventArgs e)
    {
            LinkButton lbt=sender as LinkButton;
            string cid = Convert.ToString(lbt.CommandArgument);
            if (Session["Pop_Name"] == "Adminger" || Session["Pop_Name"] == "Admin")
            {
                cardmanage.CardID = cid.ToString();
                cardmanage.TimeUp = DateTime.Now;
                cardmanage.UpdateTime(cardmanage);
                Response.Write("<script language=javascript>alert('置顶贴子成功成功！');window.location.href=window.location.href;</script>");
            }
            else

                Sessions["ID"]=null;
                Response.Redirect("Eeeor.aspx");
            }
